The idea of this sneaky move is to setup a tactic that wins a knight if black's not careful.

Main Line - 6...Nbd7

[edit | edit source]

The best move and the refutation. Black develops the other knight and supports the other knight.

The Trap - 6...Bg7?? 7. e5!

[edit | edit source]

If black goes for the normal dragon theme, they lose a tempo with. e5! as the move 6. f4, in fact prepared e5.
