When we sacrifice tactically - we usually want to get immediate advantages, like winning material back or reaching a mating attack against our opponent's King. The positional sacrifices have a different nature - they are real. By giving up a pawn, a piece or an exchange, we look for some compensation in the form of more active pieces, controlling key squares, open files, initiative, development advantage or opportunity of attack. A disadvantage of positional sacrifices is that there is no forced win and there are many possibilities and continuations, so the defender can suddenly spring a surprise and even hold on to the material advantage and win the game. That's why before a positional sacrifice you have to evaluate precisely many factors, giving yourself the opportunity to keep successfully a long term compensation. Positional sacrifice is always risky. Sacrifice only when you believe in yourself : even a correct sacrifice could become a wrong one if you step back in a decisive moment. In this new series of lectures with GM Boris we will study the most common positional sacrifices: pawn sacrifice, exchange sacrifice, piece positional sacrifice; and also the less common ones, like Rook and Queen positional sacrifices.
