River decision/am I committed?

I totally disagree with this line. If I raise and he shoves, I have to fold a hand that has a ton of cards that could improve my equity here. Playing post flop is fun.

You have 640 chips and the pot is 220 to you on the flop. There's no "playing post flop" here.

Just get it in on the flop. All other options are worse.
