In general a program might exhibit more "human" play if it deliberately tried to set up positions like this. Instead of immediately going for a slight advantage, it could try to set up a deep but completely winning combination. It would lose to a computer on such a setting, but it would make for a very interesting opponent just because we expect computers to grab every minute advantage. Computers don't normally make moves with lesser immediacy in order to set up bigger attacks. It would be quite a shock to the human opponent, who would assume that the position is stable, then all of a sudden it explodes in one move. :) Eventually computers will be able to slowly crush everyone, so their ability to play in an interesting manner and produce "immortal" games in a flashier human style will begin to distinguish different programs. Speaking of immortal games, 18. Bd6 again looks like is really isn't best. The game from the position given went 18. Bd6 Bxg1 19. e5 Qxa1+ 20. Ke2 Na6. Working backwards, 20...Na6? is a mistake, falling into a forced mate in 3. 20...Ba6 is rather amazing since it refutes the Nxg7 mating attack by virtue of opening both c8 and b7 for the king to run to. Bb7 isn't enough to do this, but that's not easy to calculate unless of course you're a machine. This is a great example of how machine calculation spoils a lot of good fun. Playing Ba6 earlier at move 19 is also good. However 18...Qxa1+ appears to totally refute everything: 18...Qxa1+ 19. Ke2 Qb2! and black is way ahead. Unless someone can find a winning continuation for white, 18. Nc7+ really does look better. It just doesn't lead to an immortal game, but then an immortal game inevitably requires a more cooperative opponent. ;)
