Show Detail |
This hand came up in this week's casual game. You can't argue with the opening bid, but after that the auction goes awry. It's not an easy hand to bid. Looking at all four hands it isn't obvious that the par result is 3♦ X-1. This costs NS -100 which is slightly better than conceding -110 by letting EW play in 2♠. Tempting though it is to say something, East must pass on the first round, South is unlikely to pass, and even if this does happen then surely West will say something, hopefully X. The problem with a double by East is that West will read this has a T/O double and may well be tempted to bid 4♠ , especially after the 3♦ by South. The 3♦ in this auction is technically correct, it says to partner I have a long suit and a weak hand and no support for your bid. West should double this, which should end the auction, but in the event the pass lured North into a potentially suicidal contract of 3♠. In the event this is "rescued" in to 4♦, which should have been smacked.

Bridge Conventions |
Rubinsol, sometimes called Transfer lebonsol is useful in those situations where 2NT is better used as an artificial bid. For example if you own the hand and your partner opens 1NT it is best to use a double to show this, rather than 2NT. 2NT becomes a spare bid and this is the starting point for this convention. Other instances here 2NT is used initially as a tranfer to ♣ is when your partner doubles a weak two opening. Now 2NT is used to show weak hands where as a bid at the three level becomes forcing. Rubinsol takes this a step further. Finally if you play opener reverses as forcing to game 2NT can be useful when scrablem home at the three level.
