Well, one could say that tactics are used to set up a position...
I'd say your Strategy is your plan, and Tactics are the actual moves you use to execute that plan. I don't think that positional play leaves Tactics aside, but the differences from tactical play are in the objectives set:
Most of the time, a positional player will look for subtle advantages in position, rather than looking for advantages in material.
oh i forgot to ask you borgqueen about your example that show a positional in 21 moves and after that it went tactics the game.so my question is......you mean that in every grandmaster game in the beginning they go poistional moves first before going to tactics?i wait again to your response.
