3betting is turning our hand into a bluff. Both calling and 3b'ing might be +EV but calling is more +EV. Wtf is a captain? Why would you want to run over the table if you'd be giving money away in the process? Calling down doesn't actually let him take us to value town. You have the option to fold anywhere in the hand.

Also please try to get out of the "top pair isn't a hand i want to stack" mindset
