I know you mean hxg3, I get the idea, Thanks, Alvin ----- Original Message ----- From: R Dinger To: blind-chess@xxxxxxxxxxxxx Sent: Tuesday, May 18, 2010 5:57 PM Subject: [blind-chess] Alvin, Re: Problem 21 revisited Hi Alvin, If Black plays: 1... Qxg3+ White will respond: 2. fxg3 winning the Queen. If Black tries the other approach: 1... Rxg3+ White uses the same reply: 2. fxg3 and the White Queen can now help defend the King. The only move that forces the White response is: 1... Qg2+ There is only one reply other than just resigning the game: 2. Kxg2 and Black follows with mate! Finding "forcing" moves is key to chess tactical play. And the very best forcing moves only allow one response--no surprises!

Qxg3+ 2. Kh1 Rxf2# With the discovered check from the Bishop on b7. It seems like a good solution. Alvin Hi Puzzlers, Ken asked about a possible additional solution to Problem 21 (the FEN and answer are reproduced at the end of this message). He wondered why Black could not play: 1... Rxg3+ as the first move instead of the posted solution. I think this is a good question and others may have the same or similar questions. Since this is a chess discussion list, maybe we should discuss the question. Would anyone like to comment on an answer to Ken's question. I have my own answer, but I will wait a bit to give mine. Problem 21: 7k/ 1bpp2p1/ 3bp3/ p4B2/ 2P5/ P3BrPq/ 1PQ2P1P/ 4RRK1 Points 4 Black ates in two. Solution: 1... Qg2+ 2. Kxg2 Rxg3#
