Anti-Dutch 2 Bg5"

That's the thing.  I think both sides need to know the ins and outs of these positions, especially if Black wants to definitely use 1...f5 against 1. d4.  If Black isn't prepared, he can easily get crushed by these lines.  If he is prepared, then I think it is still playable for him.  As I mentioned before, we are essaying 2...h6 right now to see if we like it 

I am going to continue to look in the game database, maybe find some wins for White that involve some of the ideas mentioned.

A win by Malaniuk with the Black pieces after 1. d4 f5 2. Bg5 h6 3. Bh4 g5 4. e4 Nf6 (more of a mainline than Rh7!?) 5. e5 e6 6. exf Qxf with the bishop still trapped.  I am impressed with how playable he made the opening appear.

Here is an entertaining win for White after Bg3 and e3.  

I am hunting through the games, but if Black knows his stuff, it seems he has equal chances for a win.  I am more and more impressed with 2...h6 the more I look into it.  e4 definitely puts the test to Black, but otherwise, the game gives both sides chances to develop in a variety of options.  

hmm I'm Dutch so I should be good at this... but I always lose if I play it:(

lol renegade!

i play gambit 1.d4 f5 2.g4!

2. Bg5 actually poses little problem if you know the variation.

Just continuing 2..g6 3...Bg7 is sound enough but if you want to enter into the spirit of this trappy line then 2..h6 3...c5!? is very hard for White to navigate succesfully if he is a sub 2000 club player.

My Hopton attack lines (best play by both sides) are as follows:

2. Bg5 h6 3.Bh4

3...c5?! 4. e4! Qb6 5. exf5! and winning as the pawn on f5 is a dagger thru the heart of Black's postion he can't get rid of. If white can't find these two moves then the position is at worst very playable for black, and he has a couple of nasty traps in store against White as mentioned in McDonald's book.

3...g6 is also perfectly payable for Black as given in McDonald's book, but I prefer

3..g5!

A) if 4. Bg3 (hoping Black will fall into the f4 trap) then ...d6.

5 e4 leaves the Bishop getting trapped by ...f4 later in many lines - the ...Rh7 move mentioned above gives White nothing and he also has nothing after 5. e4 Nf6 6.e5 e6 7.exf6 Qxf6 8.Qh5+ Qf7 9. QxQ+ KxQ 10. Bg3 f4 11.Bxf4 g5xf4=

so 5 e3 is better but then Nf6 6.Nc3 Rg8 8.h4 a6 9.hxg5 hxg5 10.be2 Qe7=

B) 4. e3 transposes back into the above line after ...Nf6 5.Bg3 d6

C) the other thematic try is 4. e4 (actually played against me in my last but one Blitz game). Best here for Black is ...Bg7 5.Bg3 and then either fxe4 or d6 are fine for Black.

The Staunton (2.e4) is a much better anti-Dutch try as is deferring the Bg5 move until move 3 as in 2.Nc3 Nf6 3.Bg5 IMHO.

thx for your invation ..

It's a sexy line as white but as black I play 2...g6, and if white wants to exchange on f6 he'd normally need to trade off a couple of pieces at f6.  2.Bg5 has some nice surprize value, just prepare for both 2...g6 and the 2...h6 lines where black gains kingside space. 

Or, why not simply play the best Anti-Dutch 1.d4,f5 2.Nf3,g6 (though this isn't forced perhaps 2...d6 waiting is best) 3.h4!,Nf6 4.h5,Nxh5 5.Rxh5,gxh5 6.e4! with a strong attack and more than enough compensation for the exchange.  White at least maintains a slight advantage. 

  "I play gambit 1.d4 f5 2.g4!"

Not bad, but what about a preliminary 2.Qd3!? first?  2...g6 then 3.h4! 2...d5 then 3.g4!,fxg4 4.h3,g3! though I can easily see myself from either side of the board here, but only played from the white side so far since the Manhattan is quite rare.  Even then the Bogo-Nimzo Indian complex is my main defense vs. 1.d4.  Catalan players (I am sometimes) usually find the Bogo-Indian irritating, but the reason I play it is natural moves are typically good and plans clear. 

This is known theory, yes :)

 A team mate of mine lost a shocker as black a few years ago. The moves were something like:

He never lives it down as we remind him of it every couple of months !

Thanks for showing me more ways this diagonal being weakened can hurt.

The original post does look tricky. My moves may not be theory so look for better.

4. e4 is risky (for both sides), but there is still a lot to discover there.
