I don't know how to deal with the donk turn

[JrJordan]

I'm a big believer that the raise turn for free showdown move is overrated. If you just call the turn bet, how often does he follow up on the river? In the current aggro 6-max games I'd guess around 90% of the time. If he's bluffing, your call gives us the chance to make another BB, where raising the turn will cause him to fold. A missed draw on the river will likeky fire a desperation bet to take the pot after betting the flop as well.

Against a more small stakes, passive table I can see raising for the free showdown to be good since there's a less likely chance they'll bet any river card. Against the standard aggro lineup though, calling the donk is as good, if not better the majority of the time.
