villain is Pie_Voleuse, pretty laggy but not out of line much postflop in unraised pot. (28/21/6.8) over 1500 hands. his AF is strange. 17/4/1.5. i expect him to be betting this flop with any reasonable piece, and i just called to keep the other guy in who was really bad (he had recently won a monster pot when he called 3 barells with A hi (no draw), and beat the other guys K hi. when he checked i assumed he had given up, but then he raised. his line really confused me.

it is hard to put him on a hand really, but it would be a weird spot for a bluff.

do you think a call is in order because his line makes no sense?
