Tactical Motif of Rook Sacrifice at the Corner of the Board by GM Nadezhda Kosintseva
Some experts suggest that solving puzzles is the best form of study for the purpose of improving tactical skills in chess. But for me, it only attacks the problem from one dimension. You can solve a variety of chess puzzles, but if you do it chaotically it will not really help you to recognize a tactical pattern in a real game. Personally, I believe that systematization of tactical patterns and creating one's own classifications of chess combinations can seriously improve one's technique of calculation. Thus, in this lecture I am going to show you how the separation of the tactical motif of rook sacrifice at the corner of the board from other types of sacrifice helped me to be more precise in the process of calculation.
