Day 17 Part 2 - Study Strategic Problems from Strategy 3.0
After Day 17 Part 1 I continued to study (Theory) strategic problems.
I learned about the following:
Chess Strategy 3.0 Course
Positional Sacrifice
— Positional sacrifices, which have nothing to do with forced variations, and based on intuition and containing an element of risk, were called "real" by Rudolf Spielman, compared to "imaginary" sacrifices, whereby consequences may be precisely calculated.
—One can often come across a sacrifice of a piece for a few pawns in order to create an active pawn mass.
—Exchange sacrifice is more sophisticated positional trick and is done for such reasons as: play on squares of a certain color; Seizure of a strategical important point; destruction of the opponents pawn structure, etc.
—The aim of a pawn sacrifice may be: opening of a file; vacation of a square; activation of pieces; slowing down development of the opponents forces, or weakening of squares of a certain color, etc.
—Amongst positional sacrifices one can come across a Queen sacrifice. The Queen is usually traded for a Rook and a light piece or two pieces and several pawns, counting in the future on activity of the pieces fighting against the Queen.
Below you can see examples of all the problems I Solved:
