As dealer I open 1spade, West overcalls 2heart  and my partner bids 3heart. This, in our system, shows a sound raise to 3spade (allowing a direct bid of 3spade to be reserved for weaker hands where we want to make life difficult for the opponents). Well, my hand is far from minimum with its three Aces so I proceed immediately to 4spade. The bidding has been straightforward:  
 
  South        West        North        East  
  1spade     2heart     3heart      Pass
  4spade       Pass       Pass       Pass    

West leads the diamond6 and dummy is something of a disappointment:    Right Symbol
