I have the CCC archives, but there is a big hole in them, since the ftp site has
not been working for some time. Anyway, it sure looks to me like Ke3 is also a
solution. Can someone refute this move sequence, or show me a perpetual check
or some other escape? It looks to me like black is simply toast, and rather
quickly at that!
Position after Kb3:
[D] 8/k1b5/P4p2/1Pp2p1p/2P2P1P/1K6/3B4/8 b - -
[Event "?"]

[Date "????.??.??"]

[Result "*"]
[FEN "8/k1b5/P4p2/1Pp2p1p/2P2P1P/1K6/3B4/8 b - - 0 1"]

I am assuming that the capture of the pawn is the serious mistake here.
So we are left with these possibilities:
[D]8/k1b5/P4p2/BPp2p1p/2P2P1P/1K6/8/8 w - - acd 13; acn 5549434; acs 8; ce
32754; pv Bxc7 Ka8 Ka4 Ka7 Ka5 Ka8 Bd6 Ka7 b6+ Ka8 b7+ Ka7 b8=Q#;
[D]8/k7/P4p2/BPp1bp1p/2P2P1P/1K6/8/8 w - - acd 13; acn 4356112; acs 7; ce 32754;
pv fxe5 fxe5 Bc7 e4 Ka4 e3 Ka5 f4 b6+ Ka8 b7+ Ka7 b8=Q#;
[D]8/k3b3/P4p2/BPp2p1p/2P2P1P/1K6/8/8 w - - acd 17; acn 39893138; acs 60; ce
32746; pv Bc7 Bf8 Ka4 Bd6 Bxd6 Kb6 Kb3 Ka7 Bc7 Ka8;
[D]k7/8/P2b1p2/BPp2p1p/2P2P1P/1K6/8/8 w - - acd 16; acn 39567322; acs 61; ce
1051; pv b6 Bb8 Ka4 Ba7 b7+ Kb8 Kb5 Bb6 Bb4 Bc7 Kc6 Bd6 Ba5 Ka7 Kxd6 Kxa6 b8=Q
Kxa5;
[D]5b2/k7/P4p2/BPp2p1p/2P2P1P/1K6/8/8 w - - acd 16; acn 40283136; acs 60; ce
2534; pv Bc7 Be7 Ka4 Bd8 Bxd8 Kb8 b6 Kc8 b7+ Kd7 b8=Q Ke8 Qc7 Kf8 Qe7+ Kg8 Qe8+
Kg7 Qxh5;
[D]1k6/8/P2b1p2/BPp2p1p/2P2P1P/1K6/8/8 w - - acd 16; acn 39792421; acs 60; ce
1379; pv b6 Bxf4 Ka4 Bg3 Kb5 Kc8 b7+ Kd7 a7 Ke6 a8=Q Kf7 Kxc5 Be5 Qd8;
And only these two are slightly viable.
[D]1b6/k7/P4p2/BPp2p1p/2P2P1P/1K6/8/8 w - - acd 19; acn 36613753; acs 62; ce
435; pv Bd2 Bc7 Kc3 Kb6 Be3 Bb8 Kc2 Ba7 Kd3 Bb8 Bd2 Ka7 Ke3 Bd6 Ba5 Bf8 Bd8 Bg7
Bc7;
What about this one?
Then Kc3, and does black have any choice besides ...Bxf4 or ...Bd6 (both of
which are answered by Bd8)?
[D]8/k7/P4p2/BPp2p1p/2P2b1P/1K6/8/8 w - - acd 19; acn 36253857; acs 60; ce 388;
pv Bd8 Be5 Kc2 f4 Kd3 f5 Ke2 Bd4 Bg5 Bb2 Bxf4 Bf6 Be3 Be7 Bg5 Bd6;
This second one, is debunked carefully below:
}
3. Bd8 Bd6 4. Kc2 Bf8 5. Kd3 Bd6 6. Bxf6 Bg3 7. Ke3
Bd6 8. Bd8 Bh2 9. Be7 Kb6 10. Bxc5+ Kc7
*
{
Black is hopelessly lost at this point.
}
Is there a way for black to close the door on this formation? I surely don't
see it.
