Chess is Tactics!
The title says it all 
I do believe that 90% of chess games is decided by tactics. The training rapid match that I played yesterday vs IM Terry Toh serves as a case in point:
In Game 1 we both missed easy tactics that could have decided the game:
In Game 2 we both missed a few nice shots in the middlegame...
...but the final sequence was what made this game really entertaining!
