not sure if you realise but treeeeebet is a very good ipoke reg. flops so wet he litterally never gnan fold any of his value range to you. i think id prefer to peel one and reasess turn. its hard to know what your repping apart from g9ss or bottom set. your have a sick stack to push forward and play smaller pots in such a big comp.
I'm really not a fan of bet folding river. I think its just a good solid fold here 1st level. cant seehim bluffing and we are readless. and i really doubt hes making that size with qq. but he might.
I'm deff flatting here. yiu just sat down your racking your chips. he has no reads on you but it doesnt take much to 3b you in that position to put you to a test. Lets keep our range as wide as possible just incase he is 3betting wide. If you 4bet i dont think he will ever 5b ram his bluffs with no reads and he also may be the type to 3bfold value hands for info?.
