(and that's why I'm spending so much time making "sure" that doesn't happen. but who knows how low Zenmastur has gotten that mate to)
FWIW, my Stockfish-dev is now showing Mate-in-29. At depth 92. Haven't attempted to guide it to something lower, and won't be doing that.

Re: Pls help a poor beginner, Moves generator

Your ply 3 is also wrong. Read about perft/divide to debug. Stockfish can give numbers from a command line, like this: position fen 1rb2r1k/3p1pp1/p3p2p/1p2P3/4q3/1N2B1R1/PPP1N1P1/2KR1B2 w - - 0 1 go perft 6 a2a3: 48375495 c2c3: 45116632 a2a4: 54745564 c2c4: 47626243 b3a1: 47021849 b3d2: 40586189 b3...

Re: Plaskett's Chess Puzzle Solved in ~15 minutes

Waiting already 6 minutes in depth 33 now without solution, don't know, how long I'll let it run. Stopped after 20 minutes without solution. At least McCain is rather good in Backwarding the lines after the Queen-sac, which isn't so for all engines, even modern ones, neither. E.g. komodo does bette...

Re: mmt Vs. Ovyron (G4 D5 BG2)

The very reliable fastgm has mate-in-30 . If you're within 5 of that, I suggest you return to the game with mmt. Your "fans" are growing restless. Oh boy, you may have ruined everything if Zenmastur disqualifies me for getting "outside help" :cry: I'll see what he says about this (knowing in advanc...
