To clarify on Hand 1, it wasn't actually heads-up, it was just a 6-max table that had broken down to heads-up for a few hands. I'm not very good at HU myself. I'm curious if the river might actually be a raise since he bet so small and I'm beating AQ, KQ, and QJ. My flop raise seems pretty bad looking at it again. It's so small. I think it was intended to be a bit of a feeler raise. Then again, his 3bet looks pretty feelery as well.

Right after I checked Hand 2 I was like "Why the hell did I just check a straight?" but it was just such a bad river card that I was initially shell-shocked, and I couldn't envision him was calling down my more-than-pot-sized bets very lightly.
