High Chicago is a seven-card stud game in which the player with the highest spade in the hole splits the pot with the player who has the best hand. If the Ace of spades is exposed, then a King would be the highest possible spade in the hole, and so on. Like high/low, High Chicago is a declare game, except players declare that they have either the best hand or the highest spade-or both.
As in high/low, each player declares "hand" or "spade" using chips or declares in sequence. If you use chips, one chip indicates you are going for the best hand, no chip for high spade, two chips for pig - both high hand and high spade. If you declare that you have the high spade, you must actually have a spade in the hole; if everyone before you has declared "hand", you can't declare "spade" to win half the pot. You must show a spade if you declare "spade", and that includes anyone who goes pig. No spade, no split. Got the message?
If you're feeling rakish, you can also play Low Chicago: Low spade - the deuce, since the Ace is only low in an all-low game - splits the pot with the best hand. Or you can play all-low - the low hand splits with the low spade. In this case, the Ace once again takes its rightful place as the low card.
