Pinned pieces offer more chances for opponent to maximise grip

Chess Checks

Pinned pieces are powerless pieces in a game of chess and hence all efforts should be made to get out of a pin as soon as possible. If a piece is pinned , then the opponent tries to exert maximum pressure by targeting it with as many pieces as possible.
In the game which follows, White’s rook is pinned but the crafty way in which White unpins himself and simultaneously poses a checkmating threat is exciting to watch.

10.Be2
A good move!
10...f5
Black is trying to steer the position to a sort of Dutch defence and in a previous game between Anand and Bologan the latter had tried 10...b6 11.Bg5 h6 12.Be3 f513.Qd2 Kh7 14.f3 Anand  was distinctly better 1

Black should have taken his King away from the dangerous diagonal and played 21… Kh8

This attacking advance was always in the offing

White is in a dominating position and Black has virtually no play
