10$ | 6 max | T | postflop | K9o

This would be a no brainer 3bet shove if this was a 9 man SNG.
Anyway now is calling decent. Only problem is that you aren't so deep anymore with a marginal hand. Post-flop seems standard to make a thin value bet on the river, but I expect he hits a straight. Otherwise his raise makes not to much sense.

Seems plausible to me. Just also use same sizing when you do have Tx to balance range. River bet can also be too thin. Have to remember that BU can have all better two pairs and sets. Some Tx also. So when you bet small in river it might easily be that you dont beat more than half of his call range. Its rainbow flop so question is how many bluffs we have? You kind of need to turn some Q8 type into bluff or perhaps you call some Axs you didnt shove pre? I doubt we get bluffed often here as Tx is fairly big portion of your flop call range.

PS: Its also spot where you dont necessarily want to have flop raising range versus reg. Simply because BU has so big range advantage.
