my image is of a competent, sometimes aggressive player.

0.5/1 NL - 7 handed

UTG
UTG+1 (120)
HJ (200)
CO
Hero (300)
SB (300)
BB

Hero is dealt J9.

everyone limps, SB raises to 4, BB calls 4, UTG calls 4, UTG+1 calls 4, HJ raises to 21, CO folds, Hero calls 21, folds, UTG+1 calls 21

i was about to raise OTB to take it down/isolate IP but saw SB reaching for chips, so i decided to let him bloat the pot and then 3bet. a couple others saw that i was about to raise and then just called so i thought my limp raise would show a lot of strength. SB is a fish with a high PFR so i wasn't worried too much with his range.

HJ who is competent and tight changed my plan. i saw him limp raise twice before and in both cases it was AK and i was pretty sure that's exactly what he had. since i had some sort of hand, knew pretty welly what he had, expected at least SB to join along and we were all pretty deep i decided to call.
UTG+1 is a tight passive player who i don't know so well and i put him on a medium PP.

Flop (76) QJ3

UTG+1 checks, HJ checks, Hero checks

Turn (76) QJ35

UTG+1 checks, HJ checks, Hero checks

River (76) QJ352

UTG+1 checks, HJ checks, Hero ??

HJ in general doesn't slow play and is also careful in mw pots.
i'm pretty confident i have the best hand, especially OTT & OTR, can i thin value bet anywhere and expect to get called from TT/99/88/77? i think the only hands i'm beat by are if UTG+1 shows up with JT or AJ.

would appreciate comments on original preflop plan, preflop as played and postflop.. thanks!

Why are you calling PF? And obviously we have to vbet somewhere. Id prob fire the turn here and it would be criminal to not vbet the river after its been checked down 3 strs.

i have a speculative hand in position, deep, one villain i'm pretty sure i know his hand exactly and i assume another one is joining in.

if we fire the turn and get called, would checking behind OTR be correct? trying to get better at these thin value spots..

I bet river for like $40-50

yea bet turn, check river unimporved is good.
