Stockfish won with black:
after 20.Rae1 its black Q vs. B+B+pawn;
20...Nxe6 pawn for exchange sacrifice;
23...exd3 capturing 2 pawns instead of taking the knight on a8;
26...Rxf4 exchange sacrifice to remove the c1 defender;
27...Kb8 declining the N on c7 to keep its c2 pawn;
after 28...Qd1 it is Q and 2 pawns vs. R+R+N, then black wins 2 more pawns and the game. [Event "AMD PhII X6"]

Interesting, I like these kind of openings.

The consensus is that it's not enough compensation for white in the initial position. White has to fight for a draw at best.
