6. Ne3
White has seemingly thwarted ...d5 yet again, and is now asking the Black army how they're going to save Private Ryan on e4.

There are two options for Black: abandon e4 and make another non-developing move with /6...c6/ to finally establish an iron grip over d5, or continue the charge with /6...d5/, the Atars Gambit, accepting the loss of the d-pawn and saddling White with only the minor inconvenience of having to come and capture it.

It should be pointed out here that, in fact, the suicidal-looking 6...d5 is one of Black's last remaining attempts to revive the Latvian Gambit. If it doesn't work, the swashbuckling old opening will likely be tucked away on a shelf with a label "suitable only for unprepared opponents".
