Positional Pawn Sacrifice Buries Black’s Bishop

Sacrifice Fails without 8.h4h5

This is one of the most important chess concepts you’ll ever learn to improve your middle game. Combine it with an active opening repertoire, and you will soon become feared by your opponents.

The Value of an Exchange

Black has a huge advantage in space and in the center.He's behind an exchange but at least equal.

White takes time to exploit a dark square weakness early in the game. Black responds by sacrificing the exchange for quick development and dynamic play. He initially plays well, but fails to target the right weakness at a key moment. This allows White to consolidate, simplify the position, and the exchange suddenly becomes decisive.

Play on both sides of the board

Play on both sides of the board

In Pawn Structure Chess, the tension between two pawns is called a “lever.”  Very few things dictate the nature of a contest more than how the player handles this tension.

Chaos and an overextended knight


Do a general survey of the key ideas before you start analyzing a specific variation in great depth. On many occasions, I have spent a great deal of time and energy, looking six or seven moves deep in a certain variation, only to find I missed something simple and better way back at the beginning.

Classic Sicilian Counterplay

white's position is hopeless

Play in the Sicilian is typically sharp because of the imbalanced pawn structure. It’s especially important to pursue the right plan in sharp positions, because it can be difficult to contain your opponent’s counter play, and he will often take over the initiative after a couple of small inaccuracies.

All-out Struggle for a Key Square

All-out struggle for a key square

Black makes a critical error on move 14, and tries to organize a defense with his king in the center. Both sides focus their attention on the d5 square. The square falls, and Black’s king must run for cover. In the meantime, White wins additional material and he enters an ending with a two pawn advantage.
