Sadler’s Treatment of Queen’s Gambit Accepted

Apparently Matthew Sadler really enjoyed to play against White’s far advanced pawn on e5 in Queen’s Gambit Accepted, to the point where he would tease his opponent into advancing the e pawn… Here are three examples:

164Black is very solid here; e5 pawn is a liability as much as a strength.

165in search for imbalance Black has done all he could to lure White into playing e5 and he is unable to resist.
