latest dev-McCain, similar to SF, takes a very long time to find Ne5:

Good one again!
And once again, as for komodo, you just have to raise Dynamism just up to 200 (125 default, 400 max.):

One out of three trials, each <150" to stay stable on solution with 24 threads of 12x3GHz, 32G hash, no tbs.

As for SF, "TacticalNew"10 (0 Default, 100 max.) of "RomeoA23"-setting works about as fast too.

H6.03 got it default at three trials each <61", two times <15", so it's best one out of the 3x3 engine-trials, I had till now.

The position that most intrigue me was at move 21 for white:

Thanks for the game. Maybe SF had eval term that tells it to avoid further piece exchanges if down in material. White is down 2 pawns here and if eval of SF had this term then this could be its strength as well as its weakness.

I once peaked at Crafty eval module and found also that Crafty won't simplify if it is down in material. That 21.Ne5 move is difficult because it allows further material exchanges while down in material, which is a NO, NO for GM's and even mentioned in Nimzovitch's My System and also in Capablanca's Fundamentals of Chess.

Should've listened to Lyudmil, French is lost for black. But i honestly still love to play the French as black.

latest dev-McCain, similar to SF, takes a very long time to find Ne5:

BTW, as you'll probably have found out with McCain by yourself too, the position shows well the meaning of contempt as for SF- search.

CFish with Contempt 21 (default) and White Analysis Contempt checked, after just 105 seconds, in depth 29, started with empty hash in 8MV- mode, hardware as desribed in the other posting.

This was the slowest of three trials, best one was 50" and depth 27. At each one the engine kept solution stable onwards with eval constantly climbing.

None of a few more trials in 8 MV mode was nearly as quick with Contempt 0.

Of Kaissa based on Stockfish 10 sourcecode, only the latest experimental version can now find 21. Ne5 {!}, but it takes half an hour on one thread. Stockfish I think misses something in the eval, so search has to do it all alone. Then, if the engine finds g4 first, it gets a little harder because that is about 0.7 pawn. It is probably just a draw so not really an alternative. The idea behind g4 is not so hard but it seems to be total random if a version finds it or not, which is also not what you want really. Strange, I think Stockfish also does not see g4.

Possible PVs from a version that only sees 21. g4:

best move: g3-g4 time: 1145:03.141 min n/s: 1.842.265 nodes: 126.569.359.508

No 21. Ne5 is ever found. Sometimes at the beginning, but only as a draw line with 21. Ne5 Nxe5 22. Qxe5 {?}

Version 43 can find it but it is probably a lot of luck. It extends quiet singular moves for a change (Extending quiet moves, even if only singular ones, is something you want to be careful with (unless they are singular so you know they are good at the moment (until the extension fails). Extending them doubly is I think not done in any sane engine

Because it may explode search to extend more than ONE_PLY, and is pretty costly in nodes searched relative to tactical exchanges, which you almost never reduce except in Probcut and at the very leaves sometimes (the benchnumber with this almost doubles, but that is to be expected with an extension that is often triggered). In this position it pays off

Stockfish I think misses something in the eval, so search has to do it all alone. Then, if the engine finds g4 first, it gets a little harder because that is about 0.7 pawn. It is probably just a draw so not really an alternative. The idea behind g4 is not so hard but it seems to be total random if a version finds it or not, which is also not what you want really. Strange, I think Stockfish also does not see g4.

Possible PVs from a version that only sees 21. g4:

No 21. Ne5 is ever found. Sometimes at the beginning, but only as a draw line with 21. Ne5 Nxe5 22. Qxe5 {?}

Version 43 can find it but it is probably a lot of luck. It extends quiet singular moves for a change (Extending quiet moves, even if only singular ones, is something you want to be careful with (unless they are singular so you know they are good at the moment (until the extension fails). Extending them doubly is I think not done in any sane engine

Because it may explode search to extend more than ONE_PLY, and is pretty costly in nodes searched relative to tactical exchanges, which you almost never reduce except in Probcut and at the very leaves sometimes (the benchnumber with this almost doubles, but that is to be expected with an extension that is often triggered). In this position it pays off

Today, I got it down to 15 minutes with one thread Kaissa. Version 068 with search_030

. I don't know if it is really better but at least score would be higher than in the output above. And it relatively quickly finds that c5 is just a draw after Qa5. Does not find g4 though.
