Just out of curiosity, what would happen in a position like this (both on RHP and OTB). Which if I'm correct white has a forced mate, but blacks last move means there is technically not enough material on the board.
Not exactly a common occurence by a long way (and maybe there is a line other than the obvious here). But a question anyway.
Edit: I've realised it wasn't forced (I'm not good at that sort of thing), this maybe? Moving the white knight on e2.
Originally posted by PeakiteI don't fully understand the question. White's in check so has to choose between taking the black knight or moving the king.

But, in a position like this, the moves have to go ahead until there are not enough pieces to force a result.

2. Rxg1+ Bxg1
It's now N v B, but
3. Ng3#
But could black claim a draw after his second move? Which given my experience of the three time repetition rule, I've claimed on the move which creates that situation. So if that were applied here, it'd be drawn.
Originally posted by PeakiteN vs B is a draw. There's insufficient material and neither side can mate. You can even give away a piece and it won't make a difference.

Originally posted by ark13I think in a tournament the TD's would look at the position before declaring a draw due to insufficient material. I would hope this site wouldn't give a draw with a mate in 1 situation at hand. Doesn't a 'higher-up' review the game when you try to claim a draw?
But there's a checkmate in one move. Could the draw be claimed?
What I suppose the issue comes down to is whether the draw is claimed on mate not being possible, or it not being possible to FORCE mate.
I once had a game where I had R vs B,N + 3P but the pawns were doubled H pawns and a G pawn, but I was able to sack my rook for a knight, forcing a recapture with the G pawn leaving tripled H pawns and the wrong colour bishop (what are the odds!?) which was drawn... would I be allowed to claim this as a draw if I had such a position on the site?
Also what happens in the case of K+2N vs K? Does the person with the 2N should be allowed to play on for the 50 moves to try and get his opponent to blunder into a mating net, or can the draw be claimed immediately?
