Can the triangle system be played as white ?

Against the anti colle (...Bf5) and QID formation ? Im not to interested in whites supposed "best try" or anything like that, I want to know if its playable and if against these options white still has hances to win (not againt perfect accurat play which would lead to a draw anyhow).

Is it possible to win with "x" against none perfect play? You're not interested in your play being optimal etc... Erm, yes? What exactly do you want from this thread? There is only one answer here. Of course it's possible, don't ask stupid questions.

when you put it that way it is indeed stupid but thanks got my answer :)

You can't play the Dutch as White.  You can play Bird's Opening, 1.f4, but that's not the Dutch.  Black has not committed to 1...d5.  The Dutch has the specific feature that e4 has been weakened.  1.d4 f5 controls e4.  1.f4, Black still has 1...d6 available.  This is why Bird's Opening is inferior to the Dutch Defense.  The Dutch depends on commitment from the opponent.

Same thing goes here.  There is no "Triangle for White".  After 1.d4 d5 2.Nf3 Nf6, 3.e3 is fine.  If Black plays 3...e6, you have a Colle System after 4.Bd3 and 5.c3 (Koltanowski variation) or 5.b3 (Zukertort variation).

Playing 3...Bf5 (or 3...Bg4) is called the "Anti-Colle" for a reason.  It makes moves like 4.c3 inferior, and Black has an advantage.  The Colle System depends on Black's Bishop being hemmed in behind the pawn chain.  Against 3.Bf5, causing the "bad bishop" to be "bad and active" instead of "bad and inactive" forces White to play more aggressively if he wants to maintain equilibrium.  Therefore, 4.c4 is needed, which happens to be a transposition to the "Slow Slav", but forget about opening names or theory, understand why White needs to do what White needs to do.  When he can play slower and when he needs to get in gear.  Pretend that theory and terms like "Slow Slav" don't exist.  Understand why White needs to play 4.c4 just from a positional perspective.

This is different than worrying about "best move".  After 1.d4 d5, the "best move" is 2.c4, but 2.Nf3 is fully playable.  This is where understanding the points behind the moves is more important than memorizing theory.  Understanding why 2.Nf3 is perfectly fine for White despite 2.c4 being the "main line" versus why the "best move" is 4.c4 after 1.d4 d5 2.Nf3 Nf6 3.e3 Bf5 is White's only real choice, and that 4.c3 actually hands the advantage to Black.

Thanks, that makes sence. 

I see thanks.

1.f4 d6 is interesting but is a sub line.

The main line, favoured by most top players, is 1...d5, curious isn't it?

That's just because like so many reversed opening, black is ready to go for it, opting for a reversed dutch which is not a big deal for white anyway...

Some sound logic this is...

You think that the most commonly played response to 1.f4 at all levels is so bad, that playing it with the free added bonus that White is forced to forfiet his next move is still worse for Black than if he had played something else?

You ******* idiot.

Part of it also is that it's not like move 1 is magic and the rest is useless.

The problem can also occur at move 2, 3, 4, etc. 

In reverse openings, White often has a problem at one of the moves in the opening that Black doesn't have because often that decision is determined by what the other player commited to first!

White has the advantage of going first, but White also has the disadvantage of having to commit first (Black can answer 1.Nf3 with 1...Nf6, equally non-commital, then even 2.g3 g6 3.Bg2 Bg2 4.O-O O-O and now White must decide whether to play b3, d3, d4, etc., before Black has to make any such decision.)

As mentioned in my response to poucin, move one is not the only move you have to worry about committing first.  It goes on in subsequent moves.  So if you still answer 1.f4 with 1...d5, White still must commit first before you make latter decisions, like g3 vs e3, etc.

And the only ******* idiot is YOU, ChessOath!  I hear your mommy calling you.  Go to her, see what she wants.  I can hear her now - she's in the bedroom!
