To be fair, Morozevich gives 9...bxc6 as the main move in his According To book with 9...exf2+ as an alternative in brackets, although admittedly he does think the latter also leads to an edge for Black.
Bronznik only covers ...exf2+.
Wisnewski in 1...Nc6! doesn't cover the line, presumably on space grounds as he has played it as Black.
The bottom line is that gxf3 seems to be a good improvement over Kxf3 in the ...exf2+ line. Unless a counter-improvment is found, Black is definitely better off with the counter-intuitive ...bxc6.

Even though he endorses 9...exf2+, Morozevich played 9...bxc6 in an actual game unfortunately Wink
Thanks for the suggestion 22...Rgd8, that looks like a good way to fight for equality. But you seem to agree that
the theoretical evaluation of "slightly better for black" is incorrect.

Nice! a pity you didn't play Morozevich with White, he would have been embarrassed after the perpetual Smiley. At the position you give, perhaps Black can play 22...Rgd8 and push the d-pawn to untangle, it is humble but probably enough to keep balance. At least, White doesn't seem to be winning on the spot.

The other day I lost a game as Black with the Chigorin straight from the opening (to my mind).
The line is supposed to be slightly better for black, but I don't see it! What am I missing?

1.d4 d5 2.c4 Nc6 3.cxd5 Qxd5 4.Nf3 e5 5.Nc3 Bb4 6.Bd2 Bxc3 7.Bxc3 e4 8.Ne5 e3 9.Nxc6 exf2+ 10.Kxf2 bxc6 11.e4 Qxe4 12.Bd3 Qf4+ (=/+, Morozevich)

a game Bonin-Wisnewski, ICC 2000 went
13.Qf3 Qxf3+ 14.Kxf3 Be6 15. Be4 Bd5 (=/+, Bronznik)
but my opponent played 14.gxf3! and from here on I feel I played nothing but forced moves:
13.Qf3 Qxf3+ 14.gxf3 Ne7 15.Rae1 Be6 16.Rhg1 Ng6 17.d5! cxd5 18.Bxg7 Rg8 19.Bb5+ Ke7 20.Bd4 a6 21.Bc5+ Kf6 22.Bf1
and black is struggling.
Fortunately black can deviate earlier: 10...Qxc6 or 9...bxc6 or 8...Nxe5.
What do you think?
