Hi Vladimir,

in FCP at the moment 3750 games on i7 with 40 moves in 10 minutes played.

I am using SmarThink without endgame databases because with endgame databases more of such games you posted before will be the result.

On weekend I checked my current database version before I updated to FCT League 2.

I checked games from Smarthink and DiscoCheck (engines produced problems) again.

I found 7 games from Smarthink (without endgame databases) engine lost in clearly draw position (example KR vs. KR) and corrected the games to draw.

Found 6 games I overview before ... DiscoCheck made draw in clearly won Position in endgames (50-moves rule).

An old SmarThink Problem, reported here after release. In my "Download games by Players" selection I added some of such games in a zip file. End of the page I create a bug Report for tested engines.

The best way in testing SmarThink ... not to use endgame databases and to check game results with KR vs. KR.

Best
Frank

Hi Gabor,

your opinion should be more right as my.
But I will have a clear database for the Elo calculation.

Example:
MinkoChess ... lost over 40 games on time 2-5 moves before mate. If I not corrected the games Elo goes up and for the opponents which normaly lost the games ... Elo goes down. I am thinking this one can not be correct.

More easy to create such a work we do is to Play with "resign = on". But with resign = on I can't create stronger stats.

Again ...
Normaly your opinion is more right ...

Other example:
Each game with draw up to move 20 I replayed, same for games longer as 299 moves. Same reason ... will have a clear database!

Best
Frank
