Playing this cashgame buyin I prefer to fold, generally the players had more ability that the players from smaller buyins, In his hand I can put him in a range of cards that can play well the post flop like 88+, 89, 8T, 9T, 9J, JT.
There are no much hand that will donkbet here, I think that he will bet only value hands trying to avoid be beat for better hands, he can have two pairs or a set with afraid to be beat for a straight or a flush, maybe he can have a straight.
I don't think he will bet his draws, but it will depend about the reads and image table of he, the other player and your. Some players will bet JJ, QQ, KK and AA, but in general these players will 3bet or 4bet the preflop.
