Difficult endgames

[Jouni]

The latest matefinder at http://chess.ultimaiq.net/stockfish.html is definitely worse than december version! But who has done it and where is all info??

[Nordlandia]

37...Qe4 is winning according last stockfish dev ultimaiq bmi2.

However, it is interesting to see how engines will play out this engame with the sub-optimal move 37...Kf7 (second best move according stockfish). The advantage is still -1.10 in black's favour.

There is hope for this endgame

Ponder: ON

Black: i7-5690X 4.1GHz | 8-Core

Obviously this game should be taken with grain of salt (hardware imbalance).

Jon, that the Black advantage is big enough to let a weaker hardware lose at 15'+15" doesn't mean anything. I saw lose SF with White at equal hardware against SugaR and against Houdini at 240'+30" 12 cores each.

In your game there are some suboptimal moves right from the start, I guess.
Latest but maybe not quite too late, after Forward- Backward and 7.f4 (?):
