Game database public?

#1

I have begun to notice an increase in opponenets crushing my "prep." As an open source website is it possible for opponents to see what my most common moves are during a live game and play what I struggle with the most? Maybe its just coincidence, but its causing me to rage quit.

It is possible, yes. Consulting books or databases, including your opponent's games, is against the fair play guidelines outside of correspondence games.

Yes the games database is public and you can download it. But looking at your last several pages of games, you play all fast time controls and almost never play the same person twice. The one guy you just finished with where you played four games, you split two to two. I find it very hard to believe that someone is going to study so hard as to prep for someone because they're going to play a couple games of online 3-0 Blitz for nothing. Highly unlikely.

What I have been seeing is a delay once the game starts. Possible that opponent plugs my user name into a database checker and can see what lines I stuggle against. My "prep" is limited but it seems like almost all of my recent opponents "know" what to avoid.

As a practical mater, nobody knows how to do that, let alone all of your opponents knowing how to do it. Sorry to disappoint.

(Personally, I think the Lichess ban on databases is unnecessary to preserve integrity of the game, unlike a ban on engines.)

that delay is not long. I really dont see how they could open/load database do quick analysis what you do and plan response before system would abort the game and give you opponent a warning

My guess is that its AI. Just like looking at your own database. Something just feels off when they dont play obvious moves.

If you go to the database download page, you'll see it's no small thing. Every month is a massive download. PS, I have a lifetime of experience with databases. They'd need an additional server sitting there just to handle the database work, (I have that, but not for chess), not to mention terabytes of disk space to hold it. Now they'd need to do regular maintenance in order to keep it up to date, and let's not forget they have to write analysis code which can pull up all your games and boil that down into useful "prep" within enough time they can still use the remainder to play a 3-0 game. And again, all this work so they have a better chance in a 3-0 blitz game for $0 against random opponents they'll never meet in a lifetime. Come on now? And we're not talking about one person doing this, you're suggesting it's widespread. Puh-leassee...
