Trompowsky question...

I play the Trompowsky sometimes, and am wondering what's the best reaction for a Tromp player when black simply responds with 1.d5 instead of 1.Nf6? Thakns in advance.

You play the pseudo tromp instead with 1. d4 d5 2. Bg5 ?

Oh okay, I was thinking something maybe like 1 d4 d5 2. Nc3 Nf6 3. Bg5, but your suggestion is good as well. Do you know of any games online with that opening?

Your line would be my suggestion. That's called the Torre Attack

Nope sorry, I just know the opening exists. That's it.

It's the Levitsky Attack

In my opinion, the Veresov (1. d4 d5 2. Nc3 Nf6 3. Bg5) is a very inferior opening. Completely defies the principle that in d4 openings you should leave the c-pawn unblocked. I would suggest the Queen's Gambit instead. The Veresov opening, although playable, offers white very little chance of an advantage compared to the QG. This is why you don't see the Verasov at master level these days (If it has been played recently at a big tournament at master level please post a game or 2). Black can easily equalize with 3...c5!. Imo, you should play c4 against 2. Nf6 as well but this is just my opinion.

Against the Tromp, black can also play 2...c5!, when white's best move is Bxf6, giving up the bishop pair early to saddle black with doubled pawns. After exf6, black is fine anyways, the doubled pawns aren't too much of a big deal, I consider them as extra defense for black's kingside.

As you can see I am not fond of d4 openings w/o c4 but thats just me lol. (1. d4 (d5/Nf6) 2.c4 ftw )

Whoops. I thought you meant 2. Nf3. That would be the Torre

I kind of like the Veresov at times as a transposition with KID players.  1. d4 Nf6 2. d6 Nc3 (asking if they want to play a Pirc) d5 (2...d6 3. e4)  3. Bg5 (or 3. Bf4)

It depends on who is playing white.  Some players aren't going to be able to deal with every response black has to c4 and thus might be better served with a slightly different move order. 

 The Torre, as a whole complex, has a better pedigree than the Veresov.  But that's because it has historically had lots of high level support in the lines avoiding KID's and Nimzos.  1...Nf6 2...g6/e6 stuff.

Against 1...d5, the Torre is terrible, in view of the lines that continue 2.Nf3 Nf6 3.Bg5 Ne4.  These score overwhelmingly in favor of black, and make the Torre a nice replacement for the Trompowsky against Nf6 lines, if you favor a more positional game...but do nothing to help out against 1...d5.

Against 1...d5, a Tromp player is left with a difficult choice.

- Pseudo-Tromp, when black does have difficult lines he can throw at white, but which is a good practical weapon nonetheless.

- Torre, which is terrible against the line quoted above.

- QG lines, which are of course all good and well, but if the point was to avoid theory in the first place, well, that's out the window.

- Veresov, which isn't bad or anything, but is definitely anti-positional.

- BDG, which is, well, the BDG.

- London, which is dang unlikely to appeal to Tromposky players, unless you want to play a lot of lines where you gambit the b2 pawn.

- Some sort of Colle/Stonewall.  Ugh.
