- 15 Sep '05 17:43 / 1 editWhat I can see as a try is (since Black threatens to force perpetual check via 1...Rab2+ 2.K~ Ra2+ and so on) 1.Rxf7+ Kxf7 2.Rf8+ Kg7 3.b8Q! Rab2+ 4.Ka4 Ra2+ 5.Kb5 Rab2+ Ka6 6.Ra2+ Kb7 7.Rab2+ Ka8 and White should win. Alas 1.Rg8+ Kf6! 2.Rg6!+ Kf5! leads only to draw. How very unfortunate...

Hmm, I have a really good puzzle (found it in Kasparyan's "Remarkable studies" )

White has to capture both Black pawns without losing one of his pieces.*Originally posted by ilywrin***Hmm, I have a really good puzzle (found it in Kasparyan's "Remarkable studies" )**

Therefore it has to take them with knight and bishop or find a way to block them so the King can come to assist.

1. Nf4

a) if 1.. d4 2. Bf6

a1.) 2.. d3 3. Nxd3 Kc2 4. Nf4 Kd2 5. Bh4 e2 6. Ng2 Kd3 Kg6 7. Bf2 Ke4 8. Ne1 leading to a position that blocks the Black King so that the White King can come to assist.

a2.) 2.. e2 3. Nd3 Kc2 4. Ne1+ Kd2 5. Bh4 d3 6. Kg6 Kc3 (6.. Ke3 7. Bg5+) 7. Bd8 d2 8. Ba5+ (most tricky line)

b) if 1.. Kc2 2. Nxd5 Kd2 3. Nf4 e2 4. Ng2 rest like in a1

c) if 1.. e2 2. Nxd5 Kc2 3. Nf4 Kd2 4. Ng2 rest like in a1

If Black plays different it will allow White's king to get into the action.

So I guess the basic idea was to win the d-pawn first (except for line a2), then build a blockade with knight and bishop to prevent the e-pawn from promoting.

Well that was rather easy, so I'm not sure if it was all correct - 16 Sep '05 12:41

1.Rg8+!? Kf6 2.Rg6+!! Kf5! 3.Rg5+! Kf6 4.Rb5!! and wins.

As for the solution quite right, crazyblue. I'll post another one (this one is trickier):

White to play and draw - 16 Sep '05 14:13 / 1 edit

your solution is wrong, and Mephisto has provided me with 4 wrong solutions so far.*Originally posted by ilywrin***Now I have the haunting suspicion Mephisto may be right after all:**

1.Rg8+!? Kf6 2.Rg6+!! Kf5! 3.Rg5+! Kf6 4.Rb5!! and wins.

what if black plays 2. ...fxg6 ?

I don't think you both are grasping the point of the puzzle completely.
