I think we are spending way too much time on what is (at worst) an unusual problem. I also think it’s crossing the line to talk about a player behind his back (unless he just happens to be one of readers of this forum) and not give him a chance to respond.
For all we know there may be a reasonable explanation. For example, he could have been very ill, but tried to continue to play (figuring that he was already there, and had already paid his entry fee, …).
I have never lost a game to a player that I believed to have sandbagged. I have played some lower rated players that I believed to be very under-rated. But, since they were giving me very tough games in tournaments with insignificant prizes, I felt they were actually trying to raise their rating. Sure, I know it happens – it’s just very rare.
I know that if you look at player’s performances versus prize funds, that you’ll see some questionable results. However, I’d like to point out that there are other explanations: 1. Players are more likely to try out new openings, untested ideas, etc. in tournaments without significant prizes, 2. Some players play much better at long time controls (me, for example) and there aren’t many such tournaments except those with large prizes, 3. without a large prize at stake, its easier to let other considerations affect your play (things like how long a drive home you have, for example).
The players that sandbag need to understand that they aren’t beating the system. They are sad cheaters that are beneath our notice. Not something that we should spend a great deal of effort on. They aren’t “CRIMINAL”, they are “PATHETIC”. A person won’t make much money this way – consider the costs of travelling and entering two tournaments (the one to sandbag, the other to try to win a prize) and even a “successful” sandbagger will be losing money! If the player in question really was sandbagging, he didn’t win nearly enough money to cover his expenses (around $700 payoff at the NAO). Why would anyone compomise their principles (and suffer the humiliation of loosing while sandbagging, and only get to play against lower skilled players when not) only to LOSE money?
The right way to have handled this problem was to have contacted the directors at the North American Open before play began. They could have decided to only let him play in a higher section. My understanding is that the CCA has a set of minimum ratings for players that have had outstanding tournament performances – all they have to do is add him to the list. Also, this way the player could have had a chance to respond and defend himself.
