Which is harder?

6 max. guys play HU or HU guys play 6 max.

??

When 6 max. guys hasn't earlier experience at HU and vice versa.

On experience it would have to be a hu player moving to 6 max because a 6max player will have some hu experience through Blind v Blind hands and other situations. HU player will have no experience with more than one other player in the pot.

agreed with herb

Herb makes good points, but another way to look at it is that HU can be a crushingly tough game if you are outclassed by much by your opponent whereas 6max you usually have at least a single fish in there to exploit and it's not too tough to tighten up. A six max player might not loosen up enough or go aggressive enough to do well at HU unless he/she either really understands the premise of the game or gets some solid advice somehow; an aggressive player who is very good at HU should still be able to transition to 6max without too much problem, I think, because their aggressive play and looseness is not a big handicap (if at all) and it shouldn't be too tough to tone down.
I don't say the above is a better argument; it's just that I have a very strong memory of being a host who specialized in 6 max down to about 4 handed but got wiped out several times by very good to excellent HU players (I just did not loosen up enough preflop and tended to overvalue the strength of opponents' hands based on how i made reads in 6max). I later transitioned to HU only where I make my living now.
I have to add that I wasn't a great 6max player, probably slightly better than average, so maybe my case isn't applicable.

so much fail, i don't think you understand how sick you have to be to be a 6max winner these days, by far and away the 6max players are better poker players than HU players, and it is not even close, the fact that someone would even claim otherwise is shameful and shows their ignorance to poker and statistics. Basically, the 6max people reign as a population, the HU guys are a different angle of it that specialize and I appreciate. I respect both as I play both, but to even mention them both together is pretty ridiculous, the 6max game is so much tougher than HU unless you are on a insanely high HU level that takes on all like hasu. If your HU friend ever wants a match I'll gladly grind him down to whatever wets his gill and break hill roll.

ps, not sure if the op is serious, as there is zero chance OP could beat any 6max 10/20 stars game with a big fish in it with the stars regs involved mover a 5k+ hand sample

sorry to post this in the HU forum where HUHU players chill out, but it's the truth, so it may as well be out so OP doesn't make uuuuuuuryone look bad over time

That's a pretty damn rude way of saying what you wanted to say. I'm neither ignorant with regards to poker, nor am I 'ignorant' with regards to statistics, though you probably know more about both subjects. What you are also good at, however, is reworking what someone says in order to attack them. I never claimed HU players are better than 6max players; what I said is that HU can crush a someone very very fast if they are poor players. I didn't say why I think that, and it may be that the same can happen at 6max equally fast, but when you sit at a HU table and are outclassed the money simply flows in one direction. In a six max game you may be a fish relative to 3 players at the table, but there is a better chance that one or two players (or more) are weak as well. If your goal is to drive people away from this thread or 2plus2 in general, keep responding in this way.
And which friend, exactly, are you referring to. I play HU for a living. I am not going to play you for rolls or anything else as I am not in a dick swinging contest here. I have respect for your abilities and insights, just not much at the moment for how you express yourself.

Not sure what you don't get. I used to be a prop playing mostly 6max 3-6 and 5-10. Now I play only HU limit for a living (though I am beginning a new transition to NL, but still pretty much suck at the game).

hmm, what you are saying is basically the same, someone who feels like looking through samples could give a better estimate. I'd assume that a fish at a table full of 5 equally skilled players to a HUHU player would lose the roll at the same pace, if you add in weaker opposition than the skill of the HUHU player then it would skew this, and yes, they probably would lose it at a slower rate.

Thank you, i appreciate you didn't call me ignorant or anything else in this answer, and you're answer also makes sense to me. I watched one of your vids recently and liked it a lot. I am pretty damn sure you know more about this subject than I do, so I'm going to assume you're right on that. Most of what I've said here comes from my memory of just getting plowed when I first tried hu by people who raised and reraised and barreled endlessly and I didn't yet understand how to deal with that; whereas in the 6max games, early on, i also got rolled a fair bit but it didn't feel like it was happening at the same speed. Making assumptions from a sample size of 1 is risky, I realize , so I'll just let this go and watch some more of your vids instead

your wins and losses should be much faster, as you are playing a higher percentage of hands...also, if the person is playing a huge winner HU, they are at a bigger disadvantage and can easily get wiped clean, with the nature of playing many more hands per hour, you would see a person lose more HU actually per hour, than if at a table of 5 equally competent players to the HU player, however I have not taken statistics in a few years, nor do I have the desire to attempt, posting in the probability forum with assumptions would get some quick answers, I would definitely think HU would be quicker, but am having a hard time giving hard facts as I don't feel like running numbers.

Yep, all that makes solid sense. No need to do the statistical analysis; I think what you said covers it as well as it needs to be covered. It's been a while since I've played 6max Limit; from what you've said, I think that won't change soon.

HU is much easier at all levels as the opponent will always be weaker and one has enormous control and the skill differences make a bigger difference when heads up, one making money like three times faster than at fuller games. But there are not enough games and there is no pick possible but play the 15-30 and higher limit games with whatever number of opponents there happens to be and if one is already not there, it's best to pick another form of poker.
