The Nimzowitsch Gambit is another gambit chess opening for you to play by letting d4 drop. 4.Qg4, a move that Nimzowitsch liked in various systems, is put to work here. Black will take of course with 4...cxd4 and after 5.Nf3 Nc6, Black's strong point is consolidated.
You have a lead in development and an initiative on the Kingside in return. After further moves Black may start action on the Queenside but this is okay. You should be able to get your attack going on the Kingside much faster than your undeveloped opponent can threaten your Queenside.
The kitchen gets hot quickly as in many of these opposite side castled games. It's just a question of holding your nerve and winning the race to mate. Winning tempi off enemy pieces with your storm trooper pawns is as crucial as ever in these situations.
