Prep for the Worlds 08

In the Worlds 08 events, teams often invest some time in preparing for their opponents. Canada's Senior team, leading their group after day 1, had each team member look at 2 or 3 of their opponents, and determine what, if anything, required some countermeasures.

Btw the Canadian teams are blogging at:
In particular see Open Team NPC David Willis's (not the David Willis with the newspaper column) blog at:

For the Open team we looked at the 16 opposing teams, and categorized the various methods that could be encountered - it is "could" since most teams have 3 pairs, but only 2 of those will sit in any one match. One might not face the strangest systems even after getting ready for them.

For the methods the open team might encounter, a booklet on countermeasures was prepared. However this booklet might never be actually used in bidding of any of the matches. Here's why:

- Each Canadian pair has their own methods against commonly used openings
- As mentioned above, the Canadian team may not face some of the more unusual systems
- Unusual openings and follow-ups may never occur in the 16 board matches
- The Canadian pairs may decide to use natural bidding against anything mindboggling

Here's the table of contents for the booklet:
