I never play blitz and rarely play quick games. Chess is a game of strategy, wittling down an opponent's defenses and formulating strategies while demolitioning your opponent on a single blunder. Blitz undermines this strategy completely, as it is based on pattern recognition, memorizing openings and opening traps, and making sub-par moves in the interest of preserving time. Quick is okay, if it is longer limits, (10+ minutes or 10 minutes and increments) but I still prefer OTB tournaments and turn-based chess.
I have noticed, however, that quick games hurt my OTB games, because I work on time rather than strategy. So in that way, I have had similar experiences.
I joined this site with the goal of improving my over the board chess game. At first, I only played turn based chess and my game got better really fast. I quickly moved up to a 1500 rating and my over the board game improved as well. I felt pretty good.
I started to play live chess and I found that I could only play quick games because I always disconnected on longer games. I played 652 quick games and got to be pretty good at it. I had 238 losses and a huge number of them came from disconnecting. Sometimes I would disconnect two and three games in a row, on bad days.
I found that my turn based chess rating plumeted to 1326 and I had 20 or so losses in a row.
I am back to only playing over the board and turn based chess. My rating has went back up to 1360 and I feel like I am back on track.
Anyone else have similar experiences with quick chess and blitz chess, as far as hurting their chess game?
