Tactics are important, as they can immediately spell the difference between life and death. You must recognize them in your games and also must be able to steer the position in such a way that tactics "should" be in your favor -- meaning to say if you exert more and more pressure on certain areas of the Board, good possibilities / tactics should be present in the position.
A famous player once said, that given winning positions to find tactics, top notch players will find them. It's getting to those positions that takes a lot of talent !!
How about easing away from tactics for awhile and concentrating on games AND getting them analysed by chess.com to go over -- going over what you and your opponent missed. That will go a long way towards improvement !
I have done 15,000+ tactics and still hover around 1200. I'm wondering what I'm doing wrong or is it that I just can't "see" the game the way better players do.....and help or advice would be appreciated.
