From one of Stefan Pohl's LTC games. Stockfish 9 seems really reluctant to play Komodo's move exf6 here (allowing Bxh2+):
[D] 2kr2r1/pbqn1p1p/1p2pn2/3pP1p1/P1pP1b2/2P2Q2/1PBN1NPP/R1B2RK1 w - - 0 15
But Komodo 11.01 gives this move a + score even with a relatively shallow search.
Komodo wound up with 2 Knights vs Rook and 2 pawns, and won the game:

Re: interesting Komodo-Stockfish eval difference
Komodo is really good at material imbalance. Since Larry wrote the inaugural paper on the subject we should not be surprised.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Are the evals available too? IMHO 22...e5! should at least hold for Black and it seems White was a bit lucky here.
