I bid my AKQxxx twice with the intention to compete, so I suspect my opponents might be short, but it turned out that the shortness was in my partner, so -1 became +2.
Another hand I held AKQxx, and the shortness was in one of the opponents. The contract was cold.
Should I always stick to the textbook and lead from AKQ-long against suit contract under any circumstances, even if I suspect there may be a shortness? Is it always the best lead?
