Italian Game: Rousseau Gambit

Just how rated is white?
Anonymous players, not sure about their ratings. But according to study statistics, even many 2k+ players fall for this (or other tricky lines) of Roussea gambit.
Study says there is only one proper response.. looks very similar to Vienna gambit.
I kind of liked this trap. White should play Nc3 instead d3 to threaten the pawn. And instead Qe2, white can play Nd4. It might seem a blunder, but actually after black captures the knight, white have Qh5 and black position is messed up.

Yes, 4 d4 is a Vienna Gambit (1 e4 e5 2 Nc3 Nf6 3 f4 d5) with colors reversed and an extra move 3 Bc4 for white.

I kind of liked this trap.
Not just a trap, it's a whole gambit. There are many other lines in Rousseau. Most of them are tricky though. One should know how to respond them at least.
This one i shared is the most damaging line, others usually give positional advantages & initiative and attacking chances.
Not very expected in Italian as black

It also shows some resemblance with the Queen's Gambit Accepted.
Sacrificed pawn can be taken back after a simple d5. It kicks white bishop and gains a tempo to capture the pawn on f5 with newly opened light bishop's diagonal.
trying my new study on unsuspecting victims, this one chose the funniest line so deserved to be published here
I love observing their reactions on some awkward but still very accurate lines.
Must be like "ohh.. this was always here? for ages?.. and i never noticed?! wth :#"
It's priceless
