I call the flop to invite a call from weaker draws, I don't raise the turn because I don't see anything worse calling and by just flatting I invite the overcall from someone that feels they are getting too good of a price to lay down a worse draw. On the river, I couldn't see what my opponent could be betting into two players that is worse than mine. There are potentially a few hands that he is putting out a blocker bet with that I beat. Folding this hand to such a bet seemed strange though.
