If you have a A8 suited and flop 2 more spades, knowing the other person has say two KK, one K picked up on the flop, now he puts you in big, I have a 39 % chance of another spade, should I keep going or chuck it in?

it depends if you are playing a tournament ( in wich stage ) or cash table and mostly on the pot , take a look at the pot odds available on the strategies the site offers it would help you decide

depends on the pot odds and stack sizes(implied odds) and the opponent tendencies
