Re: A case of carrying on past checkmate

It could be said that capturing the king is something that never gets a chance to happen, rather then something specifically forbidden. Likely, way back at the beginnings of chess in early 6th-century northwest India, the game did go on to capturing the King, but there was something semi-divine abou...

Re: Let's swap pieces instead of wearing out openings

Of the 6 possible arrangements of R N B on the king's side, the official arrangement is the only arrangement where foolsmate (1. f3 e5; 2. g4 Qh4#) works.

A case of carrying on past checkmate

A few days ago I was playing chess with a friend. His king was on the edge of the board. I checkmated him with my queen guarded by my knight. He, feeling tired, played KxQ, leaving himself in check. I also felt a bit tired, and played NxK and claimed win.
