Checkraise gone HORRIBLY wrong...Help with 20+2 trips

[gildwulf]

No reads.
Bigger raise on the flop? I should have bet like 300 here right?
No more checkraising with flush draws?
Help. Please.

Hmm, im checking the river here. If he bets i will have to turn to reads or bet size to decide if i call or not, but i probably would.

Looks like CO owned you hard. Outside of a larger raise on the flop, I'm not sure what else I'd do here. I'm trying to come up with a good excuse to fold the river, but I can't.

Check the river and it's not very close, IMO. There are two possibilities as to what he has and they both have you beat unless it's exactly Kxs.

BTW, I like betting the flop here.

i never slop play these hands. just shove it right in. when you do, many think you are bluffing at the pot, and anyone wiht a pocket pair or whatnot will push right behind you (at least at the $10's). And after you flip them over and boot them, you can call them every insult you can type, and tell them to get the F off your table. hahahahahahahah

1. You don't think you'll get called by hands worse than trips/nine kicker?

2. Betting is probably best. But to be clear here. It's not because you're afraid of slowplaying, but rather to define others' hand?

[adanthar]

I think I'll get called by worse hands and probably at least be tempted to pay off a raise by better hands and most of the possibilities in the immediate future involve a raise. If I had K3, I'd like bet/folding slightly more.

And yes, I want to bet out so I can get raised by a monkey or called by 3 people in which case when the diamond comes I'm done.
