Queen sacrifice in The Scotch Game : Opening preparation or intuition ?!

Hello all Chess Players !

The next Game is for me really interesting. If one Day, i can ask a single question to Tamas Ruck (the Black Player in this Game), this would be : Is your sacrifice a opening preparation or a move you have found in the Game? Because, if this sacrifice is not a opening preparation...where is the part of calculation and where is the part of intuition ?!?

probably opeining prep.

I don't know...i don't know

I have post this game (ok i like this and i'm happy to post this) because today i have looking few games in the 5.Nb3 Bb6 6.Nc3 variation (i have looking the 6.a4 variation a another day). All of the study represents approximately 1-1,5 hours...i'm not a professional and that's for me very a maximum time i can study the idea of this line...just the idea (opening is not the only thing in chess). I don't know what represents the time of study chess for Tamas Ruck, but if he have analze completely all line (after 6...,Nf6 White can play 7.Bg5, 7.Qe2, 7.a4, 7.Fd3 and 7.Fe2. And now, after 7.Bg5 h6 8.Bh4 d6 White can play 9.Qe2, 9.Bd3 and the move 9.a4 has not played often...no, in one moment i think the Player use intuition and calculation. But i don't know...Chess is very a crazy game!!
