Just looking for some input on these hands the first one was more of a building the pot type thing, was I wrong to do so? Second hand I think I may have overcalled on the end, I pushed a little hard I guess to see how strong he was I figured either a straight, weak ace (or AK) or I was beat, was I wrong to get this aggressive on the river in hand 2?
