it's impossible to concentrate for 10 hours,,,,unless your a robot,lol,,,this is where everyone makes their mistake,,,you don't Need to concentrate all the time,,,you can and should do other things while playing,that way,you stay fresh,,,,i take breaks when playing all the time,just walk away from the game for 10 mins,,,,so what u miss a few hands!! The break will make you feel way better,,,,and you can take that run to the Final Table. :deal:
