It of course depends on your response structure. With this particular hand I would venture 3♠ hoping for extra benefit from the long ♠ to offset the Q♥ not pulling full weight. If the AQ were in the minors this would be an easy call but I can understand others only choosing 2♠ which I would probably choose as well if NV. EDIT : I find the 4♠ bidders LOL as many would say ♠KQx ♥xx♦Kxxx♣Kxxx is a clear TOX in this auction, Well more power to them. Personally I can never manage to have my cake and eat it too but I guess they figured out how to manage that as well.
