      If you mean how many hands you should play to have reliable stats i think 10 000+. And this might be not enough.

      if you're talking about using a HUD it really depends on the stat. since some will require as little as 100 hands and other as much as 1000 hands.

      if you're talking about analizing your game, put in at the bare minimum of 50k hands.

      100-150k hands would minimize your daily up/down swings, you will see your skill there.. (some of better players says its after 300-400k)

      Well it really depends on which stat. VPIP can give you an idea of the opponent after a 100 hands or so, but in fullring if you got a 100 hands on your opponent he was only in bb 10 times or so. So the stats like fold to sb steal and attempt to steal doesnt really tell you much since you only have effective stats of 10 hands. You probably need like 1k hands at least to make an accurate play according to stats.

      Then there's post flop stats that you need even more hands for, especially for turn and river since most hands dont even go that far. If you're playing a tag player that saw the flop like 6 times and turn like 3 times in 100 hands you really cannot play according to stats against him. Probably like 5-10k hands are needed for post flop stats.

      Not to mention that players, especially at the lower limits are getting better every month if they put at least some effort in it so 3 months old stats dont really tell you all that much about him. And in case you move up a limit you're old stats wont help much anyway since there are different players on different limits.

      Stats will get usefull against regulars when you reach the limit you wanna play on and can easily accumulate like 10k hands on them.
