This deal, from a friendly social game, reminded me of similar ones that I have written about earlier, on the topic of unusual opening leads. For a long time now I have advocated adding into one's repertoire the opening lead of an ace against No Trump contracts to show specifically AQx as well as the more normal holdings of AKx or AKxx though with AKxx(x) and no outside entry the fourth highest is generally better. This deal was, unfortunately, not played at X-Clubs, so I have no indication that anyone else would have found the killing lead of the ace of hearts. Look at the full deal and see what would, and what could, happen in a fairly mundane 3NT by EW.
