Ahh..this has been happening for the past 3K hands so far at $10NL. I don't really know what range to put him on other than maybe a standard TT+, AK here. I just arrived at the table a few hands ago. I'm pretty sure I can't continue after the turn here. Is my bet sizing okay preflop? I felt I shoud have raised more pre so I could get more money in on the flop. What do you guys think?
Only 15 hands or so on villian who has been pretty active so far. Is shutting down on this turn okay? It looks really weak but I figured Ace's will make up a significant portion of his range.
