(FR) QJs - monster draw in blind war

Pre you can mix up with 3bets, but QJs is good for both.
Raising flop IP looks fine to me. I always like to play the draws agressively but knowing what to do on future streets in case I hit and in case I don't hit. What did you had in mind?
You have a great hand to triple barrel bluff, blocking value combos of villains range.
I think sizes are ok. Another option would be min-raise flop, bet between 1/2 and 2/3 OTT and then overbet shove the river. The way you played it, it's going to be a PSB OTR.

I think you have to call the turn shove.
You have (100-3-12-19,2) = 65,8bb left.
SB has (134,2-3-12) = 119,2bb left.
His raise is to 85bb (what you have left before your turn bet) because he has you covered, so the pot would become 30+85*2 = 134.2bb

So you have to call 65.8 to win 134.2bb which 2:1 or 33% equity.
I think you have about that here with your monster draw.
I did some calculations on Equilab with and came up with this:

Board: Td9d2s6h
Equity Win Draw
SB 60.07% 60.07% 0.00% { 99+, 66, 22, AKs, ATs-A2s, KTs, QTs, JTs, T9s, ATo-A9o, J9o+, T9o }
BB 39.93% 39.93% 0.00% { QdJd }

I considered we could overplay overpairs and even have 66 (which I don't know because of the flop action), ATo and A9o with the diamond ace.

I would just 3bet PF
As played : I just call OTF - You have a monster draw and You can take advantage that You have position on him. I would raise when I would be OOP.
OTT bet/fold is very bad - If You dont want to bet/call OTT just check back - 6h is not a scary card for him

Villain had

I would have called the flop. Like played: He called a 2 bet on the flop(strength) and checked to you on a turn, which brought an unimportant card. You should have checked here for getting a freecard.
I think that Villain knows about your high- aggressive level.
You are ip and would let him play against your whole range if you just would‘ve called the flop.
If you were oop your line(check- raise) would be more decent (protecting your checking- range)
