In the Scotch:

1.e5 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nxc6 Qf6 6.Qd2 dxc6 7.Nc3 Bd4 8.Bd3 Ne7 (which isn't the only move here) 9.0-0 Ng6 10.Ne2!

Sam Collins annotates the move with an admiration mark and comments something about "putting the question on the bishop as soon as possible", but without giving any insight, neither any assessment on the critical position which happens after 10...Bxb2 11.Bxb2 Qxb2

( I would like to insert a diagram here, but I don't know how insert image command button works )

Which compensation gets white for the pawn? Is it enought? I think is white who has to prove anything, but seems to have good prospects on the king side. White can try to advance the e and f pawns while black tries to finish his development but this seems really trivial ideas. What more aspects do you see in this position to work with?

Thx
