Pattern Recognization,Positional Sense etc

My observation is when I go over master games in my chessbase reader and play a game up next I play relatively incredible moves.

But after doing some tactics training when I play I look for tactics all over the game and even hang pieces.

So what is going on here?Does tactics trainer's really teach something or they are the test of our positional sense we already have?In chesstempo I dont see any IM,GM-s up in the rating list.

According to kramnik  he go over 10k games every month(chessquote.com)

What do you think on chess intuition?How were the old master's trained when we dont had modern computer's?

The problem when doing tactics trainer and chess tempo, you solve random tactics puzzle. No time to recognize tactical pattern recognition. Better study tactics books like Winning Chess Tactics by Seirawan or Learn Tactics by Nunn. You learn different tactical motiffs in each chapter. After reading one of the books, expect improvement in your tactics.

Mandy711 but after i mean knowing all the tactical motifs, isn't after that simply practice of pattern recognition? i mean if the guy already knows the tactical motifs, then he doesn't need to learn them again.

David, The OP's rating shows he does not know tactical motifs or pattern recognition yet. Reviewing tactical motifs helps. A more difficult tactics books like Encyclopedia of Chess Combination would be more challenging to relearn tactical motifs.
