Bluff the Turn on a scary board heads up

Let me recreate a move I contemplated but didn't have the balls to pull off.

$5.50 SnG
BLINDS 25/50 - 9 Handed

UTG - Limps
UTG + 1-SB folds
BB (Hero) has AQ checks

FLOP: KK7 (rainbow)

Hero Checks
UTG Bets Pot ($125)
Hero Calls (to set up Turn bluff)

TURN: X

What are you afraid of on the turn?
What's your bet to represent the K?
Do you check again and then Raise Huge?
Is this type of play good, bad, meh?

Figured nobody with a king would bet the pot on the flop, and UTG limper screams pocket pair, weak ace, suited connector.

Small blinds+Small Pot+(no read i guessing)=bad time to make a play.
Its entirely possible the guy may have limped A7 suited and is quite happy to call you down with it. Same goes for 8's or better (or underpair, i'v seen it happen plenty at this buy in level).

To rep the trips though if you really want to try this is to check-min raise his turn bet then bet the river with stregnth (seems to make people fold to my sets the most often :( ).

There are easier pots to steal (3-4 limpers and everyone checks to you in lp twice....)

I agree, small blinds, but I figured it might be an easy bluff and wouldn't be hard to get away from if things went sour. Purely hypothetical though, and I guess it's probably more of a read thing.

I used to try to make this play at these levels.

But guys are usually stubborn with their pocket pair or if they paired up on the flop they usually don't go away unless you bet real hard...which is not really worth it unless you need to make a move.

Like the only way I see making this work is raising him on the turn and betting real hard on the river, but putting chips on all 3 betting periods on a bluff is scary.
