What are, in your opinion, the best methods to improve at tactics and calculations ?
Uhh....doing tactics problems
Use tactics trainer daily, such as warming up before games. This will definitely help...IMO
I have been using the "Tactic Trainer" which is very good...not too sure about calculations...
I think TT is great for improving calculation, but thats just my opinion. Maybe someone else can chime in with more.
