sometimes we encounter rivers where we have to ask ourselves can we somehow bet for value even thin value, but also if we bet *any* amount, will we instantly fold to even a min-CR ?

i think this is a spot where just getting to showdown is pretty sweet.
imo fold pre is best option, suited is slightly different as we can hit a lot more equity on flops.

the *only* reason why i'd bet turn here is if villain thinks we are floating wide and he check/calls turns with AK/AQ type over cards so we are betting for value. other than that do you think he's ever playing hands like 88/99 underpairs this way? that's all your beating basically that *might* call the 100bux on riv
