A couple of meh MP limpers, button opens to $300, hero 3bets to 1K in SB with AKQThhxy, folds to button, he calls. Heads up flop, T53r1h. Hero?
10K effective to start the hand, assume both players are competent aggros.

Option A) Cbet flop. If called, barrel all broadway turns, check call heart turns and Tx.
Option B) Check call flop. Same turn plans as above.

What actually happened: hero cbets 1K, button raises to 5K. Hero?

I think flop cbet might have been a mistake. Would appreciate thoughts on any element of the hand. Thanks!
