No, it is call or raise 3-bet, after having either opened with a raise or called an opening raise. You are right, "fold to 3-bet" is much simpler.

I put the qualification for having called or made the opening raise in because cold calling a 3-bet is a much different proposition to calling it after having opened the betting. Maybe the difference isn't so great for limit games and maybe I could count different stats for those games?

I read the thread in PT and they seem to be heading down the same route in counting the 3-bet%/call 3-bet%, as a % of the number of times raised. I should say I have done this for all the stats. So for example, my check-raise % is going to be quite different from PTs.
