Nxe6 Qc6 5. Bxb7 Qxb7 6. Re1 Qc6 7. Qf3 Ne5 8. Ng7+ Kd8 9. Qe4 Bf6 10.

Yes, Bh6 would have to be played next in this Rxe6 line. Computers will sometimes play the "right" move for the wrong reasons. This looks line one of those times. Not that Rxe6 is the absolute right move but probably no worse than other choices like Qd3 or Bh6. My enjoyment of the game is that there is not always a best move to make. "Best move" depends on who one is playing and on ones playing style. I recall one of the classic Kasparov-Karpov games where Kasparov said that "he knew Karpov would not play Nxb5 because it is just not his style". Karpov too was often quoted by various chess authors, when he said something like - why choose the complicated road to victory when a longer strategical path will win (that's not the quote but the meaning is contained in it).Karpov also writes often, "there are many roads leading to Rome".(you can tell I'm a fan of Karpov). Computers on the other hand seem bound by ordering best moves based on a fraction of a score (but I believe Bob Hyatt is implementing some code that will play different moves against weaker opponents in order to avoid unnecessary draws).
