Is there a way to punish 1. d4 c6?

This is not a bad trap, though 5B:b5 is a mistake., & either 5Nd2 or even 5f3 (i don't like 5Bd3 because of ...Nc6) is perfectly all right.  As Black, i like to play things like 1d4 c6 2e4 Na6! because of 3B:a6 Qa5+. 

Yes but after 3.c4 (IMHO this is the best move) what do you play? 3...Nc7 with the idea of d7-d5? I guess white has a space and a development advantage, and black has no compensation, though I never played this opening.

This is a whole opening system called the de Bruycker. Black usually fianchettos his King's bishop., & pushes d5 later if at all.

It's interesting, it reminds me of the Pirc in which black sometimes plays Nb8-a6-c7.

In the game on #20 with the trap, it's first principles not to swap a centre pawn for a wing one. I would play 5. Bd3 and ask black whether black has anything worthwhile or is losing. The position could be reached from an Alapin Sicilian move order where black has played the weakening b5.

No no, black has played c6, not c5, and so 1. d4 ...c6 2. d5 immediately hands black the advantage. White isn't even level.

d4 c6? , e4

c6? is a move solid , extremly defence and VERSATILE but solid

no , you can't punish c6?

1.d4 c6 2.e4 d5 is the Caro-Kann, one of the most solid openings in all of chess and an opening championed by several World Champions.

why did you put c6 with a question mark?

is 1. d4 c6 2. Bf4 Qg6 pointless?  Just respond b3 and be done with it, or is there Qxb2 poison pawn trap opportunity?  Or Vaganian maybe?

I think you mean Qb6. It seems off to me- black tries to nab some pawns with his queen on move 2. Nd2 should offer compensation or Qb1 will work too. 

b3 is a so-so move, but since black isn’t developed it would be ok

You can transpose to the Caro-Kann or the Slav but if you really want to punish it you can play a London System where Black's c6 is almost useless and he would much rather play c5 instead

What about

1. d4 c6

2. Bf4 Qb6

3. b3 is the obvious move, but database has just a few instances and white wins none.  What's best way to monopolize the center?  Is this a Vaganian Gambit:

3. Nc3 Qxb2

4. Bd2 Qb6 attack d4, or d5

5. e4 or f4 to gobble center -- or Rb1 trap Q?  I don't see how to make that happen

3.Nf3 is also obvious. I wouldn't like to take Black after 3...Qxb2 4.Nbd2 - way to many tempos for a measly pawn.

3.Nc3 is much worse, first because the knight cannot jump to b5 and second because you will have to move the Bf4 again.

No, there isn't something special. White may try playing either a London system proper, or 2.Nf3 followed by Bf4, e3 and c4, since a QGD formation  with ...c6 is slightly passive against this setup. But even like that, it's nothing important.

Still, I fail to see WHY Black should start with 1...c6 instead of the natural 1...d5. I can't think of a way to gain something.

to avoid the London !

How the heck you avoid the London with 1...c6?

Here, Bxb5 is wrong. By first principles, you don't swap a centre pawn for a wing pawn unless there's a gain from it. If you aren't going to play e4 followed by Bd3 then an alternative good setup for white is 3. cb ...cb 4. Bf4 ...Nf6 5. e3, which also gets an advantage no matter what black does. But I prefer the straightforward plan with e4.

Maybe a better plan for white is 3. e4 (or perhaps 3. e3)

by delaying the d7-d5 pawn push forever

That doesn't avoid the London System. It just means Black will play a setup against it that doesn't involve ...d7-d5.

If black can get h6 and g5 in that setup then that's not the London !

I suppose the way to go is into the Caro-Kann Fantasy Variation. Since I know how to play against the Veresov-Richter with 4. f3, I would probably know what I was doing, since I used to use a variation with 4. ...c6. Many others wouldn't have a clue and it could be good for 1. d4 players to study it and occasionally bring it out against 1. d4 ...c6.
