Building a 10 Million Game Searchable Master Database

Comments on https://lichess.org/@/hollowleaf/blog/building-a-10-million-game-searchable-master-database/9aLSNrr3

After looking around, I found two realistic options: LumbrasGigaBase and Opening Master. Both provide very large collections of historical chess games and both were suitable for the sort of development and experimentation I wanted to do.

So your plan was to build your collection on the Opening Master database? That one that is being sold for money? You wanted to copy their database and resell it basically? It doesn't look like their license allows that.

Nope, the plan is to use it in my applications, for repertoire analysis etc... I have reached out to Lumbras to talk about licenses, and they absolutely allows for that, I have reached out to them already and have an agreement in place :)

I asked about the Opening Master database. You answered on Lumbras instead.
