kk gets put all-in on the river

[tripp0807]

He miniraised the flop - this screams top pair on this flop, unless you've got a read on him that he'll limp-call with a pair of threes or maybe eights in the hole UTG. He's probably raising preflop with tens.

You let him get away with it and showed weakness by just calling. RERAISE HIM AND SHOW SOME STRENGTH.

He's showing further weakness by checking the turn. If he's trying for a second check-raise then he's either a) an idiot or b) thinking you're an idiot. It's more likely that he's an idiot. Put him to the test by shoving.

All in all, with the action preceding the river, your call is correct. You cannot fold this.
