First hand is 25/25 but let's say it's first hand at 25/50 and you have no read.

With 200XBB hero should be very concerned about making the 2nd best hand. I'd try and keep the pot small.

PF raise of 500-600. I'd also consider not raising at all and playing it strong ATF (probably my preference here).

If I raised PF then ATF I'd probably check behind. The flop is very coordinated for a speculative hand. The flop clearly didn't hit hero, and villain should expect to be able to move hero off many hands with a c/r. Many drawing hands want to assert there FE at the flop.

It looks a little w/t. Hero is giving equity to avoid going broke in the hand with so many chips behind. Unless a big card comes off villain will want to get payed if he flopped big and lay in the weeds - usually.
