First hand is an easy river fold.
Second hand, raise more everywhere. I probably pay off on the river, but its close.
Third hand - WTF?!?! You're turn action is [censored] awful. What worse hand is paying you off here? Check behind and maybe call a reasonable riverbet.

Take notes on what people are checkminiraising you with, different people do this with different hands.

Hand 1 I'd bet flop, call his turn raise and fold river.

Hand 2 I'd bet a little more on turn hoping to get called by KQ,KJ,KT, which HU will not fold, then call river with 3-1

Hand 3 I'd bet a litt more on flop, but that probably doesn't make a different. Once he calls your minireraise on turn your hand is no good so fold river

Hand 1: We have position, so I cbet. Turn looks fine, but I bet a little more. Easy river fold.

Hand 2: Raise to at least 4bb pf and pot the flop. The river bet isn't big, so I definitely call.

Hand 3: Bet more on the flop. I pretty much shut down if called. We don't beat much...I guess if we hit top pair on turn we c/c, but your b/3b is spew. River is easy fold.
