opponent is known to be aggressive( inf) with 50 hands with 17/10. i thought that the re-raise could signal a Q or 2pair or set but also flush draws. the bet on the turn does not say much since he would bet with his entire range. at the river, i thought that his range would consist of mostly busted draws with an occasional Q
