I don't mop a brisket. I give it a rub overnight, smoke it, then I will take it out, wrap it in extra heavy duty aluminum foil with 12 oz. of Negra Modelo or similar dark beer) and bake it in the oven for another hour and a half or so to finish it off.
As far as brisket chili recipes, just take your favorite recipe and swap out brisket for the chuck/tri-tip/venison/whatever.
