€5/€5 9-handed. I cover the table with €1800. UTG+1 opens to €25, MP1 and Cutoff call, I call with 5d5c on the button, SB and villain (loose, sub-optimal, but tricky player) in BB call. Pot €150, 6 ways to the flop which comes 9h,8d,5s, giving me bottom set. Checked to me on the button and I bet €90. Villain in BB calls. Turn comes Jc, completing rainbow board. Villain checks, I bet €180. Villain calls. River comes Jd, pairing board. Villain leads for €140. I raise to €400. Villain studies board for 10 seconds and then goes all-in for €960. Hero decision?
