In my testing, Komodo takes a lot longer than 00:22 to see this.

Well, throwing all your pawns at the opponent king.. SF would be so proud

Yes, that works very often in chess

After analyzing this I find Bf5 to be best, but from a testing point of view Kh3 is almost as good, and so it would be hard to use this position in a testsuite.

It's one of my favorites.
Castle opposite and storm the pawns. Not terribly effective most of the time, but always entertaining (at least to me).

Deep sacrifice. But how many cores does [Zubov2, Stockfish 150616 64] use at playchess?
