Originally posted by mipmcptAlso, in the May 2006 issue of Chess Life, GM Susan Polgar's column discussed this opening in detail. The article was 4 pages long (which is twice as long as most of her columns) and discussed many variations within this opening. Anybody considering playing the Colle-Zuckertort [ECO D05] will almost certainly find the ideas presented in the article useful. Although I do not own the DVD, I would assume it covers the opening in even greater depth than the article.
also polgar has done a dvd on this variation!!!
I Like it a lot and play it frequently!!
Originally posted by KorchI then like 4.Bd3, if 4...Bxd3 then you have 5. cxd3 and a strong pawn center and a fun open c-file to use. if he doesn't play it, then he has to move his bishop, or defend, which wastes tempo
The main problem of Colle for white is that black can equalise easily after 1.d4 d5
2. Nf3 Nf6 3.e3 Bf5! (instead of 3...e6).

4...e6 is good of course, but in my opinion also 4...Bxd3 is playable - after 5.cxd3 white will have three pawns in center but this center is not too useful for offense as moving e pawn too far (or exchanging it) white doubled pawns d3 and d4 may become weak.
Originally posted by KorchAfter 3...Bf5, White should probably transpose into a Queen's Gambit with 4 c4 and play aggressively on the Queenside while trying to exploit the absence of the QB from that sector of the board.

If instead of 4 c4, White plays 4 Bd3, Soltis recommends 4...e6, as 5 Bxf5 exf5 will make it virtually impossible for White to expand in the center for quite some time.

Actually one of the ways to avoid 3...Bf5 is transposing into Colle after 1.d4 Nf6 2.Nf3 e6 3.e3 d5. Here is example from my own practice.

Originally posted by KorchYes, that is a very solid line. A bit more ambitious is 4...e6, and if White plays 5 Qb3, then Black plays 5...Nc6!. If White plays 6 Qxb7, then Black plays 6...Nb4!. After 7 Na3 (best) Rb8 8 Qxa7 Ra8 9 Qb7, Black can force a draw with 9...Rb8 or play for a strong attack with 9...Rxa3! 10 bxa3 Nc2+, etc.
After 1.d4 d5 2. Nf3 Nf6 3.e3 Bf5 4.c4 c6 it will transpose to Slav defence.
Originally posted by gaychessplayerAfter 4...e6 White should simply continue development with 5.Nc3 and I doubt if black has better option than to transpose into Slav with 5...c6
