Another great resource is the "Chess Tactics Server" (http://chess.emrald.net/). Every day I visit this website and try to solve some puzzles each day to keep my mind sharp and practice studying positions looking for the winning ideas.
Over years of constantly studying chess tactical puzzles I feel that it has really helped to improve my chess play.
I am kuldeep Bharadwaj from India & playing the chess from 19 years. Still I am 35 years old. From some years (may be 4 to 5) I am facing some chess problems like correct calculation and long analysis the position. Basically I want to ask to all the senior member's of Chess.com that How can I get again my fast chess calculating power. Is there any age factor. Still I have 1976 Fide ELO rating. Is there any way to achieve the 2350 Fide rating. I have played many games against Machine & humans before 2002 that time I could calculate 10 to 12 moves series in many ways. People called me the master of city. But now I have nothing in my mind. I have lost my calculating power. Now a days I play only move to move. What should I do. I have left physically sports cricket, exercises etc. May be this is the cause. I don't know Please help me.
