Reads: <font color="blue">No reads on SB, he's got stats of 18/14 over a couple hundred, so probably competent. UTG is a huge donk. I decided to lead here, cuz I really didn't feel like I could count on him c-betting, and any hand he c-bets with he'd probably just raise me, driving the others out and I could get it in with him. Thoughts on that and what to do here plz. I'm pretty sure pf is fine, getting 7:1 and closing the action, but feel free to disagree if you may.</font>
