Why? It was my first instinct.
I can't think of many situations that I would ever lead AQxx against 3N, especially with RHO likely to have the king. At best we set up one trick to have 3 heart tricks, and at worst we give them a trick they never had coming when partner could have gotten in and shifted to the suit effectively for 4 tricks. As mikeh said there is a big difference in AQxx and AQxxx where we are trying to set up 2 tricks to have 4 hearts + some other trick.
