Yes. And I didn't check if the three PVs include transpositions and might converge to a common future position ...
It's always fun when the first two moves are just swapped, but the evals are different (though differences tend to be small).

Yes, seen that many times. In this case, the three PVs seem distinct, after a (not so careful) review.

I've never seen Komodo show the same score for 2 different lines. I think it has some special code to have transposing lines score the same, and non-transposing lines score differently (so maybe that third move shown has really a -1.12 score, but Komodo subtracts a centipawn to avoid showing no preference on the moves.) It's funny when you do that in MultiPV=4 and you get 4 lines equally strong but each one has 1 centipawn difference from the above one because of this (unlike Stockfish that could show them with the same score so what move to investigate is left to the user.)

Komodo has proven useless both at defending the Grob or attacking it, so I wouldn't pay attention to its moves or scores. But this is Komodo 11, perhaps 2 versions later it became amazing!

No way! I'm willing to offer x100 win odds (you get one win, it counts as if you win 100 times in a row) to whoever thinks they can beat me with 1.g4 :D

FWIW, 13...h5 was not one of Komodo's top 3 moves at depth 48 after 30 hours of searching with MultiPV=3.

Ethereal 11.88 to depth 34 prefers h4 too, with a suspiciously low eval of -0.81. It would never hold this position against Stockfish.
Neither would Komodo, apparently! :mrgreen:
