A nice study.
Forced win for black, where a N defeats a Q.
Thanks for this position.
I also checked with critter at Multi-PV==2, critter just shows 0.00 for both Nc8 and Ng5+
I told my wife that a husband is like a fine wine; he gets better with age. The next day, she locked me in the cellar.

Very fine one, Dann, where did you find it?
Zugzwang arises not before 5th move, so even switching off nullmove by UCI- option doesn't help quickly, (e.g tried with komodo), yet 2MV mode does the trick as for SF.

Gave it three trials, each one about as fast as that. 24 threads of 3x12GHz, 8G hash.

What if I change the start position in simple way?
Maybe, I can't be friendly, but let me be useful.

Now, first a sacrifice 1 Rxe5! fxe5 and next 2. Nc8! insted of 2.Ng5+
MonteCarlo and multiPV can't help to find 2.Nc8.
Very clever, Marek!

Well, at least it is statistical pruning, meaning the case doesn’t arise often enough in real life to matter, as ani rating list kno
RL NN’s statistical beings that they are, possibly won’t kno either. Funny if AB’s and RL-NN’s both will fail to lern tha same stuff.
I hope that authors of THE AI know that such side statistical questions can lead to pruning: man... people... humanity?

Well, I don’t about that, but clearly hard pruning or even not so hard pruning is vulnerable to tail events.

Very fine one, Dann, where did you find it?
Zugzwang arises not before 5th move, so even switching off nullmove by UCI- option doesn't help quickly, (e.g tried with komodo), yet 2MV mode does the trick as for SF.
I found it in the Rybka Forum. Someone there with the handle dorszcz has been posting interesting chess problems for the last few days.
Here is my current analysis record for that position:
8/1p1pNpbk/1q1P4/pP2p2K/P3N3/4P1P1/3P4/8 w - - acd 66; acs 1275; am Ng5+; bm Nc8; c0 "
http://rybkaforum.net/cgi-bin/rybkaforu ... ?tid=32840 "; c3 "Nc8"; ce 1568; pm Nc8; pv Nc8 Qd8 Ng5+ Kg8 Ne7+ Kf8 Nh7+ Ke8 Nd5 Qb8 Nc7+ Kd8 b6 Kc8 g4 e4 Ng5 Bf8 Nxf7 Bxd6 Nb5 Bc5 Na7+ Qxa7 bxa7 Bxa7 Nd6+ Kd8 g5 Bb8 g6 Bxd6 g7 Bb4 g8=Q+ Kc7 Qd5 Kc8 Kg6 Kc7 Qxe4 Kb6 Qc4 d6 d4 Ka7 e4 Ka8 Kf6 Ba3 Qg8+ Ka7 Qd5 b6 Qc6 Bb4 Qc7+ Ka8 Qc8+ Ka7 Qc6;
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
