  Play a small .

Partner's 8 lead is a high spot card, either top-of-nothing, or a singleton or doubleton.
He definitely does not have an honor, which means that South holds A Q J.

In other words, your K is dead in the water.
BUT, if you play it to this trick you hand South three tricks, while if you play a low he can only get 2 winners in the suit.

The extra winner would permit South to discard 2 of dummy's losers, and this would give South the contract.
