KtxP
White’s sixth move is bad, and you immediately take advantage of it. If he takes your Knight with his Pawn, you will take his K B P with your Bishop, and say “Check.” If he takes the Bishop you win his Queen. If he moves his King you check again with your other Bishop, which will force him to take your black Bishop, and lose his Queen.

If the beginner will examine the position, he will find that there is no way of escape for the King, and Black wins.
Openings are usually divided into five principal classes: Those in which the first piece developed is the King’s Knight; those in which the King’s Bishop is the first piece brought into play; those in which a Gambit is offered on the second move, usually a sacrificed Pawn; those which are called Close openings, securing a good defensive game for the black pieces; and those which are Irregular.
