I think much of this discussion has become unproductive, since it was initiated and revolved around the incendiary characterization of this tool as “cheating”. It’s an unfortunate word choice, which has framed a lot of the discussion around personal attacks.
I think, by definition and convention, any use of the SE is not “cheating”, since it is a feature built into the site. If it were against the rules to use it, it would simply not be offered as a feature, but that’s clearly not the case, since it has been part of the site for years. However, I think it is valid to question and debate whether it should be available as a feature.
Ok, so here’s my elitist, condescending opinion on the matter…
Ultimately, to me, the issue of whether the SE (in its current form) influences games is largely theoretical and a matter of principle, rather than a major practical concern. Frankly, I don’t care if other people want to use it, and I completely support maintaining the current status quo. In fact, the only thing that I would strongly advocate for is to not upgrade the SE to perform better (e.g., by applying strong AI).
My position is precisely because the current SE is terrible, and offers little useful advice to SDK-level players and stronger, and I’m not so sure if it’s actually very helpful for DDK ranks either. I don’t think any SDK players take the SE advice seriously, and would only look at it for entertainment, rather than for useful advice.
However, imagine what could happen if the SE was upgraded to use a strong engine like KataGo or LeelaZero. The SE will evaluate not only the current position, but also hypothetical positions that one can setup with variations. Thus, a player could use SE to judge which of a set of potential moves is best, or to check if a tenuki is safe. Even if checking only the current position, a sharp change in the estimated score could provide a helpful hint that the opponent has left a weakness that should be exploited. Of course, with the current SE, it’s too atrocious to actually provide such helpful advice, but if it were to be upgraded with a strong AI, then it could be reliable enough to offer advice.
