When you mean to say the Trompowsky Opening, that is d4 Nf6 / Bg5, that is not an attack yet.
The Torre Attack is d4 Nf6 / Nf3 e6 / Bg5 -- or d4 Nf6 / Nf3 g6 / Bg5 -- or d4 Nf6 / Nf3 b6 / Bg5, in these cases a real attack.
Btw, this Attack is named after Mexican Carlos Torre Repetto (1905-1978) and not after Filipino Eugenio Torre (1951)
Your question is whether Bg5 is better than d4 Nf6 (Indian Defence) and than e3 or e4 at some time...? Please complete your question !
I am thinking about using the Trompowsky Attack for white I am currently using the King's Pawn. Also, If you have anything better than the Trompowsky or you think I should stay where I am please advise.
Thanks!
