Hi, I would like to ask for advice how correctly bid this game as South with SAYC and not to miss Grand Slam? N: K 9 6 A 7 4 K Q J T 7 6 5 S: A Q T K Q 9 8 5 A 8 3 A K I used this bidding sequence but I am not satisfied with it: (N started with 1C): 1C-1H 2C-4C 5C-5D 6C-PASS My 5D is not regarded as control bid (cuebid), is it? So how to investigate North's hand correctly? (I see no way how to use Blackwood or Gerber...)
