A great play-off format often used at the end of 10-pin tournaments works like this. Fifth plays fourth, winner of that match plays third, winner plays second, winner plays first. The fairness of this can be seen from the fact that it gives an advantage to the teams that have achieved the best finish in the regular league play. The team that qualifies first has a 50% chance of being champions, whereas the team that finishes fifth has to win four staight matches, or about a 6% chance. Of course this format works equally well with four teams. Six is probably too long winded, three too short.

i rather like dorbel's idea too .. at present the TL godmin, zyxtcba, is leaning toward a 6 team single elimination playoff with teams finishing 1 and 2 receiving a bye in round 1

i like zyxtcba's idea too, in fact i changed my vote from a 6 team round robin to a 6 team single elimination after reconsidering the nature of a bracket tournament as a season championship series

i like dorbel's idea because, as he explains, it gives the season winner an immediate spot in the finals .. all others have to earn it .. i may just change my vote again

did you vote, Tomawaky?

remember, vote early vote often

Dorpel's system with four teams sounds nice. 

 hi sedat  congrats on a wonderful campaign  we are provisionally winners but .............  Completion Bonus: There will be a completion bonus of 3 Match Points and 2 Team Points for any team with 100% participation, i.e. no unplayed matches.(10 days remaining)  so we could still lose  so good luck i know you are very busy but if you can...  there r 10 days remaining
You tell Schigolch: just sent this to sedat
You tell Schigolch: well done everyone!!!
Schigolch says: very good stog! hi
Schigolch says: however i think the completion bonus should be redesigned
Schigolch says: i think a good completion bonus has to address the following problem:
Schigolch says: at halftime say
Schigolch says: a team who hasn't performed very well has no incentive to play along
Schigolch says: while those who are in the upper part of the standings table indeed do want to play
Schigolch says: but they may have to find their partner in the lower regions
You tell Schigolch: i agree - i think it should be a point for playing each game win or lose
Schigolch says: so a good incentive mechanism has to address this prob
