The pawn structure certainly will not bother White in the endgame after 6...dxc5 7.Qxd8+ Kxd8 8.Be3 e6 9.Nc3 Nf6 10.0-0-0 Nfd7 11.f4.

Yet by avoiding the endgame Black soon lands his queen in trouble.

8...Nd7 should have been played.

White is virtually winning already.

Very nice! White won 10 moves later.

Right again! Not only because of the now half-open f-file, but also to be able to challenge White's centralized knight with ...Nf7.

With a favorable position for Black.

Stopping White's a4-a5 once and for all (though at the moment . . . b6-b5 seems a suitable response), not minding the b5 -square and the now backward b6-pawn. Black has a clear follow-up in mind though.

A fine post for the knight, from where it aims at the blocked a4-pawn and also supports the central advance of the e-pawn. After some adventures, the game ended in a draw.
