10nl TPTK Not as standard as I thought

Villain is 19/9 over ~100 hands. Hasn't done anything particularly memorable.

Edit: Maybe this should be in beginner's circle, not FR. My bad.

What I'm asking is, what do you do here on this flop?

Don't immediately dismiss it as stupid or whatever, because I've asked a bunch of people and I'm getting all kinds of different responses. Some favor a flatcall, some prefer a raise. Some want to just try to get it all in right here. It's turning out to be more worth dissection than I initially thought, maybe some players as bad as me will get something from it. So please, all you super experienced players, give some of them a chance to consider it before you throw in a one line response and essentially insult me for asking.

Following action and results in white.
Hero calls $0.4

Turn: 5s ($1.7, 2 players)
SB checks, Hero bets $1.2, SB goes all-in $5.85, Hero calls $4.65

River: Kh ($13.4, 2 players)

Final Pot: $13.40
SB shows: Ks Kc
Hero shows: Qh Ad

SB wins $12.75 ( won $6.1 )
Hero wins $9.4368957093138E-16 ( lost -$6.65 )

Raise for sure: $1.70-$2.00. Call a shove, or shove turn.

you have tptk with a draw to the nut flush. It is time to start building the pot. I would raise to about $2.00 here and work at getting the rest of SB's chips in on the turn.

^^What these guys said.

You are behind a pretty small portion of his range, and even if you ARE behind, you have a huge redraw.
