To be a good player you really need to be able to make folds like this. Opponant likely knows what you've got, he bets into you and another person. More often than not he has AA/KK here. If i was opponant and I stacked Hero here with KK/AA I would add them to my buddy list.

No maybe its not that bad to not fold but I really cant see the merits of doing anything other than fold. Your hand may be good but if you shove hes not calling with AK.

If you choose not to fold then check/calling is better because it gives him a chance to try and blow you out of the pot if you are beating him.
