Hero fold or too passive? As you see, villain is an 8/7/3 tight, profitable reg in this zoom pool. 22, 77, and even KK with some low frequency are all in his range. Villain never stacks off light and definitely wouldn't vs me here. Other than 22/77/KK, what could he possibly be 3betting this flop with on such a dry, uncoordinated board?
