Dont fold pocket 8's preflop regardless. Nice bet out, go for the check raise on the turn, you set that up perfectly. If a club hits the river, you probly loose your action.

On second hand, I like it. When he reraises the flop, you should probly just push, you dont really wanna see anymore paint hit. just calling there isnt bad tho, if you wanna get it in on the turn. His play looks like AK or AA, or even a bigger set that you'll pay off here. Nice job, bad beat.
