In this picture of a chess position from a blitz game played at the Internet Chess Club, Black has just captured a pawn at b2 and has two extra pawns on the board. Moreover, he has a check with Bishop to d4 to buy some time.
However due to Black’s excessive greed and the low quality and mobility of his forces compared to White’s optimally placed pieces, Black is dead lost. The forlorn state of Black’s Queen side is partially due to the time he wasted grabbing pawns.
Sometimes pawn snatching is justified and it often takes master level chess acuity to discern when pawn grabbing can be carried out, but after White played Bg5 in the diagrammed chess position Black will have no way to prevent the eventual passed e pawn from crashing through.
