Peshka

Who has  Peshka Courses software? I have been working on the  Defense course and have found it very helpful. Which of the other Peshka courses have you found to be good? 

I have quite a few and I like all of them.

Which one has helped you to improve the most?

It's very difficult to measure because I've always done several things at the same time. 

I think that for most people a tactics-based program like CT Art would bring about the fastest short-term improvement. Other aspects like strategy and openings are harder to correlate with quick improvement unless they improve one's tactics and calculation abilities (which they can, of course, if studied correctly). 

So yea, it's sad to admit but most of the games played in our level are decided by tactics. Therefore, greatest improvement would come from strengthening said area.
