In addition to this I would probably not C-bet a board like 983 rainbow with AK. The hand is to in between making it difficult to get a better hand to fold or a worse hand to call. I would much rather take a free card and then make a decision on the turn. AK high has showdown value on a board like this but does not want to play a big pot.
Also if the opponent is short enough to check-jam in a pot limit game, then I would definitely check back, since I do not want to face this kind of action and be blown off my equity or forced to call it off usually drawing to 6 outs at best. This is a situation, which is very common in tournaments, and you really do not want to C-bet any in between hand, when the opponent is short enough to check-jam.
