3/20/2026 – After the Prague International Chess Festival, the top players didn't want to stop playing, so they set up three boards for 6-player bughouse. World Champion Gukesh, Keymer, Maghsoodloo, and Ganguly were joined by rising "futures" stars Clio Alessi and Lilian Schirmbeck to create absolute chaos. Keymer was basically overpowered the entire game, while Ganguly held on with everything he had. The highlight? A ridiculous loophole battery where they sacrificed 10 knights and bishops in a row. Finally, no engines, no prep. Just pure fun between some of the best chess players in the world.

What the heck is a 6-Player bughouse?
Regular bughouse is 4 players on 2 boards, paired into 2 teams. When you capture a piece, you hand it to your teammate on the other board, and they can place it on any open square on their turn instead of making a normal move. It's fast, loud, and chaotic because you're constantly shouting at your partner for pieces.
6-player bughouse takes that to 3 boards, with 2 teams of 3. Captured pieces get passed along the chain to a teammate, so there are now more boards feeding pieces into each other. The result is exponentially more insane. Pieces are flying everywhere, coordination between three players is nearly impossible, and the whole thing devolves into beautiful madness.
With three boards feeding pieces, someone can just keep sacrificing knights and bishops because they're instantly being replenished from the other boards. It's like an infinite ammo glitch in a video game.
