I should mention that after 6 Neg5 h6?? Is a very bad move. GM Negi does not know how to analyze if he suggests such a bad response by Black.
Fortunately Black has two good responses. One is 6...Qe7. The second one I will keep secret until I get to play it.
Agreed, 6...exd4 isn't as bad as 6...h6 or 6...e4 are: It is even worse.
It silly to expect salvation when white has virtually not sacrifised material, he is miles ahead in development, and Black's king is stuck in the middle of the board.
