A few posts back I wrote about tactical hell, and how it involves reacting to other people's moves without having developed a strategy of your own.
In general, the way to get out of tactical hell is to constantly ask yourself: What am I trying to accomplish here? But another simple way to avoid tactical hell is simply to do nothing.
You don't have to engage arguments. You don't have to constantly give your opinion. You don't have to respond right away.
If you don't have a plan for taking control of the situation, your best move is to just do nothing. It is much better not to play than to play someone else's game.
