Defending against a check- raise

[davet]

I have been running into several players lately who like to use the check- raise, and not to any good benefit.

A few are legitimately raising, but I have caught more than one donk who is c/r with basically nothing at all. I would like to know what your auto- response is to these types of players.

Here are a few example hands.

Me: KK

Board: 8TQ- K- J

vs: c/r on the turn (wtf?)

My action: Called the c/r and raised the river.

Me: QQ

Board: JJ5- x-5

vs: c/r preflop, flop, turn.

My action: raise, raise, raise. Call.

Me: AKs

Board: AT3r - 7- 8

Vs: c/r on the flop.

My action: Call flop, Call turn for last of table stakes.

I would like to know what to do against these kinds of c/r's. during several instances, I look at my hand and wonder what is going on. Other times, I just know that they have absolutely nothing and wonder how to handle these people.

Anyway, would it be better to re- raise, or just call. I am implying that folding is incorrect in all of these situations.

I had very solid reads on all of these opponents, and none of them are LAG. I will say the results of all the hands below.
