The 8th Donaldson Tournament 2026 takes place on December 5–6, 2026, at the historic Mechanics’ Institute Chess Club in downtown San Francisco, California. The two-day classical tournament features four Swiss-system rounds across three rating sections: 2000+, 1600–1999, and Under 1600.
All games use a classical G/90+30 time control. Each player receives 90 minutes for the game with a 30-second increment from move one. Furthermore, all sections are both US Chess and FIDE rated, making the tournament particularly attractive to players looking to compete for both national and international rating.
The tournament advertises a $2,600 prize fund based on 80 fully paid entries. Mechanics’ Institute also plans to broadcast the top six games online with a 15-minute delay.

Players wishing to enter the 2000+ section must have at least an 1800 US Chess Regular Supplemental or actual regular rating.
Players wishing to enter the 1600–1999 section must have at least a 1400 US Chess Regular Supplemental or actual regular rating.
Play-Up Fees
| Player | Play-Up Fee |
|---|---|
| Mechanics’ Institute Member | $15 |
| Non-Member | $20 |
Players should select the appropriate section during registration and pay the additional play-up fee when applicable.
📅 Schedule
The tournament takes place over two days, with two rounds each day.
| Date / Time | Program |
|---|---|
| Saturday, December 5 – 9:30–9:45 AM | On-site registration |
| Saturday, December 5 – 10:00 AM | Round 1 |
| Saturday, December 5 – 2:30 PM | Round 2 |
| Sunday, December 6 – 10:00 AM | Round 3 |
| Sunday, December 6 – 2:30 PM | Round 4 |
Players should arrive before 9:45 AM on Saturday, particularly if they need to complete on-site registration.
Round 3 pairings are scheduled to be prepared on Sunday morning at 9:30 AM. Consequently, players needing to withdraw or request an eligible bye should notify the Chess Club before pairings are produced.
The two-round-per-day structure leaves a substantial break between rounds and avoids the very late evening finishes common at some weekend congresses.

| Phone | +1 415-393-0110 |
Alex Robins serves as Chess Director at Mechanics’ Institute. The tournament team also includes Head of Tournaments Judit Sztaray and several experienced tournament directors.
📍 Venue
Mechanics’ Institute, 4th Floor – 57 Post Street, San Francisco, CA 94104, United States.
The tournament is held in the historic Mechanics’ Institute building in the heart of downtown San Francisco.
The Chess Club occupies the fourth floor and has a long tradition of organizing major rated tournaments, lectures, classes, casual play, and community chess events.
The building is exceptionally convenient for players using public transportation. Mechanics’ Institute states that it is located only half a block from Montgomery Street BART and Muni stations.
The official US Chess listing identifies the tournament site as handicap accessible.
Players who require a specific accessibility arrangement may nevertheless wish to contact the Chess Club before the event.
🏨 Accommodation
Mechanics’ Institute does not advertise an official tournament hotel or negotiated room block for the Donaldson Tournament.
However, several hotels are available within easy walking distance of the venue in downtown San Francisco.
| Hotel | Approx. Price / Night |
|---|---|
| The Marker Union Square San Francisco – 501 Geary Street, San Francisco, CA 94102 | Approx. $110–$150 |
| Hotel 32One – 321 Grant Avenue, San Francisco, CA 94108 | Approx. $140–$180 |
| The Westin St. Francis San Francisco on Union Square – 335 Powell Street, San Francisco, CA 94102 | Approx. $180–$230 |
The Marker Union Square San Francisco
501 Geary Street, San Francisco, CA 94102
The Marker offers a comparatively affordable full-service option in the Union Square area and remains within a manageable walk or short local ride of Mechanics’ Institute.
It can be a practical choice for players who want to stay downtown without paying the highest Financial District hotel rates.
Hotel 32One
321 Grant Avenue, San Francisco, CA 94108
Hotel 32One is particularly well located for the tournament, between the Union Square and Financial District areas.
Its Grant Avenue location puts it within easy walking distance of 57 Post Street, reducing the need for transportation on tournament mornings.
The Westin St. Francis San Francisco on Union Square
335 Powell Street, San Francisco, CA 94102
The Westin St. Francis is a larger upscale hotel directly on Union Square and provides another convenient option within walking distance of the tournament.
It may be particularly suitable for families or visitors who prefer a larger full-service hotel in central San Francisco.
Prices are approximate public rates and are not official tournament rates. Actual December 5–6 prices may differ according to room type, taxes, cancellation terms, availability, and booking date. Players should check live rates before reserving.
🚆 How to Get There
The Mechanics’ Institute is particularly easy to reach by public transportation because it sits immediately next to San Francisco’s Market Street transit corridor.
🚆 By BART
The nearest station is:
Montgomery Street BART Station – 598 Market Street, San Francisco, CA 94104
Mechanics’ Institute is approximately half a block from Montgomery Street Station.
