Two Knights Defence

5 ... Nxd5?!

edit
Immediate recapture of the pawn sometimes thought dubious, at other times theory considers it quite playable. From a positional point of view it's not considered a good move due to the creation of open lines that White can now use to aggressively attack, and for this reason it's rarely played at master level. While modern computer analysis suggests that it may be theoretically playable, few doubt that 5...Na5 is a more practical choice in an over the board game.
