Hey Mikey,

Welcome to the forums.

This flop is bad for hero's hand, and I agree with you on that point. SB did 3 bet pre-flop, but he could have hands like JJ, TT, and because the pot is big and we are getting very good pot odds on this flop, we don't want to fold for just one bet when we know that SB could still be betting with a weaker hand.

The A on the turn is actually a good card for us since it reduces the chances that we are up against a Ax hand. The SB is still betting, but nobody raised him yet, so he could still be betting is Jacks or whatever. How about the caller? Well this is 0.15/0.30, so a player's call generally means that he has... well 2 cards. Ok not that bad but you get the idea.

Anyways, given that the A is a good card, and that nobody other than SB showed aggression, and SB could still be betting a weaker hand we can call down in this big pot.

On the river we have to call, even if we are likely beat. The pot is so big that we need to be pretty sure that we are beat in order to fold here. The decision to call or fold is really on the turn (2 big bets) and not on the river.
