Is this spew? ok?
how is my line untill the river?

I rarely play K10o in MP. c/f river. bet of &lt; 1/3 of pot is a bet that he wants you to call.

[TimmY222]

i just could not put on a hand after his check on the turn. a Q is a must-bet here right?
A jack with a flushdraw, combo draw or a naked flush draw i would think checks behind on the turn. then, when he bets weak on the river and i came to the conclusion i could take it away with a push.
maybe bad reasoning by me?

[wslee00]

pretty good reasoning, but i think the wrong limits to try it on. It *may* work @25NL, but villains there are pretty passive as well.

Completely unbelivable. How can the 2d have helped you, not at all.
What powerhouse hands would you check on the turn there, not many.
Can the a 21/10/3,5 villain fold there, maybe/maybe not, would he CR a naked FD on the flop maybe, maybe not

You get 3:1 on the flop and the A/9 spades might not be outs. Fold to the flop raise.

ahh..
now that you said that. The only hand i would check the turn with is Quads. or a boat trying to check raise. but that does not hold water either, couse with what big hand besides a draw do i not 3-bet the flop with.
i can maybe see myself trying to check raise the turn with AQ,KQ, but it is very unlikely.
Thanks for pointing me in the right direction.

results:
He called with KQcc.
