I either bet/fold or check call the river. If villian has T9XX then he probably would have flopped the straight or a big draw because raised preflop and hands like qjt9 or jt97. In which case he would always bet the flop. I could see villian making this move with nutflush because your turn bet may look like a pot steal or non-nut flush trying to find out if your hand is good.
