3. Feudenheimer Sommer Open runs from August 21-23, 2026, in Mannheim, Germany. This is a chess tournament in Mannheim, Germany, in 2026. It offers a compact late-summer classical weekend in the Feudenheim district and brings players together in one open field with a clear five-round structure.

The event uses a five-round Swiss system and a classical Fischer time control. Moreover, it counts for DWZ rating, so it suits club players who want a serious rated weekend without a long festival format. The published cash prizes reach EUR 980 if all listed prize categories qualify, which is approximately USD 1,125 at the current ECB reference rate.

The tournament takes place in the Spielsaal DJB Steuben Feudenheim at Neckarstraße 22a. In addition, the venue offers practical local access because tram line 2 stops at Neckarstraße, while drivers can use the free parking area at Spessartstraße. The published player limit is 60, so early registration matters.

📌 Event Details

⏱️ Time Control & Pairings

The tournament runs over five rounds with a Swiss system. Each player receives 90 minutes for 40 moves, then 30 minutes for the rest of the game, with a 30-second increment from move one. Meanwhile, the organizer seeds the field by the latest DWZ from the DSB database, and the event is rated for DWZ.

The rules also include a clear electronics policy. Therefore, players may carry devices such as phones or smartwatches only if they switch them off completely during play.

🏆 Prize Fund

The published cash prize list reaches EUR 980 in total, which is approximately USD 1,125. However, several youth and rating prizes require at least three players in the relevant category. Because of that, the fixed overall prizes for places 1-5 total EUR 720 (approx. USD 827), while the full published payout applies when all listed categories qualify.

The organizer applies the minimum-participation rule to the category prizes. Therefore, each category needs at least three players.

👥 Sections / Groups

This event does not split the field into parallel sections. Instead, everyone plays in one open tournament, while the organizer adds separate prize categories for youth players and several DWZ bands.

🗓️ Schedule

📝 Registration

The organizer asks players to complete both registration and payment by the published deadline to secure the lower entry fee. In addition, the event page notes that the room capacity is limited, so the 60-player cap matters in practice.
