Here is another way to beat material hungry players. It looks like queen's gambit in the begining but it changes from the fifth move and takes the form of a trap.

White can capture black knight, rook or queen with Nxc7+ and when Black get rid of the check capture the unprotected Queen with its own queen. White will win this game easily.

Here is another trap this does not end in checkmate  but gives a lot of material advantage.

If you find yourself in the trap play Nc4 instead of saving the bishop and after white captures the bishop with the pawn you can deliver a smothered checkmate with Nd6
