2 5 live game las vegas

villain 1400
hero 1400
10 handed game

villain seems very fishy. the first hand he payed he limped called 40 with q10hh, and x/r T on q76ss2 board. he is a younger asian kid. he had been limp calling a lot with a wide range.

villain limps. i make it 20 from mp with kjoff. old man calls from bb and villain calls.

flop j23ss (pot 62$

villain chk. i bet 30. villain calls.

turn 3 (pot 122$

villain chk. i bet 70. he calls quickly

i think villain range is top pair a lot of the time and flush draws. also 22-99.

river 7 (pot 262$

villain chk. i value bet 110. to my surprise he raises 375$

not sure if i should be value betting this river. i think he would bet his missed flush draws not x/r me. he could have floped sets and played it this way because of the flush draw. his line is so strong, but im not sure what he has in this spt. maybe 77 or jxss that made 2 pair. what do you guys think??
