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.
Interesting q. Get somebody to set up the pos (can't start when under check) and see if you can claim the draw.

Good idea Ragnorak, created as an open invite if anyone is around and willing to play.

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).

I 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 question is can it be claimed after Bxg1.

I have the position set up in open invites if you wouldn't mind playing to that position.

I answered that question above.

Erm, no you didn't.

Anyway, maybe an open invite wasn't the way to go. If anyone is interested in playing that position send me a message and I'll challenge you to the game.

You can challenge me. And I don't understand how I didn't answer your question. Please tell me. By the way white could just play 1. Ng3 but I realize you wanted to reach the specific position.

It's just after Bxg1 the point is there is insuffient material then, and as RHP seems to work is that the draw is claimed in conjunction with a move.

I can't actually challenge you at the moment - I'm below 1500.

Done & cheers

And for everyone, for the record it ignores the claim for the draw.

Not 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.
