White to play
Capablanca -- Milner 
Margate 1936

Imbalances.  

Black's h6 pawn is weak pawn Which is guarded by Knight on f5,
if White plays Bxf5  gxf5 then White can easily capture h6 pawn.  White can
exploit the weak f4-square by posting its queen on f4.  White's Bishop pair is
centrally placed where as Black's knights are well advanced.  But these
knights are actually quite insecure.} 1. Ba1 {( One of the best things about a
Bishop is its ability to sit at a safe distance from the battle and still
exert strong pressure on the position)} (1. Bxe5 dxe5 2. Bxf5 gxf5 3. Qxh6 a5
4. Qh5+ Kg8 5. Qxf5 axb4 6. Rc2) 1... Rg8 (1... h5 2. Bxe5 dxe5 3. Bxf5 gxf5 4.