Montgomery is served by several BART lines and provides connections throughout San Francisco and the wider Bay Area.
For many tournament participants, particularly visitors staying elsewhere in San Francisco or the East Bay, BART may be easier than driving into the downtown area.
🚋 By Muni
Montgomery Street Station also connects with San Francisco Muni services.
This gives players additional options for reaching the venue from neighborhoods throughout San Francisco.
✈️ From San Francisco International Airport
San Francisco International Airport (SFO) has a BART station inside the International Terminal.
BART connects SFO directly with downtown San Francisco, and the journey to the downtown area takes approximately 30 minutes.
Players can travel from SFO to Montgomery Street Station and then walk the short remaining distance to Mechanics’ Institute.
This makes the tournament unusually convenient for players arriving by air because a rental car is not necessary.
🚗 By Car
For navigation, use:
Mechanics’ Institute – 57 Post Street, San Francisco, CA 94104, United States.
Downtown San Francisco parking can be expensive and limited. The nearby Montgomery BART station itself does not have a parking facility.
Players who intend to drive should therefore identify a commercial downtown parking garage in advance and allow additional time for parking before Round 1.
For most visitors staying near a BART station, public transportation may be the simpler option.
ℹ️ Other Information
🌐 FIDE & US Chess Rating
All tournament games are US Chess Regular rated and FIDE rated.
Mechanics’ Institute states that modified FIDE rules apply.
This gives participants an opportunity to play four classical games that can affect both their US Chess and FIDE ratings.
⏰ Forfeit Time
The organizer publishes two different forfeit limits depending on whether advance notice has been provided.
| Situation | Forfeit Time |
|---|---|
| No prior notice | 30 minutes |
| Organizer notified in advance | 60 minutes |
A player expecting to arrive late should email or call the Chess Club as soon as possible.
When an opponent does not appear, the organizer will make every reasonable effort to find the waiting player an extra game.
♟️ Chess Equipment
Mechanics’ Institute provides chess clocks and sets them up for the players.
Therefore, participants do not need to bring their own clock unless they personally prefer to have one available.
📺 Live Games
The organizer plans to broadcast the top six games on Chess.com with a 15-minute delay.
The direct broadcast link has not yet been published.
Players and spectators should check the official tournament page closer to the event for the live-games link.
🧾 Pairings & Standings
Pairings are posted on the wall inside the Chess Club.
The organizer also plans to update pairings and standings online when time permits.
Processed entries are expected to be published at least one day before the tournament, while final standings will be posted after Round 4.
🤒 Sick Policy
Mechanics’ Institute asks players who feel unwell to withdraw rather than attend the tournament.
The club reserves the right to refuse entry to a player who appears visibly ill.
A player who withdraws because of illness before the tournament starts will receive a full refund as credit to their Jumbula account.
🏛️ The Donaldson Tournament Tradition
The Donaldson Tournament is one of the recurring classical events in the Mechanics’ Institute calendar.
Mechanics’ Institute has described the event as unusual within its tournament programme because it is the club’s only tournament held in honor of a living player.
The tournament honors International Master John Donaldson, whose long association with Mechanics’ Institute and extensive contributions to chess in the San Francisco Bay Area form an important part of the club’s modern chess history.
👥 Capacity
The tournament is limited to 80 players.
Because the event is FIDE rated, centrally located, and divided into three rating sections, players interested in participating should register early rather than rely on the short on-site registration period.
🔄 Organizer Updates
Mechanics’ Institute reserves the right to adjust event details as the tournament approaches. This may include sections, time control, round times, or prize arrangements when changes are required to provide a better tournament experience.
Players should therefore check the official tournament page shortly before traveling:

♟️ About Mechanics’ Institute Chess Club
Mechanics’ Institute Chess Club is a historic chess organization based in San Francisco, California, United States. Founded in 1854, it is recognized by Mechanics’ Institute as the oldest continuously operating chess club in the United States. The club forms part of the Mechanics’ Institute, a nonprofit library and cultural center in downtown San Francisco, and operates from its historic building at 57 Post Street. Its fourth-floor Chess Room provides a permanent venue for tournament play, casual chess, instruction, lectures, and community programs.
The club maintains a particularly extensive program of US Chess- and FIDE-rated tournaments, scholastic events, chess classes, camps, lectures, quads, rapid and blitz tournaments, and community chess. Its signature competition is the Tuesday Night Marathon, a San Francisco tradition spanning more than 50 years. In addition, Mechanics’ Institute runs numerous memorial tournaments throughout the year and the annual San Francisco Scholastic Chess Championship, which brings hundreds of young players together for a free citywide event.
Alex Robins currently serves as Chess Director and is the principal contact for the club. He works with Christian Brickhouse, Chess Program Manager, Judit Sztaray, Head of Tournaments, and a larger team of tournament directors and coaches. The club’s active 2026 calendar continues with the Fall Tuesday Night Marathon beginning September 1, 2026, followed by monthly scholastic tournaments, quads, the St. Amant Memorial, Chernev Memorial, McClain Memorial, and a further Winter Tuesday Night Marathon later in the year.
