.25/.50 Cash HU

I won 3 buyins in less than 70 hands, now I realize that probably equates to about 300+ plus hands in full ring game but still 30 min time aint bad. Anybody really concentrating on these, if so I would appreciate your feedback to this question. I see all the time people sitting with 2.5 to 4x buyins waiting for someone to play, is this truly smart? Anytime I get more than 2x buyin I will cash out because I don't want someone try to double and then leave. Comments please.

Well here are the three big hands from my above session.

I had be mixing up my raises, so when I opened and was re-raised I felt my call was ok. I felt this flop was ok for me and that I was more than likely ahead, however I decided to peel because I felt like he had set me up for the check raise. Turn was my gin card and after he check I fired a 1/3 pot bet and was pleased when he called. River was a safe card for me, I wanted hem to pay me off if he had a big pair and was pleasantly surprised when paid me off.

This was the final hand and it happened about 3 hands later, I was just trying to take a similar line as the previous hand, the only difference was the pot sized shoved at the end, I don't know if I like this bluff now that I look at it, but it worked. Comments Please on this hand?
