I don't think that I am allowed to raise on the flop, because I would just isolate myself against better holdings. Could find some arguments for folding right away on the flop, but villains sizing is pretty smallish, so I decided to call IP.

On the river, I am not sure if I have enough equity to make the call - need around 7%. On the other hand I think that I have a lot of pair + single spade combinations when I arrive at the river. So I can credibly represent some high flushs, e.g. w/ QsQx. Also Villains didnt show much strength / interest such that there should be some foldequity.
