@photophore:

The ultimate 'book' on the Marhall: Tim Hardings CD "The Ultimate Marshall"  Smiley
has something on 18.Bg5.
It confirms your statement that this move hasnt been included in any book, and explains why:
there are no (grand)master games with this moves.
But the CD has at least a grandmaster opinion: (Vitomski) Quite a good move, but insufficient for an advantage.

Based on the info I cant agree with the conclusion that this should lead to the conclusion of a forced draw.
In the line you cite, black has a choice: either to take a perpetual or to go for a very unbalanced Knight vs Bishop endgame where black has a plus pawn...

The books are usually unreliable I am afraid - though I know nothing of this line I do know that much.

Yet , There is quite a difference between a drawish line ( what the Marshall is not ) and a forced draw , chiefly at white initiative
I usually play Open Defence but lately I scored 4 draws in sthe  uccession , then for once I tried the Marshall , as Aronian against Alekseev ( varsaw 2005 ) where was played the line with Bishop Sac
Moreover , Rybka find it in 10 sec , so I think it was in all "prepas"
Why the books tell nothing about it ?

Is Marshall old Main Line a forced draw ?

The Marshall "old Main Line" is :
1 e4 e5
2 Nf3 Nc6
3 Bb5 a6
4 Ba4 Nf6
5 O-O Be7
6 Re1 b5
7 Bb3 O-O
8 c3 d5
9 exd5 Nxd5
10 Nxe5 Nxe5
11 Rxe5 c6
12 d4 Bd6
13 Re1 Qh4
14 g3 Qh3
15 Be3 Bg4
16 Qd3 Rae8
17 Nd2 Re6
In this position ( I was Black ) my opponent played a move that is not  in the books (although it's in my DB )
Apparently , following moves are forced :
18 Bg5 Rfe8
19 Rxe6 Rxe6
20 Ne4 Bf5
21 f3 Bxg3
22 hxg3 Bxe4
23 fxe4 Rg6
And now after the natural and best 24 Qf3 ( in our game , my opponent played 24 Qf1 ?? and lost , but it's another story )
The draw is unavoidable
Does it mean that , if Black plays for a win  ,  The 17...Re6 variation is unsuitable , and should disappear ?
