Chess computer breakdown

Feller

I was just wondering if I am alone or some of you out there have experienced the same thing.  Many of the chess computers I play seem to play brilliantly until they come up against a strong disadvantage.  Chess Titans on Vista (of course not a top line engine but...) even on its hardest setting seems almost to go into Kamikaze mode when it starts loosing badly and it will needlessly sacrifice pieces etc.  I am not a programmer but I wonder why such a phenomena could exist on programs designed to coolly make rational moves regardless of the situation.  It is almost like the computers become unnerved.  Then again maybe it is just me...

I have found the same problem. That's why I try to play with humans whenever possible.

Im not sure, but my guess would be that the programmers spend less time on the AI in that situation. The thinking being that it's better to not get in a situation where you are losing.
