Maybe someone should inform Naumov.

8/4B3/8/1k6/3p4/3K4/8/2n5 w - - 4 116

In this position, Naum 4.2 played Kxd4 and immediately claimed draw by sending
"1/2-1/2 {Insufficient material}" to ChessGUI.

ChessGUI penalized Naum with a loss becaused a checkmate is theoretically possible.

Naum ran as UCI engine. Though the UCI protocol does not support claiming a draw, some UCI engines claim draws anyway.

Was ChessGUI wrong to penalize Naum ?

I have a brilliant idea with the side effect that you guys may wait one hour or longer for an engine move that may never be played.
ChessGUI shall optionally allow UCI engines to play on after they declare "end of game" by claiming a draw. Some engines can play on. Those that cannot, will keep you waiting till they lose on time.
"Optionally" means the GUI operator shall decide.
