ResponderExcluir1 Bb1!! 1-0
ResponderExcluir1 ... c4?? 2 Qd4#
1 ... d5?? 2 Bb8#
1 ... Kd5?? 2 Qe4#
1 ... h5 2 Nb4!!
(2 ... cxb4/c4 3 Qd4#)
(2 ... d5 3 Bb8#)
Well done, Jake! 1. Bb1!! is the key move.
ResponderExcluir1. Bb1!! c4
2. Qd4#
1. Bb1!! d5
2. Bb8#
1. Bb1!! Kd5
2. Qe4#
When Black replies with 1. ... h5 I chose 2. Bc2!! as my second move:
1. Bb1!! h5
2. Bc2!! c4
3. Qd4#
1. Bb1!! h5
2. Bc2!! d5
3. Bb8#
1. Bb1!! h5
2. Bc2!! Kd5
3. Qe4#
But 2. Nb4!! also works, as you have showed:
1. Bb1!! h5
2. Nb4!! cxb4
3. Qd4#
1. Bb1!! h5
2. Nb4!! c4
3. Qd4#
1. Bb1!! h5
2. Nb4!! d5
3. Bb8#
2. Bd3!!, 2. Bg6!! and 2. Bh7!! would also work.
I have composed this three-mover by myself, so I would like your opinion: was it a good one? Could it be better? :)
Technically it's valid, as its key move is unique (in other words, there's only one possible key move). The issue I have with it is that there are so many different possible second moves that work (granted, all of them except for the knight move share a common theme, but whatever). I think the next three-mover you compose should make sure that there's only one second move that works, or, if there are two or more, that they share a common theme.
ResponderExcluirTruth be told, I saw the knight move before I saw any of those bishop moves. I saw that 2 Nb4 completely immobilizes the king, so I went with that. Plus, I like sacrificial moves A LOT.
ResponderExcluirThank you for your analysis and tips, Jake.
ResponderExcluirI am a beginner in this chess composing world. So, I still have a lot to learn.
For this problem, I was trying to compose a two-mover, when I realized a three-mover was just ready. :)
Next month I will try to come up with another problem, 2- or 3-mover.
You're probably a better chess composer than I am; I completely SUCK when it comes to composing chess problems (though I'm fairly decent at solving them XD)
ResponderExcluirJake, you are indeed a very good solver of chess problems. And I really appreciate all the attention you give to my efforts.
ResponderExcluirI'm already working on my next problem. I hope I can finish it soon. :)
