The King from CM9000 sees the winning move instantly, but it takes 0:47 to announce mate in 14. I waited 5 minutes and it only improved to mate in 12.

Re: White to play and checkmate in 9 moves.

Post by Ajedrecista »

Hello:

An amazing problem once again! This one toying with stalemate and knight checks over almost all the first rank of white king walk. Superb.

I would push the question a bit more, resulting in a long post. I analysed the following position with SF 16 (NNUE enabled), single core and without Multi-PV:

1.- Kb1, Nd5; 2.- Kc1, Nb4; 3.- Kd1, Nd5; 4.- Kf1, Nb4; 5.- Kg1, Nd5; 6.- Kg1

[d]8/4p1Rp/4pk1P/3np3/4P1p1/B2P2p1/3P2P1/6K1 b - - 11 6

Code: Select all

FEN: 8/4p1Rp/4pk1P/3np3/4P1p1/B2P2p1/3P2P1/6K1 b - - 11 6

I do not know if it is a matter of null move or whatever, but SF takes a while to solve a checkmate in three moves (six plies) with only six moves to consider (Nb4, Nb6, Nc3, Nc7, Ne3 and Nf4), with five of them leading to a checkmate in the next move (Bxe7#).

------------

Was not it enough? Same conditions after playing 6.- ..., Nb4, clearing hash and restarting the engine:

Less time for this five-ply checkmate, though depth 50. o_O

------------

It take less and less time after each played move, still very high depth and solution time. The same experiment as before after playing 7.- Kh1:

Black has only six moves to choose again, with all but one leading to checkmate just after. Four-ply checkmate and depth 32!

Three-ply checkmate and depth 33... there was a slight regression in the final countdown! Then, black moves its knight wherever and the checkmate is there.

------------

Just to get an idea of how much blind or stuck SF is, I computed perft(n) of the former positions and compare with the number of nodes needed to get the correct checkmate evaluations, where n is the number of plies until checkmate:

Code: Select all

=========================
n   perft(n)    SF nodes
=========================
6   824,551    66,470,219
5   114,276    24,015,299
4     6,846    10,045,262
3     1,403     9,398,910

SF gets Kb1 M9 within a few seconds
But is you leave it up to 15 minutes it still will not find all the 9 wining moves :roll:
Yes it does:
