Hey! This hand was plaed on a regular table, so ranges arent as tight as they would be on a zoom table. SB is a sticky rec, playing something like 50/5 ~50 hands. I know this player type hates folding, but hmmm..
I am not sure about bet sizings too. OTF he have all the sets (he will never 3bet 99). But he can have a lot of gutshots, bd straights and bd flushes. The turn helps my range, betting bigger would be better from potsize to 1,5x pot maybe?. OTR he can have a lot of 9x (except 99), a lot of 5x (except 55),some 8x (like 86,78), a few Qx, and small pocketpairs under the 9. I have a nice blocker to JT, T9, QT,K9 and to the flush and need ~60% folds to be breakeven when bombing the river. This situation occurs often against recs in this pool, and they usually call it down with a lot of thrash pair with no kicker. Based on this, I am not sure how to construct my bluff to value ratio in these spots.

Spoiler
I bombed, he snapped and shown 78o :)
