Returning to the scene of the crime

Yesterday felt like I was returning to the scene up the crime. The apprehensiveness was way up there. I thought to myself, I just need to open some tables and start playing and I will be back in game mode. Then early on this hand happened.

I sucked out on somebody. I even saw a "luckbox" in the chatbox from some guy at the table. After that, blood pressure back to normal. Maybe things were evening out. I actually hit sets 22% last night as opposed to the other way around over 743 hands. While I felt a lot better, I got my 200 points and got out of Dodge. I will take the small win (30.17 bb/100 over those 700ish hands) and return again hoping for the best.

I really didn't have any hands where I won or loss over 50 bbs. My only real choice last night was how much to bet with the nuts. Let me know what you think.

Villain is a 42/3/3.1 over 156 hands.

I bet out small on river to put shortie all in and hopefully get some action from the other guy. He min raises. Can I push or do I just put in a raise? Is there really any difference?

Have a nice day!!!
