Well, that certainly wins the prize for the deepest mate announcement ever.
And certainly, it is a mate in 2,724 or less (plus it has the right key move)

This didn't occur when I ran Crafty-23.2 from the command line. See here. Maybe a GUI bug?

Good thing Bob doesn't work for Microsoft, or that would be a feature :D. Maybe it was fixed in 23.2. Kinda cool, though. It's not every day you see something saying Mate in 2724 :P.

I'll try command line later.
I'm off to eat dinner. I'l let crafty running under the (Fritz12) Gui tackle this for an hour or so. I am using wb2uci, if this explains anything.

On this run, (fresh instance of the Engine and GUI) it found the mate in 12, in 3:08, however, some bug reports the mate as 2,744

Re: Only BUP wins

Post by David Dahlem »

Another game where only a bishop underpromotion wins:

[D]8/8/5b2/8/K7/8/kp6/3N4 b - - 1 63

Boniface - Pugh
Bristol 1995
Black had to play 63...b1B, because 63...b1Q or b1R 64.Nc3+ Bxc3 would be stalemate. Although the position was then technically won for Black, he did not manage to win, and a draw was agreed at move 92.

Naum 4.2 doesn't think the win is easy, while Stockfish 1.6.3s does.

Naum 4.2:

35/44 05:23 575.725.171 1.782.430 -1.76 b2b1B Ka4b4 Bb1g6 Kb4c4 Bg6f7+ Kc4d3 Ka2b3 Kd3e4 Kb3c4 Nd1e3+ Kc4c5 Ke4f5 Bf6c3 Ne3g2 Bf7a2 Ng2f4 Ba2b3 Nf4e2 Bc3a5 Ne2f4 Bb3d1 Kf5e4 Bd1c2+ Ke4e3 Ba5b6 Nf4h3 Kc5d5+ Ke3f4 Bb6d4 Nh3g5 Bc2g6 Ng5f3 Bd4c3 Kf4g5 Bg6e4

Stockfish 1.6.3s:

Well, that certainly wins the prize for the deepest mate announcement ever.
And certainly, it is a mate in 2,724 or less (plus it has the right key move)

It probably should have been 27.24 and the decimal was just left off. Just my 2 cents.

Sure, but how do you make .24 of a move?
