No real reads, as I was trying out 4-tabling. Not sure if people GET reads doing it, but I hadn't. I think my image was possibly LAG at this point just due to the way the cards came out. (I am definitely not LAG, but the table was fairly passive and I'd called several times with marginal holdings in good position, as well as playing a standard game in other spots. I also had bet at a lot of pots, and I don't remember showing anything down. I also had a fairly strong hand that MP had to fold to me to a turn bet similar to this one)

In any event, that said, any and all comments are appreciated. Up until the turn this was fairly standard, but the *vast* majority of the time, my turn bet would be more like T180.

edit: no idea why the converter claims the BB is 30. It is 60.
