manudude03 Posted April 13, 2011 Report Share Posted April 13, 2011 hmmm call me blind, but I don't see how to checkmate in 2 if black plays b5-b4. Any other move he does and I see checkmate (c6-c7 then either promote to Q or take the pawn with your rook if he takes a5) Quote Link to comment Share on other sites More sharing options...
mattias Posted April 13, 2011 Report Share Posted April 13, 2011 White to play and mate in two moves. This is a cute one. Quote Link to comment Share on other sites More sharing options...
manudude03 Posted April 13, 2011 Report Share Posted April 13, 2011 ah, just ran it through a chess solver, so don't give me credit for it. I didn't think castling or en passent was allowed in these chess endings Quote Link to comment Share on other sites More sharing options...

gwnn Posted April 15, 2011 Report Share Posted April 15, 2011 I see it now too. Say you have the following position: White: Ba4Black: Kd1, Rb5, Bd5 This position occurred in a legal game (black to move), but unfortunately the white king fell from the table and everyone forgot where it was. Can you help? Quote Link to comment Share on other sites More sharing options...

Foxx Posted April 20, 2011 Report Share Posted April 20, 2011 White's last move was to capture a Black pawn. I have Raymond Smullyan's "Arabian Knights" book, which contains this puzzle and many others. Quote Link to comment Share on other sites More sharing options...

gwnn Posted April 21, 2011 Report Share Posted April 21, 2011 last hint: en passant capture warning, solution: initial position:White has:Kb3, Ba4, pc2Black has:Kd1, Rb5, Bd5, pb4 White is in check (black last moved his bishop and gave this check), so he blocked it with c2-c4. Black took it off, b2xc3. White took the pawn with his king. 1 c4 bxc3+2 Kxc3+ Quote Link to comment Share on other sites More sharing options...

blackshoe Posted December 20, 2012 Report Share Posted December 20, 2012 Hm. I don't remember - what's the definition of 'stalemate'? Quote Link to comment Share on other sites More sharing options...
Cyberyeti Posted December 20, 2012 Report Share Posted December 20, 2012 Hm. I don't remember - what's the definition of 'stalemate'?Stalemate occurs when a player has no legal moves, eg Black K on a1, black pawn on a2, white Q on the b file, black to move, game is a draw. 2 other related conditions. Zugzwang - where a side has to make a move that weakens his position so he loses Draw by repeat of moves - usually where the only move a side can make that avoids losing (or is the only legal move) leads to the position repeating (as the other side has nothing better) and when the same position occurs for the third time the game is a draw. Can occur in this position via Qc3: Kb1, Qb2+: Ka1, Qc3 etc Quote Link to comment Share on other sites More sharing options...
blackshoe Posted December 20, 2012 Report Share Posted December 20, 2012 Meh. It's been too long since I last played. :( Quote Link to comment Share on other sites More sharing options...
TylerE Posted December 21, 2012 Report Share Posted December 21, 2012 Great problem! Qc3 (Pinnging the b pawn) Kb1 (Forced)Qd3+ Ka1Qd4 (Pinning again) Kb1 (forced)Qe4+ Ka1 etc Until finally the Q gets to H8, and then on white's next move it's Qh1# Quote Link to comment Share on other sites More sharing options...
blackshoe Posted December 22, 2012 Report Share Posted December 22, 2012 Oh, now that's cool. Probably elementary, but cool. B-) Quote Link to comment Share on other sites More sharing options...
