Online chess training

Hi,

I guess this question has been asked before, but I can't find it.

I want to know wich website is best for tactical training - solving problems? I like chesstempo - are there good benefits if you become a paying member of that site? What about chess.com's training things - are they better than chesstempo? Are there maybe other recommendations?

Thanks! 

For a beginner like me, Tactics Trainer has been helpful.  I am not familiar with chesstempo.

No personal knowledge of chesstempo, but another player, in another thread said the tactics trainer was geared for pattern recognition and chess tempo was more for calculation.   The important thing is to train every day whatever you choose.  Good luck.  Of course Coach Heisman would say buy a book on simple tactics, go through the puzzles dozens of times until you can recognize the pattern instantly.  I think it's all good...
