Slospin.net

Yet another great (well, in my opinion, at least) bridge site for handy reference. There are four major categories:

• Conventions
• Treatments
• Systems
• Agreements

The Conventions part features not only the most common conventions you see on the profiles of BBO players, but also articles on carding and leads. You can get a handful of doubles, and don't miss the snapdragon, which is a very useful tool if you are not obsessive-compulsive about the penalty double at the 1 level.

The section of Treatments includes

• Balancing Seat Bids
• Cue Bidding Opponent's Suit
• Cue Bidding for Slam
• Fit-Showing Bids
• Leads
• Law of Total Tricks
• Losing Trick Count
• Minor Suit Bidding Principals
• Opening Bids of One-of-a-Suit
• Opening 3- and 4-Level Preempts
• Overcalling
• Point Counting
• Responses To 1NT
• Responses To 2NT
• Responses With Interference
• Reverse Bid
• Squeeze (Rule Of 14)

Systems do not offer much for the SAYCers out there so just for the record there are system notes on an approach to the "Two-Over-One" system, based mostly on Max Hardy's treatment, as well as a condensed description of "Simplified Precision" by C. C. Wei. However, remember curiosity killed the cat...

The Agreements section was a revelation for me, personally, cos I had never seen such a detailed, well-structured example of what a "partnership agreement" might stand for. You can't count on me to have much experience, so if you have seen similar stuff somewhere, please post. It is a great idea, and seems extremely useful even if it only helps one sort out differences with one's more or less regular partners.
