1. Rxg1+ Qxg1
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.

You can only claim a draw on your own move. So I guess the question would be can black claim a draw by insufficient material after Ng3#. I would say no (obviously!). Also I'm not sure if you can ever claim a draw with KBKN, because it is possible to checkmate, but not force mate. Then same is true with KNNK. However when there's a referee or whatever you call them watching your game he can claim a draw in such positions (when forcing mate is impossible and there's virtually no chance of winning).
Originally posted by PeakiteI would have thought that black can only claim the draw when it is his move, and when it is black's move there is still too much material on the board to claim a draw. White could probably claim a draw instead of playing on for the win....
The position after two moves. White to move next.

Originally posted by PantaphobiaNot only is bishop & king against king a draw, king & 2 knights against king is a draw! Bishop & knight against king is a win though, although I suspect most people, including myself, cannot master the technique to do this in under the 50 move rule.
Thats my question for the chess masters to answer. when the only peices remaining equal a bishop and the kings, does this constitute a draw?
