The Colle-Zukertort System
Many beginners and intermediate players struggle with consistently following opening principles and navigating middlegame positions. I had the exact same problem until this opening provided me with a comfortable position and easy middlegame plans!
Setup:
This opening fights for the centre with 1.d4, and after 1...d5, we play 2.Nf3, developing our knight to the most natural square, adding more control to important e5 square - our main focus here, and what will motivate our play. The typical Colle system continues 2...Nf6 3.e3. Doesn't this break opening principles by blocking in our dark-squared bishop? Yes, so this is why we play the Colle-Zukertort system, and fianchetto it by playing b3 and Bb2! Our other knight goes to the d2 square, controlling the e4 square, but not stopping the c-pawn from pushing if necessary, with our light-squared bishop going to d3 also controlling the e4 square and aiming at Black's kingside. We castle kingside and aim for a same-side castling attack! Eventually, you will end up with the below position, showcasing Black's typical response.
Plans (into the early middlegame):
- Control the e5 square at all costs, as Black's main idea here is to push e5 to disrupt our centre and central control. This will often see us playing Ne5 to block the advance, and f4 to bolster it, adding even more control!
- Control the e4 square to prevent Black's advances, often ...Ne4.
- In the above position, if/when Black plays c5, we must instantly respond with b3 to prevent Black playing c4 which stops our light-squared bishop from developing to d3.
- To further prevent our bishop developing to this square, Black wants to play Nb4 - we play a3 prophylactically to prevent this.
Notice that if Black ever plays cxd4, we play exd4, maintaining our control of e5. Black will then attempt to generate counterplay down the semi-open c-file with Rc8, while we play on the kingside - we can always simply defend our c-pawn with Rac1 or advance it to c3 or c4 if necessary. To complete our development and start this kingside attack, we often play moves such as the rook lift Rf3-Rg3/Rh3, Qf3-Qg3/Qh3, and maybe even g4 to start a pawn storm!
With both our sniper bishops now aiming at the kingside, our knight centrally posted on e5, and our pieces positioned nicely on the kingside, every move we scan for sacrificial tactics around Black's king. More often than not, this is our favourite Greek Gift! In fact, in my first ever OTB game, I got this exact tactic - a quick walk around was needed to prepare myself for sacrificing like this in my first tournament game...
This was only the beginning! Yes, the knight can take, but Qh5 threatens checkmate, so the opponent has to give it back. Now up a pawn, and having weakened Black's kingside, I execute the plans laid out before. Look how the pressure on the kingside is far too much, and mate is coming! In this same tournament, I also won a game using these ideas, combining them with a kingside pawn storm. The engine gives the following position around equality, but practically, I prefer this for White as it is much easier to attack than defend.
The equality here comes from the fact that I didn't manage to stop Black's control of e4 - look how strong their knights would be on that outpost! However, the pressure got too much for my opponent, and I won just moves later.
It wouldn't be a legitimate post about this opening without giving credit to Susan Polgar for her amazing work on this opening. In the previous position, when I didn't know what to play, I asked myself 'WWSPD': What would Susan Polgar do? In reality, Susan would probably have played c4, but by thinking about model games I have seen, I was able to come up with a plan. I urge you to watch the below videos to gain a deeper understanding of this opening and all its intricacies!

I hope that this introduction to this amazing easy-to-play opening and the beautiful tactics it allows for inspires you to play it and no longer feel lost in the opening and middlegame. I will end this post with a thematic beautiful double bishop sacrifice:
