I havn't played chess regularly for about forty years, since I was at school & fell out of practice when I started work. Finding chess.com has been a revelation & reminded me of how much I enjoy the game, especially solving the daily puzzles. It's a good way of rebuilding self-confidence if you are not a regular player.
My ambition in being on chess.com ? - to raise my game to the very best it can be. But as for all of us, that's a work in progress !
