LEAD WITH THE ACES
ANSWER: Sometimes a cigar is only a cigar, and a bid in the fourth suit is occasionally natural, not artificial. Here, a call of two clubs shows clubs and is limited by the failure to jump to three clubs (which you would do if the spade four were the king). You would certainly guess that clubs would play better than no-trump here, and since you can offer the suit to play, that seems a sensible option.
