important "tabyia" of the Benoni. By exchanging on f3 and developing his
knight to d7, black has secured control of several dark squares in the centre 
(the most important beeing e5 and d4) and has avoided for the moment the
dangerous break e4-e5. On the other hand, white defended very well his central
pawns and can decide later on which side he should start concrete actions.} 14.

By retreating the bishop from f3, White pursues several aims. First of all, he
intends to give his pawn structure the maximum of flexibility in view of a
further f3. From the f1-a6 diagonal, the bishop will keep Black's typical
queen side counterplay under strict observation. Last but not least, the
bishop will safely cover the back rank from f1. However, this plan has a
significant drawback. By removing the pressure from the d1-h5 diagonal, White
allows Black to expand on the king side unhindered.} (16. h3 {was examined in
