Hello there!

We have a ton of check/call on flop and a some of value bets.
As of bluff we don't have that many and i guessed K9dd is in the bottom of our range( ?) and it felt ok to bluff with ( iF we want to have a bluff range on this flop) another good would be 98s

on the river though question is if K9dd is the best candidate to bluff with.
When playing the hand I decided to bet to make weak Ax to fold but now that i am thinking of it what Ax would villain fold??
We block A9 - he would raise AT - Would he fold AJ or AQ ?
Also K9 blocks some of his KJ KQ hands that we would want him to call 2 streets.

Also thought that he would fold since we were so deep and in nl5 we don't really bluff that much so deep.

SO which hand ( if there is any ) would you choose to bluff river with? (98dd?)
Am I out of line completely with this 3 strs bluff??

thank you
