About OpenVary

OpenVary is a small, independent library of chess opening guides. Each guide explains one opening or variation line by line: what both sides are aiming for, the main line written out in PGN, the critical alternatives, the mistakes that decide club games and how the other side should defend.

We would rather publish a few guides that are genuinely useful than hundreds of thin pages. Every guide uses the same structure, so once you have read one you know where to find everything in the next.
