Maybe play ...Na5 if you have the knight still on c6, or if White plays a5 after having a pawn on b4, play ...a6?

The precise move order is to play a4-a5 first and if Black reacts with ...a6 to follow up with b4-b5 anyway. In a rotationally symmetric way it's the same for Black at the other side of the board. Lines must be openend and then the better placed pieces decide. The tricky thing is to insert a defensive move at exactly the right point. Dom is right: delaying castle (Nge7, f6) to keep White guessing can gain one or two important tempi.

I play the ooo in the Exchange. The a4-b4 pawn roller gains in force against this line when light square bishops are not exchanged.

That's why the best strategy is to use the "delay castling" trick..to let not White use this attack. Useful to remember too are the basic ideas of the good (for Black) exchange of light square bishops and the defence over the greek sacrifice Bxh7.

1.e4 e6 2.d4 d5 3.exd5 exd5 4.Bd3 Nc6!? 5.Nf3 Bg4 6.c3 Bd6 7.oo Nge7 (a little better than the obvious Qd7  Burn-Spielmann,1912)  and now here are some lines vs pawn roller

Years ago, after having experienced trouble myself with the 0-0-0 line, I examined quite a few games and came to the conclusion that some players preferred to castle long only if White had done a weakening move (such as .h3) on the kingside.

I try to go to the stucture (if allowed) Nbc6, Bd6, Nge7, f6 Bg4, Qd7 and OOO. Then continue with g5-h5-g4. It is risky indeed but white plays exchange typically to avoid this type of doubleedged positions only. My 'practical' results are very good.

The thing with opposite castling is that it's more risky, so you only can expect to get into a little trouble now and then.
Usually best is x.b6 cxb6 y.axb6 a6, but that invites a sack on a6 indeed. Now White does not have that many options for this sac (the King's Bishop or a Knight on b4) so it makes sense to hinder such piece arrangements. Also don't forget to make progression with you own attack. After all it takes White at least five moves to play b5-b6.

Moskalenko gives a line where Black exchanges the light square bishops and queens (Bg4-f5, Bxd3, Qf5), after which it becomes a positional fight.

I think the big problem is the pawns arriving on a5 and b5. Castling queenside seems quite risky to me in the Exchange Variation, even if you are trying hard to win castling kingside is still usual.

Hi, I usually try to castle 000 in the Exchange variation. The thing is now and then I get into a little trouble. It when white has pawns on a5 and b5, pushes to b6, and if I take, sacks the pawn by pushing to a6 and opens his a-file. Sometimes on b6 I play cxb, and when white takes back, play a6, but it seems like that sets up a sack.

Maybe theres some standard chess rule on how to defend against this type of attack or my fellow French defence players can give me some advice here.

Thanks.
