One Spade - Two Diamonds (Hearts)
Over the years, I have found that using one bid, 2, to cover long hearts with all ranges is too confusing - even in a big club setting. So I now settle with 2 = weak (8-10, 6+ hearts) or strong (game-forcing, 5+ hearts). With an invitational strength, I jump ...
The Vacant Spaces Trap
Phillip, Thanks for the clarification. This certainly makes my answers different. After the first switch, my probability of winning is at 30%. The odds of the 3rd Queen in the remaining three cards (i.e. non-Queen and not my current card) is 70% = 100%-30%. Now the host turns over ...
The Vacant Spaces Trap
Phillip, (a) I don't follow you... (b) I would not switch again. My odds is now 9/10, as opposed to 1/10 if I switch.
The Vacant Spaces Trap
If Monty Hall happened to be a co-host and offered the contestant: 1) If she wanted to switch, after the two Queens were shown, to any card in the bottom row; and 2) If she wanted to switch, after the two Kings were further shown, to the last card in ...
Bidding a perfect fit
What if North tells South that he has 4-5+ and short , and the bidding is now at the 3 level, wouldn't South get excited? Below is an auction (not mainstream of course): 1NT - 2 (transfer, 4+ hearts, GF or weak, canape possible) 2 ...
Bidding a perfect fit
Or Axx AQTx AQx xxx (better than 50%) or Axx AKQx Axx xxx (essentially a 4-or-7 hand)
ATB-missed slam
This hand demonstrates the importance of showing responder's shortness below the level of 3NT. Had responder been 1=4=2=6, 3NT would have been the best contract. It would be wrong for opener to bid unilaterally above 3NT after 3. To show shortness over 3, opener ...
Which minor do you open?
If you play short 1 (2+ clubs) and 1-level transfers, you may want to think about transfer rebids as well. For this hand,K65 x AQ82 A9654, you would open 1. Then, over responder's expected 1, showing hearts, you would bid 2 to show 5 ...
Transfers after 1NT - 2C - 2D?
Below is a scheme of giving up garbage Stayman and focusing more on game-forcing hand types.You may find it useful or me crazy. It runs as follows: 1NT-2 ( at least one 4-card major) 2-? Responder's 2 shows 5+ spades, invitational, as many now play; and ...
Assess the credit. What is the best bid?
Will be close. I would play A first, then try to ruff 2 spades in dummy. That would take care of almost all 4-3 cases, and some 5-2 cases too (e.g. E has 2 spades and 2 clubs). We are not given club spots. I could have ...
