88 in the CO.

party NL50.

5 to the flop, limped in.

flop is 6 8 K rainbow. ($4.8)

checked to hero.

Hero bets $4.

fold to BB who calls.

turn is 5, making 2 clubs.

villain leads for 1/3 pot. Hero calls?

(I was thinking either he is on draw or he is underbetting his OESD that he hit on the turn).
