Having reached this point, I then asked:
||zanzibar: As concerns TWIC:
I’m going to post a little more on the topic, but I’d like a little clarification first.Can <chessgames> point me to a specific example of a TWIC with a tournament that you consider substandard?I tried looking for high school matches, or very weak tournaments and haven’t found any such examples.Of course, TWIC is a huge project, and I admittedly only looked at a few downloads with this particular goal in mind.
To which <chessgames> replied:
||chessgames.com: I took a peek in the latest TWIC issue and just for example, the “6th Arco Christmas Open” is not particularly important. There are a few masters there and we’d be happy to take some games that might have a pretty combination, but all too many of the games are like this one:[Event “6th Arco Christmas Open”]

[Opening “Scotch opening”]

I would never disparage beginners or poke fun of their poor moves, but I just don’t see the purpose of immortalizing a game like this in the main database.From time to time somebody will want to save a game like this for reasons somewhat personal to themselves, and that’s fine. As I intimated, one day we plan on offering that as a option.
Let’s use SCID to annotate this game, which is between an unrated player and a 1300. For the record, here’s the annotation parameters:
Clearly given the low rating and lack of rating, the play will be expected to be error prone. But is the game totally irredeemable? Not really, as I found an interesting position at Black’s move 15.
Black played a move, 15…Re2 which is annotated as a blunder by SCID, even though it evals to -10.41, which is completely winning (and better than the material B+P lead). The reason it’s marked a blunder is because there is an unplayed forced mate (an M-10). It’s my opinion that this mate is very challenging and instructive.
And so, despite having low rated players we have a high level, challenging position. In fact, to balance the material hole White is in, I cooked the position by adding the bishop back on the board to make an interesting problem:
||zanzibar: Here’s a tactical from a cooked position:
Hint – the best move doesn’t involve a capture on h6, at least not initially.
There’s a lot of nice little puzzles spinning off in various sidelines. What I like about the position is how Black basically utilizes all his pieces, and I do mean all (hint, hint) to prosecute the attack.
Cooked from a game suggested by <chessgames>!
<6th Arco Christmas Open ITA | 2015.12.30 | Montori, Giorgia — Rigo, Nicola (1307) | 0-1>
Now, do we want such games in the database? Probably not, I would agree. There probably should be some rating floor put in place in general. Certainly, not having a rating would suggest exclusion. On the other hand, many GM simuls involve unrated players, and somehow a large number find their way into the DB.
Additionally, I think that having FIDE id’s for both players make these games easily manageable if they were to be included in the DB.
