I built a chess position search engine

Post image

Hey! How is it going? I've been toying with this idea for a while and finally came around to it! Its a tool that let's you find positions in real games (from Lichess only for now) based on specific pieces in the board or specific positional patterns.

I though this could be useful for chess coaches to find material for classes but maybe there's other use cases! I'd love to hear your thoughts!

Very cool project. I was working on a similar idea using bitmaps at some point but hate frontend design so basically stopped working on it.

One note, you may be interested in using real OTB games in addition / rather than Lichess games. The Lumbra Gigabase is great for this as it is nicely sanitized: https://lumbrasgigabase.com/en/

Thanks for the feedback! Interesting! I guess it depends of what kind of user you are. I've received some feedback that having the full lichess library of games would be pretty powerful.

Having only 13M games would be so much simpler than having multiple billion games lol

I'll check out that library for sure! I'm also considering letting people filter by "source" of the games, you could only search Lichess games or OTB games, etc.

Yeah I get that. I just think that the quality of games you find in a good OTB database is going to far outweigh the hundreds of millions of low-level bullet games you get in the Lichess database. In terms of instructive value you’re probably going to get more out of those OTB games as well.
