QQ Deep in FT's 750k

[SwingVelvet]

Opponent is loose. I obviously considered pushing preflop, but I decided I was giving up equity since raising a smaller amount would absolutely get weaker hands to call.

Is this faulty thinking?

Then the flop comes with an Ace, and I'm in a terrible spot OOP.

Where did I screw up, and how do I proceed now?
