Pawn moves are only admissible in the development stage when they either help occupy the center, or stand in connection with its occupation; that is to say a pawn move which protects its own or attacks the enemy center.

On 20... Qxf6
ReplyDeleteRhal is already winning. However, a few moves later, Rhal started making weak moves such as:
23... Qf6
The best is Qc2, attacking the pawns at a4 and c4 simultaneously.
On 28... Bf5
The simple Bxa4 wins another pawn and probably the game. According to Rhal, he is already in time trouble that is why he blundered on the next move - f6, leaving the R en prise.
