Kundenrezensionen Love Science? You can watch a video describing the Colle-Zukertort here. In short, it is a set of chess moves designed to constrict your opponent, so you can orchestrate a massive kingside attack. You can safely play it against almost any Black setup, but serious players will want to build up an opening repertoire around it. The author does not assume you are a world-class player. You can now play 1.

This opening strategy is ideal for people who do not want to lose a game on move 8 because their memory failed them while, at the same time, allowing White to gain a significant advantage if Black missteps.

Before getting started, I want to point out that the C-Z is not a single opening solution you should lazily play against everything the rest of your life. You can play it against pretty much anything and not come out worse, but eventually you need to learn how to deal with pet defenses Black can throw your way. You can learn the mainline of the Zukertort in literally 15 minutes and safely play it against practically anything, but then to get the most out of the opening you should sew it into a larger chess repertoire.

Luckily, there are books that show these solutions to help you do that. The basic structure of the Zukertort variation is shown below. He has options as to where he puts his pieces, but the above pawn skeleton is more or less forced. You might ask why. The answer comes down to the e5 square. White has three men hitting that square, so Black has a hard time pushing his e-pawn past e6.

Thus, Black typically will fianchetto his Q-Bishop to b7 playing Bd7 ends up causing a lot of problems for Black in general, see my video on the Zukertort on this page. The pawn on a3 may seem curious. That pawn is principally designed to keep a Knight off b4, where it would hit your Bishop on d3. If Black develops his Q-Knight to d7 instead of f6, there is little danger of his and White generally would not play a3.

If Black instead plays his Q-Bishop out to f5 or g4 before pushing his e-pawn to e6, things typically become rather sharp, but as I mentioned earlier White can still safely play the C-Z setup, it just is not optimal — More of a comfortable option until you find time to learn the structures and themes of those lines. If Black fianchettoes his K-Bishop by playing …g6 and then …Bg7, then White will generally want to play something other than the Colle System.

There are various solutions given for this. However, you can still play the Colle System without feeling like you are already behind. If you do, I would recommend playing your Bishop to e2 instead of d3 and either playing for Q-side space or castling Q-side and throwing your K-side pawns up the board.

Note this latter option is purely a practical-play consideration. Do not consider it a solid repertoire solution if you are playing an important game with someone about elo. Black typically pushes his c-pawn to c5 in all Q-pawn games, and in the C-Z it is particularly important because the Q-side is generally the only place he will get any hope of play. That explains the skeleton I showed above. What typically occurs is that Black exchanges on d4 to open the c-file and White puts his Knight on e5 and supports it with f4, leading to the setup shown below.

Note how the central pawn mass is pretty stable. Since White has not played c4, there are no exchanges or advances that can be done to dissolve the blockade.

Black also has a difficult time defending his King because his space is all on the Q-side. He can have problems transferring his pieces because there is a bit of a bottle-neck in the center of his position. Nf3 d5 3. Once he has followed suit, deciding his Q-Bishop is going to stay on his Q-side, there are far fewer ways for him to mix things up. Bd3 c5 Now that Black has opened up his K-Bishop, this pawn is supported. In truth he could have played it on move 3 or even move 2, but obviously those plays would require him to have a bit more confidence in understanding the outcome since the pawn has no immediate defense.

The point of this move is to stop …c4 which would harry the Bishop on d3. O-O c4. The Koltanowski is named after George Koltanowski who championed the c3-version of the Colle for over half a century. In the Koltanowski version, White plays 5. Bc2, and his Bishop is still on a good square. O-O Bd6 This is the most testing play.

It might seem that 6…b6 is smarter since the Bishop is going to go to b7 anyway. Thinking about it that way makes …Bd6 seem overly committal. The issue is that once Black spends a move on …b6, it is very hard for him to mix things up in the center. It more or less allows White to complete his intended setup without any tactical concerns.

Bb2 O-O Arriving at a crucial position below: From here White typically plays 8. Nbd2, but Black has a tricky way of dealing with that move. I originally suggested 8. Ne5 here, leading to a very interesting attack after 8…cxd4 9. After 11…Nxd3 Qxd3, White has the threat of Rh3 followed by Ng4! However, as much as I love that attack, it is not impossible to defend against. If White wants to get the absolute greatest advantage as I showed in a chessville article , he needs to play 8.

However, that requires White to have a good grasp of many different kinds of positions. If you are a quiet player willing to get a comfortable position where your opponent has to know exactly what to do even to get equality, then it is the move for you.

Nbd2 This stops Ne4 Bb7 Ne5 And now White can comfortable launch a K-side initiative. I have placed a board with the first moves in it below so you can play through them. Zukertort Wisdom Some general guidelines for playing the C-Z: 1.

Never allow Black to place anything on a3, f4, or e5. Often, Black retreats his Knight from f6 to dislodge your Knight on e5. That is often the critical time to attack. Keep a pawn on d4 unless you are beginning, or have already begun, your attack on his King. Stronger players who know what they are doing after dxc5 can ignore this. If your opponent dilly-dallies, just continue to train more men on his King.

Do not attack too early. If Black moves his K-side pawns or transfers a Knight to g6, use a pawn or two to help your pieces attack him. Otherwise you can probably attack with just your pieces. More downloads and information can be found on the Zukertort download page.
