These positions from the recent games posted by Enrique are about
sacrificing pieces for pawns. In line with recent threads here about sacs that
either fail or succeed, see what you make of these.

Black played Ng5 and lost. The connected passed pawns on the Queenside for
compensation
were not enough this time, but given a similar position the sac may well have
been justified.

Black played a5 but here looks like a good time to play g5. Black might squirm
out of the checks and remain a piece up for two pawns.

Black avoided g5 here also and I agree with that choice.

Black plays g5 here and the game quickly ends in White's favour.
