I shoved here to get the BB player off the chop. I thought the Qs was a good blocker to a lot of his flushes like AQ, KQ, QJ, all of which he could cold call the 3bet with preflop. I also thought that I could discount some of villain's flushes since they should probably donk-jam this river with a flush. Is this play too aggressive or does it make sense?

EV (check back) = 109/2 * p (villain doesn't have flush)
EV (shove) = 109 * p (villain doesn't have flush) * p (villain folds without flush) + 109/2 * p (villain doesn't have flush) * p(villain calls without flush) - 105 * p (villain has flush)
