@shoopi Very nice!
And here's one composed by me:
My own composition also has notation (check the "move list").
If you want I can explain the other two.
In the first puzzle white is down a rook for a pawn, so obviously he's looking for a draw. His only chance lies with the pawn.
As they say, "passed pawns must be pushed". For the first move, white has the option of pushing his pawn with tempo on the rook, so clearly that is the only move.
In the second puzzle white has only one path to victory, which is tricky indeed!
I have noticed an unfortunate problem with the second study, which I rather liked.
In the line 2.Rc4 bxc4 3.Bxc3+ Kg8 4.Bb2 instead of c3 black can play cxb3 5.axb3 a5! with the unstopable threat of a4, with the black king easily reaching the queening corner and white having the wrong coloured bishop drawing
@Retrodanny: He was first puzzled, because he was very surprised that someone said that the shortest connection between two points is not a line. Then he asked me to explain my point more precisely and when I told about the walk of the king, he said that that is chess in which movements are made in squares, not in points. A line is a collection of points. But if you see those squares as points, then can you see that it is still a line.
@varelse1: wow, that was a talented class!
Hey. thank you very much for posting these endgame puzzles!
@oran_perret sorry I should of been more clear, a4 can't be stopped in time, black doesn't play it immediatly on move 6 which would lose as you said because he can't get back to stop the a pawn queening, instead black gains the required tempo first for instance 6. kf2 kf7 7.ke2 ke7 8.kd2 a4
White is helpless to avoid the draw, either the king moves towards the pawn or bishop alternates on c1-a3 diagonal. Either way black has the requried tempos to get within the square of the passed a- pawn and is ready to push a4 which can't be stopped in time.
I should also mention i've now checked this analysis with the computer, which agress with what I thought
I managed to discover how to create a new diagram, shame about the position, but never mind
andy, that's a fair point, and good catch.
I tried to find the tactic again from the site I originally got it from, but I couldn't find it. It is possible that is was deleted due to your line
