Villain: was unknown when We played this hand.

K72ss seems a dry board. I think cbet is mandatory against a limper recreational player. I put him a range {Kx, 7x 2x, pocket pairs, few Ax (Asxx)}. My plan was to shot 3 barrel on most of the rivers, but Villain's stack will unpleasant OTR.

What is Your default line against an unknown player who's definitely a weaker player, and why? 

TY!
