why not do them all and make a comparison, is it too time consuming?
I posted over in the "Help" forum about being accused, at the end of a series of four games with the same user, of using a program. Someone suggested I post here and see if Zygalski would analyse the games. I appreciate that I, at 1800 or so, am not quite what he was after, but it would be interesting to see how computer I was in those four games.
I should perhaps mention the background, which is that I've been off the site for the best part of a year after my son was born in October 2012, and took on far too many tournaments when I came back. As a result, I was playing extremely badly, and my rating had dropped somewhat (to around 1600). My opponent was rated almost 2000 at the time of the games.
Zygalski - if you would be kind enough to look at these and put them through your machine, I would be very grateful, but I don't want you to feel obliged.
I think the games are quite interesting anyway - especially the last one, with the very unbalanced material, and the K+P ending with equal material. And odd that the Alekhine leads to the win of a pawn and conversion in the ending, and the Caro-Kann to wild imbalance and attacks on opposite sides of the board.

It's a communal character flaw we all share to one degree or another.

I told him if I was really willing to use an engine that there's no way he would have gotten a half-point.
That's hands down the most ridiculous one I've gotten.

A fairly decent match rate, but far below human-achievable thresholds.
Although the sample size is about 1/5 that which this method was deigned for, from what I can tell from these games it is unlikely an engine was used & if it was, then it certainly was not used in any blatant way whatsoever.

Well I decided to analyse the current top player on the site to see how engine-like their play is.
The games were chosen in a transparent objective way & met the usual game selection criteria.
I looked through the completed game history for TheBigKat User 653175 and analysed the most recently completed non-thematic games with 35+ moves where the opponents were rated in excess of 2000.
All database moves were excluded from analysis.

When you follow the full methodology both the very best pre-1990 correspondence World Championship finalists & current OTB Super GM's all have match rates around
Top 1 Match 60%
Top 2 Match 75%
Top 3 Match 85%
+/- a % or so for each T%.
No single benchmark has ever been published for an unassisted human player where 20 objectively chosen games yielding 600+ non-theory moves have exceeded all 3 of the above T-figures.