📜 History and Chess Tradition
Mechanics’ Institute itself was founded in 1854, during the rapid development of San Francisco following the California Gold Rush. Chess became part of the organization from its earliest years, creating a tradition that has continued for more than 170 years.
The historic Chess Room has welcomed many major figures in chess history. Visitors and participants have included Emanuel Lasker, José Raúl Capablanca, Alexander Alekhine, Bobby Fischer, Boris Spassky, Anatoly Karpov, and numerous other leading players.
The original Mechanics’ Institute building was destroyed during the 1906 San Francisco earthquake and fire. The organization rebuilt, and its current Beaux Arts building opened in 1910. The Chess Room still contains historic chess tables and preserves photographs, records, newsletters, and archival material connected with generations of San Francisco chess.
This combination of living tournament activity and historical continuity makes Mechanics’ Institute unusual: it functions both as a modern competitive chess center and as an important repository of American chess history.
♜ Tuesday Night Marathon and Rated Competition
The Tuesday Night Marathon (TNM) is one of the club’s defining tournaments. Players compete in one classical game each Tuesday evening, allowing them to complete a full rated event without sacrificing an entire weekend.
The 2026 Fall Tuesday Night Marathon runs from September 1–October 13, 2026. It consists of seven Swiss-system rounds and is rated by both US Chess and FIDE. Players compete in three sections: 2000+, 1600–1999, and Under 1600.
The time control is 90 minutes plus a 30-second increment per move, and the field is capped at 120 players. The published prize fund is $2,400 based on 80 paid entries.
Each round is also preceded by a chess lecture. The Fall 2026 schedule includes GM Sam Shankland, GM Mark Heimann, IM Elliott Winslow, and IM Ladia Jirasek. Consequently, the TNM combines serious tournament play with continuing instruction from strong titled players.
Beyond the Marathon, Mechanics’ Institute runs monthly quads, scholastic Swiss tournaments, adults-only competitions, rapid and blitz events, and an extensive schedule of one- and two-day rated tournaments.
🏆 Memorial Tournament Tradition
Memorial tournaments form another distinctive part of the club calendar. Mechanics’ Institute regularly honors important figures from its own chess history and the wider Bay Area chess community through dedicated competitions.
The 2026 schedule includes events such as the Koltanowski Memorial, Peter Grey Memorial, St. Amant Memorial, Chernev Memorial, McClain Memorial, Benson Memorial, Capps Memorial, Shipman Memorial, and Donaldson Tournament.
Many of the two-day memorial events consist of four classical games and are submitted for both US Chess and FIDE rating. This recurring program gives Bay Area players frequent access to serious over-the-board competition throughout the year.
The club also maintains a substantial tournament archive containing results and records from previous events, preserving an important chronological record of competitive chess in San Francisco.
🎓 Scholastic Chess and Community Programs
Youth chess is a major part of the club’s current work. Mechanics’ Institute organizes classes, school-break camps, after-school programs, monthly scholastic tournaments, and coaching for young players.
The flagship event is the San Francisco Scholastic Chess Championship. The 20th annual championship took place on April 11, 2026, with a capacity of 300 K–12 players. The event is offered free of charge and brings together students and families from across San Francisco.
The club also brings chess outside its historic building through its Chess in the Community program. Regular public chess activities are held at locations including Mechanics’ Plaza, Union Square, UN Plaza, and Yerba Buena Gardens.
These programs make chess accessible to people who may never have visited a traditional chess club. Meanwhile, regular classes and competitive tournaments provide a pathway for those who decide to develop their skills further.
🌟 Grandmaster-in-Residence
American Grandmaster Sam Shankland serves as the club’s Grandmaster-in-Residence. Mechanics’ Institute announced his appointment in 2025, adding another high-level educational component to its chess program.
Shankland grew up in the Bay Area and has a longstanding connection with Mechanics’ Institute. He became U.S. Chess Champion in 2018 and has represented the United States in numerous Chess Olympiads.
As Grandmaster-in-Residence, he provides lectures, classes, office hours, simultaneous exhibitions, and other educational activities. In 2026, these have included public events as well as lectures connected with the Tuesday Night Marathon.
🏛️ Current Chess Team
Alex Robins leads the program as Chess Director. Christian Brickhouse serves as Chess Program Manager, while Judit Sztaray is Head of Tournaments.
The tournament team also includes experienced directors such as Scott Mason, Abel Talamantez, and Arthur Liou. Calvin Dees coordinates the scholastic program, while a team of coaches provides instruction for children and adults.
Together, this staff supports a year-round schedule that ranges from casual public chess and beginner instruction to demanding FIDE-rated classical tournaments.
