10...Nxa1 is actually the best move for Black. After 11.Nxd5 Black has a clear advantage either by 11...c6, or the newer move 11...Qh4.
So, the title should be "what should I do if they take my rook?".
9.a3 is a weak move, White should try 9.Qe4, 9.0-0 or even 9.Bb3. Or, even better, play 6.d4! insteadf of the dubious 6.Nxf7
This is a recently completed game in which I played the Fried Liver Attack. Enjoy! One of my pet openings :)
do you get point cause this is awesome!
