I am always super uncomfortable facing donk bets, especially on a wet board like this. I discounted any flush combos since he would probably check to me to keep my bluffs in play, and is charging the draw. Only 6 combos of pocket 5s let that beat me, and he probably 3-bets Js and Ks. So ive got to make the crying calls all the way down? Is a raise warranted at some point?
