During my online match with Lee Younggu, I clicked here and there and the homepage opened up, and my Go game popped up and I looked at the (AI) reference without thinking.
This reminds me of something I have observed more than once or twice in amateur go. A strong player walks by a game featuring his friend, smirks and makes a remark, probably unthinkingly, e.g. "Oh, that'll be good example of the L-shape is dead!" The poor actual player, the friend, is then left with a dilemma: do I play to make the L shape, which I was going to do anyway, or do I avoid the impression of being helped and so play elsewhere?" But we all know how easy it is to convince ourselves we really were going to do something when in reality we had only very vaguely thought about it. Maybe that happens, here, but let's imagine the player reasons, "Why should I wimp out of a move I was going to play?" and plays the killing move.
The actual player's opponent thinks, "What L shape? Oh that one. I didn't see it and my opponent is just as weak as me, so if he played it he must be accepting help. And anyway, I really need to win this game - my promotion depends on it." So he goes to the referee and says, "I think my opponent cheated. I think you should award the game to me."
So who's the cheater? The bystander, the player-friend, or the person making a potentially false allegation?
I think we'd all recognise that the bystander was the cause of the mess, but was he witting or unwitting? And that doesn't mean that either of the two actual players were necessarily guilt-free. They didn't create the temptation but did they succumb to it?
What it boils down to, it seems to me, is that ultimately we have to expect the organisers to avoid such situations occurring. That's asking a lot (especially it seems when it comes to computer hardware) but one approach is zero tolerance.
Zero-tolerance gets a bad name among some people who think it means chopping hands off for theft. In fact it doesn't have to have anything to do with the level of punishment. Rather, it means you make it known, very, very clearly, that you will not tolerate even the suspicion of bad behaviour, and that if bad behaviour occurs a sanction (light or heavy) will apply automatically, irrevocably, without appeal, and possibly unfairly - but that's the price we have to pay for the greater good.
I came across a case yesterday. In an exam for entrance to an elite university here, a rule was announced by the university that no phones would be tolerated in the exam room, and no blips would be tolerated in the case of online examinees. This latter requirement was enforced in a way that I don't quite understand but it meant that if you clicked on another program apart from the actual exam you were automatically disqualified. If you thought that was too technologically risky for you, you had the option do the exam in real life in a local school.
I don't know if anyone fell foul of a technological blip, though with an application roster of about 15,000 people I imagine there was a good chance of that. But what I do know is that a young person (18 I was told) didn't pay enough attention and took his phone into the examination hall. He put it on his desk but switched off, i.e. he was not being covert.
The invigilators, operating remotely with cameras, saw this and automatically marked his paper at 0%. The student was not accused of cheating, frogmarched out or identified. His reputation (except for stupidity or attentiveness perhaps) was essentially intact. He was simply accused of breaking a rule - "no phones." This is true zero tolerance.
I think there may be a lesson there for go (and chess). You don't get punished for cheating as such. You get punished for creating an impression that you might be. That is, of course, backed by an ultra-stark and ultra-clear warning before the game, and a written acceptance by the players and/or a guardian (which can be a lifetime one-off acceptance when signing up to join an association) that this may sometimes create unfairness. In such a regime, age seems irrelevant and penalties don't have to be harsh.
As I understand it, this sort of regime (without the computers) exists in athletics. If you miss X urine tests or Y appointments you get an automatic period of disqualification. Nobody in officialdom says you actually cheated, but you did break the rules.
