| What does 4 
    Notrump mean here?
 1N - 2H; Transfer to Spades
 2S - 4N;
 Simply 
    playing Jacoby Transfer alone, responder's 2H bid sets trump to 
    Spades and 4N is Blackwood ace-asking.  However, when advanced 
    partners choose to play both Jacoby and Texas Transfers, they 
    have two ways to transfer and bid 4N:
 1. 1N - 2H;
 2S - 4N;
 
 2. 1N - 4H;
 4S - 4N;
 Clearly, the 
    two methods must have different meaning.  The advanced bidders use 
    method #1 (Jacoby) as a Quantitative Notrump convention, asking partner to 
    bid Slam (6H or 6N) with top1Notrump opening values, or signoff by passing or bidding 5H with a minimum 
    1Notrump opening hand.
 So with 
    method #2 (Texas), they have firmly set trump (6+) and are 
    definitely playing their preferred form of the Blackwood ace-asking 
    sequence. Thus, if a 
    player's (opponents) convention card does not indicate Texas Transfers (4D 
    and 4H transfers),  it's generally accepted scenario #1 is 
    Blackwood ace-asking. However, if they have Texas on the card, then most 
    sophisticated players would likely assume #1 is Quantitative and #2 is 
    Blackwood ace-asking. Check out
