Forking Pinning

I'm concentrating my attention on the first 3 (and longest) chapters of "1001 Winning Chess Sacrifices and Combinations", 1. Pinning, 2. Knight Forks, and 3. Double Attack.

Chapters 2 and 3 are really the same thing and I breeze through the problems at an acceptable pace. Find the un(-der-)protected piece and fork it, usually to a check or mate threat. They represent the joy of being able to 'do' Chess.

As I mentioned at the outset, chapter 1, exploiting pins, gives me more trouble than it should and represents the frustration of amateur Patzerdom. The reason for this is that a pin is rarely a tactic in and of itself, it's a semi-static position feature requiring the discovery of additional dynamic tactical motifs for it's exploitation.

Reinfeld position #47
White to move

White is a piece down, a7 and Nc6 are pinned and natural attempts to capitalise on this with obvious moves like Nxc6 are resisted by the counter-pin ... Qd7. Getting tied up trying to work the pin, I too easily overlook other features of the position. Far from the main 'field of action', Rh8 is both unprotected and immobilised. Can anyone spell 'TARGET!'??

1. d5 clearance of the a1-h8 diagonal 1. ... exd5 2. Nxc6 completing the clearance 2. ... Qd7 the counter-pin 3. Na5 attacking both the unprotected Bb7 and g7 trapping the Rook.

It really shouldn't be that difficult, but the lure of the simple and obvious tends to provoke blindness. There were other things I had intended to work on before Teamleague starts up again, but I'm seriously considering using the next month to force myself through every pinning problem I can find.
