Middle game Strategy

Pin It

Black to play
Rowson, Nonathan --- Emms, Hohn  2008

Imbalances
1. Black King is safe.
2. White king has not yet been castled.

3. Black's e4 pawn is not sufficiently defended.
4. White's d4 pawn is undefended.
5. f4-square is weak and White may try to exploit it.
5. The game is in the transit mode of middle game.
5. Black will try to defend its e4 pawn or advance it to e3.

What should be the Black's strategy?

White's 11th  move was Bg2

(!)  11 ...Re8 Nf1 and now either Nf8 ( or to my mind more enticingly 12 ...c5!? since White has not time for the Positionally desirable 134 dxc5 Nxc5 14 Bg5 Nd3)

(2) 16 b3 Ne4  17 Bd2 avoiding simplification with chances to develop a serious initiative.

(3) 18  Bxf6  gxf6  19  b3  c6  20 Rxf6  Be6  21 Rf2  Re3  22 Rf3 ( Jonathan determinedly chases Black's most active piece in a bid to liquidate to pure structural advantage.
