The information explosion has led to a massive increase in

opening theory. But how often do you win a game with a

prepared line? What gives strong players the edge over their

opponents is not some blockbuster novelty, but a deep

understanding of the pawn structures to which their openings

lead - an understanding that lasts into the middlegame and

endgame, and is transferable between different openings with

similar structures. In this DVD, Sam Collins looks at the

Central Majority (white pawns on a2, d4 and e4 against black

pawns on a7, b7 and e7) which is characteristic of both the

Grunfeld and Semi-Tarrasch Defences. White's space advantage

gives him good chances to generate a middlegame initiative

and a kingside attack, while Black hopes to reach an endgame

where his outside passed pawn could be decisive. Collins

also investigates the closely related passed d-pawn

structure which arises when the e-pawns are exchanged ??

here

White has a highly dangerous passer on the d-file and

the key struggle revolves around whether this pawn is a

strength or, when attacked or solidly blockaded, a weakness.

White's chances have been repeatedly demonstrated by Kramnik

and Carlsen while Black's cause has been championed by

Svidler, Ivanchuk, Van Wely and Gymesi, with Kasparov

generating significant ideas for both colours. Video running
