Losing a dominating position as White against Sicilian

[MikeGL]

While checking some Sicilian games, I happen to view one of the games of
SF8-Houdini6 and noticed a very weird game by SF8 where it lost from a
very good position. Credit to CCRL for this instructive game.

13.Nxc6 (maybe 13.g4! grabbing more space), 17.Qe2 (maybe 17.Qxd6), 21.cxb3 (21.axb3). The following is the specific positions of move 13, move 17 and move 21.

After 12...b4 of black, why did SF8 exchange with Nc6 when white has
so much space, exchanging just makes black recover from his space deficit.

After 16...Bh6 of black, why white won't capture the d6.

After 20...Qb5, SF8 played 21.cxb3 instead of 21.axb3, big difference.
In some top GM games cxb3 is acceptable once whites Kb1 is under heavy
fire, but not on this specific position.

Strange play by SF8, but good game by Houdini 6 too.

[yanquis1972]

SF-dev (as of october 17) would play the same game, unfortunately.

[Uri Blass]

SF-dev (as of october 17) would play the same game, unfortunately.

SF seems to need more time to find the right moves(at least axb3)
