One of the wierdest finishes...

[WBuchanan]

Talking of finishes - from a recent blitz game I had against Peter Jamieson, where I was white.
Black to move.
I was happy with my position - my pieces are blocking his pawns, and I have threats of my own.

Yes, it's a good one. N x b2 is the obvious try, but I was expecting a4 next.
The closed diagonal being opened is one of those amazing hidden ideas.
I've seen a lot of examples of this sort of thing recently, because I've been studying 'Turbocharge Your Tactics' from Quality Chess (no payment received for this endorsement).
Great books, but evidently not that effective in my case

Hi Robert

Yes I don't know of a way of making "amazing hidden ideas" second nature, without losing on time missing quite good, ordinary ideas!

Your description, including the word 'turbocharge' reminded me of one of the best examples, the game Mason-Winawer:

White won by 1. Rxg5! hxg5 2 Qh7+ Nd7 3 Bxd7 Qg8 4 Rb7+!! Kxb7 5 Bc8+! winning the black queen (although black managed to resist for a while).
Such a move as Rb7+, setting up a double check, used (many decades ago perhaps) to be described as 'setting up the battery' Bc8. Presumably referring to the unusual power of the double check, which compels a king move. 
Or maybe it was because some of the top English players from the 40s and 50s, who wrote many of the British chess books in the next couple of decades, were physicists!
