| I think there are two good ways to do it.
The regular way is single elimination. I would not try to end each match in any certain period of time though, because then it will just be a crapshoot. If a player is losing 1600 to 1400 chips, and the blinds are 100/200, he has to go all in, to try to make the other guy fold. But wait, the other guy realizes that if he folds he will only be left with 1400, so he must call. They both go all in without looking at their hole cards. Is that exciting? Maybe, but is it poker? No. Each match must end by a player being eliminated not based on some time period ending.
Just use the normal blind schedule, but speed it up a little bit. So many more hands per hour are dealt, and each player is playing a higher percentage of hands. So the blinds should go up quicker.
If you do your blinds starting at 25/50, with a T1500 stack, one hand could easily end the match. The usual starting stack is between 50 and 100 big blinds, so its like you are already in level 2 or 3 when you start, and the matches should go quickly.
If you raised it to 50/100 and then 100/200 every 12 minutes, each match should end within 30 minutes.
Then after the round of players have been knocked out, have each player bring his whole stack to the next match, where the blinds start one level above what they started at in the previous match. So that:
Blind levels each 12 minutes long.
Round 1 - T1500 -- 25/50 - 50/100 - 100/200
Round 2 - T3000 -- 50/100 - 100/200 - 150/300
Round 3 - T6000 -- 100/200 - 150/300 - 250/500
Round 4 - T12000 -- 150/300 - 250/500 - 500/1000
This structure should end the tournamnet within 2.5 hours. This way seems a like a crapshoot still though, with half of the players playing only getting to play poker for about 20 minutes. Thats like a turbo tourney online.
It would be much more skill oriented if you had slower blind structures formatted for approx. 1 - 1.5 hour matches, like:
Blind levels each 20 minutes. (I assume you start with only 25s and no 5s)
Round 1 - T 1500 -- 25/50 - 50/100 - 75/150 - 100/200 - 150/300
Round 2 - T 3000 -- 50/100 - 75/150 - 100/200 - 150/300 - 200/400
Round 3 - T 6000 -- 75/150 - 100/200 - 150/300 - 200/400 - 300/600 - 500/1000
Round 4 - T 12000 -- 100/200 - 150/300 - 200/400 - 300/600 - 500/1000 - 1000/2000
But if you don't want a 16 man tourney to last you 6 hours, just do a round robin type of deal where every time the blind level changes, everyone half the people switch tables, and nobody plays the same player twice unless they have already played every other player.
The round robin style lets you have a heads up tourney with any number of players, and you don't have to have super fast rising blinds to keep it moving along. You can use a slower blind schedule, and the whole tournament would end quicker than if you did single elimination matches with 10 minute blinds.
This schedule with 20 minute blind levels would probably end the tourney in 2.5 - 3 hours.
25/50
50/100
75/150
100/200
150/300
200/400
300/600
500/1000
1000/2000
If you use this method, you can use whatever payout structure you normally use as a payout structure. But if you do single elimination matches, you don't really know who is 3rd or 4th, or who is 5th, 6th, 7th, etc.
A good payout for a 16 man touney is:
1st - 50%
2nd - 24%
3rd - 13%
4th - 13%
If you try to pay 5th, 6th, 7th and 8th then the top 4 prizes will be pathetic.  |
