When Villain does not 3bet preflop and donk leads SMALL on all 3 streets, what is he saying he has here? Middling two pair AT BEST. Meanwhile we still have ALL the overpairs, as well as flopped sets. Heck, we can even have some funky suited combos that make a straight.
If we bet half pot, or even full pot, we might get looked up by a lot of Villain’s range. How much of that range is calling 2x pot or more?
I contend we can make almost the ENTIRE range fold if we size up here on the river!
