![]() What usually attracts me to a player whom I check out for cheating is a steady chart for several years that suddenly zooms upward. I pay a lot of attention to a possible opponent's chart on his profile page, and often click on it to enlarge it and take it back for several years. Then I can see if it is a temporary acceleration or a pattern, as most people have winning streaks. The chart (graph) is the first thing I look at when evaluating a possible opponent for one of our players. Also, I sometimes come across someone who has a very short term chart when he or she is listed as joining GameKnot several years ago. That puzzles me. If they don't play for a while, does their chart get dropped, but their original date of joining is still shown? Perhaps someone can answer that question for me. |

![]() The first game showing in my game history is October 2013 and this is also where my graph starts. There is a note saying "Due to extended period of inactivity (over a year), game history prior to 06-Oct-12 is no longer available". I guess it makes sense for them to delete games rather than storing data indefinitely for players who have left. |

![]() "Yes, we do have a specific review process that involves both automated computer analysis and manual human review. For obvious reasons, we cannot disclose specific details of what we do, so that not to make it easier for cheaters to avoid detection. We do regularly ban players for cheating. Lots of wins and no lost games is not unusual for players who only play against lower-rated opponents. Even if they make a (very occasional) mistake, they can likely recover and still draw or even win the game. Examples of concrete evidence of cheating: sudden (in a matter of weeks) and significant (400+ points) upward swing in the player's rating, after it has been established for a while; player routinely losing vs lower rated players in the past, and then becoming unbeatable vs higher rated players; significant discrepancy in player stats (e.g. tournament games vs regular games); player admitting to using a chess engine to analyse a game in progress -- "just wanted to make sure I still have a chance to win", "suspected that the opponent was cheating, so I wanted to confirm with a chess engine", etc., or "a friend" doing the same for the player. It takes a lot of time and server resources to investigate a player for cheating, so we cannot do it at a slightest suspicion. We do of course investigate all players that warrant a review. Also, in our experience, it is also highly unusual for someone to avoid detection for any significant period of time. You have to be very careful and analyse every single move, because even a single mistake can result in a lost game at any point. People also don't enjoy the hollow victory of using a chess engine to get a high rating for any significant period of time, so cheaters tend to quit very quickly. Or they get caught very quickly. The end result is that the fear of playing vs someone using a chess engine is way overblown. It is a slightly different story at the very top of the rating range, but for 99.9% of players, if your opponent has been playing for more than several months and their rating is under 2200-2400, it would be *very* unlikely that they are using a chess engine. It might feel sometimes that your opponent is cheating because they are winning, but you should be focusing on learning from the experience instead of taking the easy way out and blaming the loss on your opponent cheating. Not directed at anyone in particular, just a general observation, of course." |

![]() I tell my new players--First see if you can force mate. That beats all other considerations. Then check to see if you can prevent force mate. It doesn't matter if you pick off a queen and a rook if you end up losing by clever sacrifice. After that, check to see if you can acquire a high value piece. Can you fork or pin your opponent's queen or rook? Any free knights or bishops, or any ripe for a pawn exchange? Then check to see if you stand to lose any of your HVP. After that focus on development. When in doubt, push a pawn. |

![]() I would suggest it might be worthwhile for her to spell out what raises red flags for her, but I wouldn't want to tip off cheaters. |
