I am playing a game (4316794). The game is 89 moves into it. My oppnent has a King, Knight & Rook. I have my King. We have made 55 half moves since last capture/pawn move. When or does an automatic stalemate take effect? Don't have much more room to run, :'(Game 4316794

"Stalemate" occurs when the player whose turn it is does not have a legal move. This is an automatic draw.

You may claim a draw if there has been no capture or pawn move for 50 full moves (100 half-moves). This is not automatic - you have to claim it. You've got another 45 half-moves to go yet.

You can also draw if the same position is repeated 3 times (also not automatic and has to be claimed).

The 50-move rule doesn't need the full history. The number of non-pawn/non-capture moves is at the end of the FEN, so is available as part of the current state of the game.

There may be a problem with claiming a draw by repetion, though.

Getting back to the original query - stalemate is when no legal move is available. For example if you only have your king left and capturing or moving it puts it in check,
