First off, the best regular poker comic strip I could find is +EV by Bobby Crosby. He does a new one every Monday, Wednesday, and Friday. Check it out...good stuff.

This collection might not be updated often as I don't see too many poker related comic strips. But these are the ones I found (and bothered to save, scan, etc). The first set is from FoxTrot when he did a week or so of poker strips. I just borrowed the three below.
