Isolating a piece

GM Dorian Rogozenko writes: "Today's lecture deals with the strategic idea of isolating a piece. Everybody has heard knows about isolated pawns, but much less is known is the concept of playing against a piece, usually knight or bishop, but sometimes even the queen, until it is completly isolated. I will start with classical examples and then show how grandmasters use such ideas in modern tournament practice. Moreover there are some opening variations in which the main strategical idea is to play against a specific piece and try to isolate it from the main battle field that will arise during the game. All in all this is an interesting strategical subject, little studied, but very effective in the practice."
