So I have been playing 2/5 live for 3 years now. Occasionally I have to play 1/2 waiting for 2/5.
I think I would rather be forced to watch Breakfast at Tiffany's while eating spam on vegemite coated with Ex-Lax .... ok maybe not that bad.
Bluffing is incredibly difficult so you are forced to mostly play for value. It is so slooooooooooow as everyone wants to limp in. Every pot is 3, 4, 5 way with people making agonizing decisions with 3rd pair shitty kicker on a 3 diamond board trying to figure out whether player A who just shoved $120 is bluffing or not with an unimproved AK. The rake and short stacks murder your winrate while the clueless woman screams I knew that card was coming I could feel it as she runner runners your flopped nuts for a tie pot.
EVEN with all that I still make money but man it's painful.
To me there is a special definition to Bart's race to 2/5 comment about 1/2.
