No history with villain, only 8 hands.

I've been playing a mixed strategy from the small blind, its not ectremely well thought out but I have a rough idea of which hands to put into my limping range, which ones to defend vs a raise etc and this hand for sure falls into the limp defend.

OTF I dont see any merit in c/r, we dont rep much and likely get called a tonne IP to see how we react on the turn.

I did plan on c/r turn on a decent amount of cards though, any sort of low to middling card / diamond for example.

Once villain checks back I assume he is giving up now but we cant dismiss him checking back Kx and Jx.

The river we now need to bluff being the only way to win this pot, what size makes sense here? We have lots of both Kx and Jx? I actually think I went too big here, 1/3 pot would be fine but that could open us up to being re bluffed? WUG think
