In a higher sense White indeed played the opening in a second-best style. The interesting move 3-Qe5 leads White to play Be2 although normally the B is better on c4. We have a typical reversed move order in this opening. Look at this endposition: [Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "?"] [Black "?"] [Result "*"] [PlyCount "10"] 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. Nf3 c6 5. Be2 Qc7 * If Black would have played the normal Qa5 and then 4- c6 then White would either play 5.d4 or 5.Bc4 - the two main continuations. But he plays Be2, but then Black doesnt lose much with his tempo loss 5- Qc7. Because we have now identical position with the played moves in the Fruit vs Rybka game. We could conclude that Black isnt inferior due to the not best play by White. White should now play d4. With Bc4 he would lose a clear tempo. The move Qe5 pleases me for a single reason and this is the usual method you are building opening books, at best from GM games. Here Rybka is almost playing like a strong 2100 human player who's trying to bust your whole opening prep. Of course you couldnt even think about such a move because in human vs human chess such a move is inferior - because human players know how to exploit its weaknesses. Black needs 3 moves before he can castle! So White has extreme development advantages. So even Bc4 is possible after castling. All in all I would say that if Rybka plays like this against strong and above all flexible humans then Good Night, Rybka. But against a 2700 [!] computer player <gg> everything is possible because of this inborn lack of flexibility. No pun intended... I'm a lay.
