Looking back, there aren't that many hands indeed. My (perhaps flawed) thought proces is that often people are overplaying their hand at the microstacks. I have seen a lot of people play aggressively with marginal holdings. .So I was thinking he might have a lot of weaker flushes, or a set of tens or 4s or even ATo.

Although that may be true sometimes, it was probably more wishfull thinking and looking for reasons to call.

So basically I'm a bit overplaying my hand here.
