So I'm trying to learn some HUNL. I come from an MTT background and have not played much HU at all. Please feel free to rip into me if I played these horribly. All these hands were from sessions which didn't last long so didn't have too many stats.

Hand 1 - http://weaktight.com/6194640

When he checks the turn with the hand he shows up with here what can we take away from that info? Also is my sizing ok on the river? I didn't feel like he had much of a hand the way he played it which is why I went v small.

Hand 2 - http://weaktight.com/6194636

The turn I was very unsure whether its best to bet/call, ch/c, ch/rr  etc.....any help would be good.

Hand 3 - http://weaktight.com/6194942

Again unsure of the best play on the turn.
