35PTBB/100
Nice job sir. Obviously unsustainable, but very nice nonetheless.
I think you have touched on a few of the differences. 6-max games are donk magnets. The short stacks are more donkish and there are more of them. At the sites I play on there is better table selection too (Stars, FTP, Tribeca, B2B). Not only more tables, but more tables you actually want to be playing at. Just find a loose table with 2 or 3 30-60% stacks and get position on the big stack(s)s and you have yourself a game.
I think postflop you can play more hands more aggressively. For example, if you have QQ as an overpair you are less likely to run into KK/AA than at FR. Trouble hands go up in value (KJ, QT, KT, AT, etc). More people are willing to play any ace (and sometimes king), so AT, A9 will outkick your opponent more often, stuff like that
Another major difference is you can get better reads at 6-max as everyone is playingmore pots. Its very easy to spot the bad players.
Now that I play 6-max I wonder why I ever played FR. I sat down at a FR 400NL table on Stars recently and everyone at it was a TAG, full stacked, and seemed reasonably solid. Once I realized that I knew it was
at best marginal to play there. I move over to 6 max, and there might be 2 TAGs at a table and rarely are any of the loose players truly good. Good LAGs are few and far between.
Oh, and you get to play more hands/hr so your hourly winrate goes up as long as you can keep winning the same BB/100. I am finding I am exceeding my FR winrate, so I make that much more money.
