Pinned Pawns

Recently in ICC blitz games, my opponents have had a rash of pinned pawns that allow me to win a pawn. Perhaps they've always been there and I'm just noticing them now that I'm intensively focusing on tactics.

I'm not claiming that grabbing the pawn was the best move; Fritz tells me it wasn't, but it was definitely there, it was definitely a good move, and in every case, having seen it, I took it.

If this is the result of tactical study, then let me have more tactical study!

Look for pinned pawns. Easy points for the taking.

This would accomplish two things: (1) it would make the Black knight on a6 look rather foolish, and (2) it would hinder the pawn break c5. Of course, I don't defend it, but move it. 16.b5 Nb4 17.bxc6 bxc6 18.Bd2 Nxc2 19.Qxc2 Nf5 20.Be3 Rfc8 21.Rfb1 Ba5 22.g4 Nxe3 23.fxe3 Diagram # The issue here is Black's pawn break, c5. This may well be THE issue for positions with this pawn structure: support and execute the pawn break. 23...Qa7 A move that indicates a deeper understanding of the position than I had. Specifically, Black realizes that the issue here is supporting and executing the move c5. The draw back of his move is that it neglects White's g5 pawn push. As such, Qe7 was called for, supporting both c5 and defending g5. 24.g5 hxg5 25.Nxg5 g6 26.Qf2 Not horrible, but Rf1 was crushing. [ 26.Rf1 Rf8 27.Rf6 Qe7 28.Raf1 Ra7 29.Nxe6] 26...Kf8 There is the pinned pawn. Hard not to take it, but Fritz says that Rf1 is by far the best move. 27.Nxe6+ Ke7 28.Nc5 Bb6 29.Qf6+ Ke8 30.e6 Bxc5 31.dxc5 Qxc5 32.Qxf7+ Kd8 33.Qd7# Black checkmated 1-0
