Tactics Trainer: Optimal amount of problems

Hi there,

I was wondering which the DAILY optimal amount of problems is suitable to improve with the tactics trainer. Premium member have access to an unlimited (or to a lot) of problems, but I'm not gonna spend 5 hours at it. Maybe 2-3 a day are few, too.

How many problems do you think a chess player should do every day?

Thanks.

I've heard 15 minutes of tactics problems works wonders, but I've also heard that doing problems with a time limit is a little counterintuitive.  The reason being that the time limit sometimes rewards you more for guessing than finding the right answer.  In any case I would recommend tactics trainer , it definitely has improved my rating, but that may be of no consequence to you; your turn-based rating is much higher than mine.  :)

a real chess player should solve a minimum of ten problems a day!
