GD Basquete de Leça – Xadrez is a chess organizer in Leça da Palmeira, Portugal. The chess section traces its activity back to 1977 and operates within Grupo Desportivo Basquete de Leça. Over time, it has built a visible role in local and national chess through club competition, regular events, and strong public tournament activity.

The organizer is best known internationally for the Leça Chess Open, a classical summer tournament that has become a recurring fixture in Portuguese chess. Its official materials also show a wider event structure, including classical events, rapid activity, and local competition under the GDBL chess section. In addition, the organizer links its work to player development and to the promotion of Leça da Palmeira and Matosinhos through chess.

The leadership side is clear as well. Raul Silva appears consistently as the main organizer-facing figure for the Leça Chess Open. Official regulations list him as the key phone contact, while tournament records identify him as tournament director. Pedro Soberano also appears as a public event contact, which shows a defined operational structure behind the organizer.
