Players with special needs
I have had as many as three fixed seatings at once, using WER; it's not automatic like DCIR … but it's not bad, and it's never crashed my pairings (as DCIR had been known to do).
First, find a table number that will give this player the space they need - table 1 often works.
Next, do your pairings, like always. Note which two players are at table 1, and who is paired against your fixed seating player.
Change the pairings - Unmatch the table where the fixed seating should go; Unmatch the table where the fixed seating player is. Repair the match for the lower-numbered table (usually the fixed seating, going at table 1); then repair the other match, which will automatically end up at the open table.
Finally, print pairings and result slips, as usual.
Hope this helps! – Scott Marshall, L5, Denver
