Moves with questionable uniqueness

[Hobacle]

Finally I decided to create a separate thread to collect those moves. For example:


[fen]8/2k5/3p1pK1/3PpP1n/1p1pBp2/1PbP1P2/8/B7 w - - 2 4[/fen]

Is 4.Bb2 the only drawing move here?

[Hobacle]

[fen]4k3/4Pp1Q/3PpP1P/1Kpp4/P1B4P/5p2/RP1qnPr1/5nr1 b - - 0 2[/fen]

Is 2...Rg8 the only drawing move here?



[fen]5q2/1K2ppNp/7k/P6P/8/3N2P1/BB6/5n2 w - - 0 1[/fen]

1) Is 1.Be6 the only winning move here?
2) Is 2.Ne5 after 1.Be6 Ne3 the only winning move?

I don't think so, Crystal says:

Analysis by Crystal 5 KWK:

1. = (0.00): 4.Bb2 Ng3 5.Bc1 Ne2 6.Bb2

2. = (0.00): 4.Kxh5 Kd8 5.Bb2 Bxb2 6.Kg6 Ke7 7.Kh5

3. -+ (-#20): 4.Kf7 Kd7 5.Kg6 Ng3 6.Kxf6 Nxe4+ 7.Kg7 Ng3 8.Kg6 Ke7 9.f6+ Kf8 10.Kg5 Bxa1 11.Kh4 Kf7 12.Kh3 Ne2 13.Kg2 Nc1 14.Kf2 Kxf6 15.Kg2 Nxb3 16.Kf1 Nd2+ 17.Ke2 Bc3 18.Ke1 b3 19.Kf2 b2 20.Kg2 b1Q 21.Kh2 Qe1 22.Kg2 Qf1+ 23.Kh2 Nxf3#

But probably it's missing some cyclic Zugzwang again

BTW, fen- icon does not work again right now. [d] syntax is created by it using the icon after submitting, regards

I got the same result from my computer, but it isn't enough to prove a draw or a win. 2...Qb4 line leads to a NNvQ endgame with some pawns, which is too deep for me. Since 2...Qb4 is the only possible move other than 2...Rg8, maybe we can start from 8.axb5 in its line.

My main concern is 1.Be6 Ne3 2.g4 . After 2...Nxg4 3.Bxg4, the BBNNvQ endgame seems winning for White from my pov, although Black has some extra pawns.

Edit: if you read my text here before, sorry, I was simply to stupid for your studies once again and couldn't delete it anymore, just edit, but about my first suspicion, that could be a matter of cyclic zugzwang again, I yet was right, wasn't I?

Not quite sure but probably yes (2.Ne5 winning only) too, regards

My main concern is 1.Be6 Ne3 2.g4 . After 2...Nxg4 3.Bxg4, the BBNNvQ endgame seems winning for White from my pov, although Black has some extra pawns.

This time you might be right, even if Crystal went out of time in reversed game coming too near to 50 moves rule and game got adjucated drawn.
Same pairing and hardware- TC like with second one position, this time started from 1.Be6 Ne3 2.g4 Nxg4, both games of reversed colours in one .pgn:

Not quite sure but probably yes (2.Ne5 winning only) too, regards

My main concern is 1.Be6 Ne3 2.g4 . After 2...Nxg4 3.Bxg4, the BBNNvQ endgame seems winning for White from my pov, although Black has some extra pawns.

This time you might be right, even if Crystal went out of time in reversed game coming too near to 50 moves rule and game got adjucated drawn.
Same pairing and hardware- TC like with second one position, this time started from 1.Be6 Ne3 2.g4 Nxg4, both games of reversed colours in one .pgn:

This is sad... Although the main line is 1.Be6!! fxe6 2.Nf4 Qd8 3.Nf5+ exf5 4.Bg7+ Kxg7 5.Ne6+ Kf6 6.Nxd8 Nxg3 7.Ne6!!, the side line 1...Ne3 2.Ne5 fxe6 3.Bc1! Kg7 4.h6+! Kg8 5.Bxe3 Qf5 6.Nc6 is still cool. But this side line seems cooked now.
