_Running 15-, 17-, and 19-table 13-round Web movements with only two
board sets_
A comprehensive set of Web movements by Tim Hill can be found at
http://web.mit.edu/mitdlbc/www/contrib.html (scroll down a ways).
The odd-table-count movements require three board sets in principle,
but it looks like the three cases given above can be done with just
two board sets, still with no relays, by twinning boards that would
need to be relayed between the two higher sets of tables into idle
boards with the same dealer and vulnerability as follows (temporarily
labeling each of the twinned boards with the number of the board it
was twinned from):
15-table Web (= Bowman) [Hill's WEB1513]
twin 13-14 into 29-30 for use at table 15 in round 7
17-table Web [Hill's WEB1713]
twin 1-2 into 33-34 for use at table table 16 in round 1 and table 17
in round 13
twin 13-14 into 29-30 for use at table 16 in round 7
twin 15-16 into 31-32 for use at table 17 in round 7
19-table Web [Hill's WEB1913]
twin 1-2 into 33-34 for use at table 18 in round 1 and table 19 in
round 13
twin 3-4 into 35-36 for use at table 17 in round 1 and table 18 in
round 13
twin 13-14 into 29-30 for use at table 19 in round 7
twin 15-16 into 31-32 for use at table 18 in round 7
twin 17-18 into 33-34 of the other set* for use at table 17 in round 7
*may be dangerous unless the two sets are of different colors
The scheme fails for higher table counts because starting with the 21-
table movement, boards 5-6 will be needed at three diffetent tables in
round 1 but there is nothing available to twin them into (assuming 36-
board sets).
I would appreciate hearing of any error(s) in this plan, or of any
other reason(s) not to try this when there are only two board sets
available - assuming a field that won't freak out over a Web movement
in the first place.
