Komodo frittered away a couple of endgame edges, but still looks to be the class of the field, even on 1 cpu.

Not sure about the piece sac/loss here (move 22), but Equinox claimed a large advantage (+1.25) before that, but then Black was up by about -2 around move 38 or so. Then both sides felt they were ahead by almost a pawn for a bit (move 53-57 or so).. After 61. Nc3, Equinox says +1.77 --- it is certainly true that in the long-term pieces will dominate a queen, with weak pawns playing a key role. Sjeng finally admits White is superior (and significantly so), and Equinox is now at +2.71. As usual, these material imbalances are a major bone of contention between engines.

At a practical level, Black can try to exchange off a few more pawns and then maybe hope for NN vs P with a 50-move draw, though White should be able to avoid this. White's progress will likely be slow in any case (constantly trying to avoid queen checks, for instance), so it might be a good test as to whether an engine can win these kind of endgames.

Another "imbalance" game. Booot has managed to pull out a draw, it seems. Equinox was claiming an advantage of 2.5 at one point.
