bogus HU MTT structure

this has probably been talked about already- but I couldn't find it with any search.

What's the deal with HU MTTs online?

I've only played them on Stars and AP, and I was amazed by the way both sites handled "byes."

Here's how it works: if the amount of entrants is not a 2^x number (2,4,8,16,32,64 etc), then the "remainder" players "play-in" to the tournament. or another way to look at it - some players have byes.

fine- that works.

here's the problem. 1st round everyone starts with 1500. the winners get 3000 and go on to round 2...the byes (who got a free pass past round 1) also start with 3000 in round 2. obviously, they should start with 1500 also in order to make the tourney "fair." round 2 should sometimes be a guy with 3000 (winner) vs a guy with 1500 (bye).

it baffles me that they do it the way they do. I'm not going to go into any math on this because i think it's pretty obvious why their way is so inferior. any thoughs?

Um - no.

A HU match is, by definition, an equal match between two people until one person has all the chips. HU tourneys cannot start with one person having a chip advantage.

A HU tourney is just a collection of HU matches. Like a shootout.

In theory the matches could have the exact same chip counts for each level - say 1500 chips to start each match. The starting stacks do not need to increase, and they definitely should not be uneven between players to start.

A Freezout implies that everybody starts with the same amount of chips and eventually one person has them all.

this is fine when everyone has to win the same number of matches to win...but how can you justify making someone "play-in" under this system? he will have exactly 1/2 the starting EV as the players who recieve byes (assuming all else equal).

when everyone starts with 1500 (in whatever round they start) and play HU matches in a bracketted format, accumulating opponents' chips as they go until there is one winner, byes and play-ins have the same starting EV. (assuming all else is equal).

for what possible reason is the "start each match with same sized stack" rule important when there are byes involved? i don't get your point.

Guy wins first match, has 3k chips. Bye starts match with this player with 1.5k chips. How is this equally EV for the bye? He didn't determine the table/round draw.

That said, double-elimination HU matches sound like fun.

how is it unequal EV?

it is equal because the bye has a 100% chance of making it to the 2nd round with 1500chips...and a 33% of of making it to the 3rd round with 4500 chips. the playin has a 50% chance of making it to the 2nd round with 3000 chips (not so coincidentally, 3000*.50 = 1500...) and then a 67% from there of making it to the 3rd round with 4500 chips. .50*.67 = a 33% of making it to round 3 with 4500- same as for the bye.

How much of a factor do you think the fact that the blinds aren't static from round to round come into play?

Bye guy could be starting as low as 10-15BB in round 2, while the play-in would have 20-30BB. Assuming equal skill levels in a vacuum, can you automatically assume that their probabilities of making it to round 3 are still 2:1?

another reasonable way to do this, which would work with your "every match has to start with equal stacks" rule, would be to treat the "playins" as satellites, where each player pays 1/2 price, and winner gets into the tournament. That makes sense. Having the playins pay the same buyin price as the byes, and start with half the chips is ridiculous.
