Pass/Double Inversion - A Practical Argument
Kantar's book is comprehensive. Reflecting his usual style, he attempts to define LOTS of auctions. While all the individual suggestions make sense, the level of detail (and consequent memory load) is substantial. I bought it in my youth and thought the approach of having agreements for as many auctions ...
Double For Takeout, Then More Transfers
Working out how to make best use of the extra space the opponents give you after a transfer is not always easy. My partners and I have a meta-rule that X is always takeout of the suit(s) the opponents have bid or shown. (We also play that a bid ...
The best simulation software?
Dealer is a free program that is worth looking at. It doesn't have a GUI. It uses English-like commands -- in contrast to Deal and Borel (and BGen). It can be linked to any DD engine; it includes a facility to link to GIB's engine without requiring any additional ...
Handling competition over a precision 1!C
As others have noted, passing 2S is clear once partner can't double for takeout. As to what is the best method here, I think there are some important lessons from standard bidding that can be applied. One is that a takeout double is the single most useful call we ...
Books on Meckwell Precision?
My experience of using 1H to show all positive responses to 1C within a certain point range (tried both 8-11 and 12+) is that you are vulnerable to competition. While that's not likely, bidding shape first then clarifying strength, even by a simple mechanism such as step = min [or ...
Phone App for Kaplan-Rubens Hand Evaluation
True, but KnR compensates a little for this by its suit quality calculations: AKxxx Qxx Kxx Kx is worth half a point more than AKxx Qxxx Kxx Kx (but AKx Qxxxx Kxx Kx half a point less). I think KnR undervalues long suits for NT purposes, like most evaluation methods ...
Phone App for Kaplan-Rubens Hand Evaluation
All mechanical hand evaluation methods have flaws, and these are typically magnified as the auction develops. This is not surprising as most evaluators are developed for blind evaluation, i.e. before you know anything about partner's or the opponents' hands. A lot of work has been done by different ...
Phone App for Kaplan-Rubens Hand Evaluation
Jeff Goldsmith's online calculator fails to implement the additions to the suit quality count of "swallowing" quacks in seven-card or longer suits. To replicate Kaplan's judgement, Rubens' program adds 0.7 to the suit quality count for a seven-card suit missing either the queen or jack. Larger additions ...
Phone App for Kaplan-Rubens Hand Evaluation
The original article in The Bridge World ((October 1982) says ". . . a void suit provided 3 non-losers, a singleton 2, a doubleton 1: the Goren count for distribution! (Very early, we modified the shortness count by assuming that a "normal" hand contains one doubleton. Thus we did not count the first ...
European Format?
It's probably worth noting that there's a cultural heritage element to the different formats used on different sides of the Atlantic. Round robin competitions are commonly used in many European countries in a wide range of sports. All the major European soccer/football (depending where one comes from ...
