JoannSituational. I'll bid against others I know if I can tell that their bids are bookmark bids and not really serious attempts.
If it's a serious attempt I'll often back off unless either 1) it's something that is really hard to find and I've been looking for (this hasn't really happened yet) or 2) they have outbid me on cards in the past that I was clearly making a strong run at. That's not trying to be vindictive - it's more a recognition that with some people the philosophy is there and with some it isn't.
