There are only three things you can do with your money. Flat bet it, increase it, and decrease it. There are only just so many ways you can combine them before you exhaust all possible combinations.
And same can be said of bet selection; all boils down to only B or P, no? Again, how long before we "exhaust all possible combinations"?
So we separate our play....we separate OURSELVES....how? What makes us different? Bank or Player, Increase or Decrease, Bet or No-bet....all options, all the time, and all similar. I face these questions just as much as the next guy.
What makes you, or I, or anyone any better than the guy sitting right next to you at the table? Probably, in the end, not much at all.
So the difference is, after all is said and done, probably rather minute. But, my friends, it is in that minutia.....
