что за бред?!
Sometimes Google doesn't provide accurate translations so I will help out with this one. The correct translation is the following:
"Dear developers of the site! What's the .....? In my game the opponent had made castling through a square that was attacked by my bishop!"
This is what the OP was talking about - nothing is about party and elephant. ![]()
Whenever I host a party, I keep my elephant around to punch my enemies in case they show up.
I suspect what happened in the OP's game is the opponent castled long when his (the OP's) bishop was attacking b1 (or b8). That's legal. The king can't move through an attacked square when castling, but the rook can.
