No The line that you mentioned is too simple for chess programs. I did not mention Rxe6 Qxe6 Re1 Qd6 Bf4 f5 because at the position before f5 every chess program find that f5 is bad in a short time. There is no +3 or +4 after h5 for most programs Even Crafty can see it easily on a very slow hardwar(P850) and it is obvious that when it was used for hours on the root position it saw that f5 is bad so it did not play Rxe6 because of different reasons.
