I put his hand range as AK/AQ w/ one spade, TT, the flush, KK-JJ w/ one spade are possible too. Your 30 bet looks like your just trying to take down the pot when the flush card hits. (I think he puts 3 in pf w/ AA)

I dont dislike push here. Although call then c/f to a spade, bet out any board pair, and c/c a reasonable bet to anyhting else looks fine too.

I could be wrong.
