11...Bf5 has been the accepted move, but I suspect things are far from simple there - Shirovs way looked very effective, if only for a draw - but your not going to get much more than a draw anyway with best play in the Marshall

What you may not realise is that Moro v Shirov Moscow was a last round game where absolutely nothing was at stake. I'd say Shirov was simply holding back  for another day

11...Bf5 may well equalize, but there is a lot of play in that position, basically Black has to be careful about Whites general plan to mobilise his kingside pawns with f2-f4-f5. I know there are some positional threats of Black also but I dont believe White is in serious dangers here, although he has lost it before - I think Anand played a game as Black where he mobilised the queens rook with the plan ...a5,...Ra6-g6, another theme to watch.

Marshall 9.d4!?

Some months ago I decided to abandon the King's gambit in favor of the Ruy Lopez.
One line that attracted me was 9.d4!? against the Marshall attack.

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 d5 9.d4!?

Now Shirov gives his game with white against Bacrot on his DVD on the Spanish.
In the game Shirov developed an attack after 9. ... ed4: 10.e5 Ne4 11.cd4: Bg4 12.Nc3 Bf3: 13.gf3: Nc3: 14.bc3: f5 15.Kh1 Na5 16.Rg1.
I like this kind of position for white.

In his comments Shirov also says that black can equalize with 11. ... Bf5.
But the games I have seen with 11. ... Bf5 suggest that black has the better chances after that move!
He exchanges the light squared bishops and after Nc6-a5-c4 and a5,b4 blacks attack on the queenside seems faster than white's play on the queenside.
Check out Bacrot-Anand, Corsica 2004 for example.

But in the game Morozevich-Shirov, Moscow 2006 Shirov chose to play 9. ... de4: 10.Ne5: Ne5: 11.de5: Qd1: 12.Bd1: and eventually drew the game, though perhaps white was slightly better.

So the question is if white has an improvement against 11. ... Bf5, or why else did Shirov avoid it??  Huh
