First Game Revisited

Start game two years ago at Winterthur Chess Week. The first critical situation showed up in the 12th move.



White just has moved 12.Rfe1. No check. Capture: 13.Bxf6. Threats: Q-R battery x-ray on Bishop e7, 13.d5.

Black to move. No check. No capture. Threats: 12.-h6 and 12.-Na5, to attack the Bishops. Na5 to be ruled out - move every piece once before moving a piece twice, and there is no tactic here.

First assessment: White has more forcing moves and is better developed than Black. Black must improve his position, including quiet, developing moves into his search. Worst standing piece is Bishop c8. Therefore, 12.-Bd7 is the top initial candidate of the quiet moves.

Initial candidate list:
a) h6 (threat)
b) Bd7 (quiet)

Principal variations
aa) 12.-h6 13.Bxf6 Bxf6 14.d5 exd5 15.Nd5 Qd6 16.Nxf6 Qxf6
ab) 12.-h6 13.Bh4 just parries the threat, same situation as before
ba) 12.-Bd7 13.d5 exd5 14.Bxf6 Bxf6 15.Nxd5 Qd6 16.Rad1 Rad8
bb) 12.-Bd7 13.d5 exd5 14.Nxd5 Nxd5 15.Bxd5 Bb4
All are safe so far, but Black has to be very careful, White still standing better.

Final candidates: both 12.-h6 and 12.-Bd7 are playable, but h6 is more forcing. Everything else being equal, the more forcing move is to be preferred. Sanity check positive. Play 12.-h6.
