two pair

[PAUL-IN]

SNG, 4 left, 3 in money, blinds 50-100. i have 1800, SB has 4500.he is very trappy!

26 offsuit in BB. field folds, SB calls, i check.
flop is 2 8 6 rainbow.

he checks, i bet 200, he calls. turn: a somewhat ugly 4. he bets 600. what to do? he bet enough that i couldn't raise him enough without getting in bad chip shape, so i didn't know where i stood. i thought his 600 bet, no matter what he had, was excellent.
