Hero is perceived as young kid with aggressive image imo. Hand is pretty standard, but would appreciate comments on river sizing because I think its a spot where I could bet either very large or very small.

Stack sizes are $2k effective.
HJ(hero): opens to $30 with KQ
Button(villain): raises to $105
Hero: calls

Flop: Q93
Hero: checks
V: bets $100
Hero: calls

Turn: 6
Hero: checks
V: checks

River: 2
Hero??

Definitely want to be leading river b/c I think V checks too many hands back that could call a bet. Question is do we go big or small. Honestly think both have a lot of merit. Any comments are appreciated.

going bigger otr seems fine with KQ specifically but it looks a lot like what it is - you trying to extract value with a hand we didn't get enough value from thus far. what else in your range do you credibly rep here? meanwhile you have tons of hands that have bricked out.

fat value: basically 54dd and some % of whatever combos pre you're calling oop with of 99/33/Q9s(?) that didn't x/r flop for some reason.

thin value: kq, qj. maybe JJ-TT? save QT so you have some TP in your river check range.

when considering how we'd play most of our range, i like a bet 50%-75% of pot here and mixing in bluffs with any floats you have that don't block diamonds or JT.

all this said i think smaller-size x/r flop can be sexy when you have aggro image depending on V. something like $270-290ish?

I like a bigger bet on the river to look bluffy, but I doubt you are getting called often regardless (unless you are actually behind, of course).

Considering your entire range, probably not going to have a ton of bluffs but you will have lots of value on this river. The best bluffs would probably include hands like AJ without a diamond, and any ax clubs.

KQ is definitely going to be in your value range.

With that being said I like a 50ish% bet size. In regards to your entire range you would need about 1 bluff for every 3 value bets and that seems about right.

Fold pre against the 3bet. I don't mind calling this 3bet with hands like QJs but the worst offsuit hand I'll be calling with here is AQo.

As played, flop and turn looks good. I'll bet around $250 on the river for thin value against TT/JJ/AK/86s/weak pairs. I'm folding to a river raise, since we have the Kd in our hand.

he can call with lower pairs, and he can think you are bluffing or miss a fd.
