Drill your openings with guided move validation
Knowing your openings cold wins games at every level. Chessyi includes a dedicated opening practice mode with dozens of named lines, from the Ruy Lopez and Sicilian Najdorf to the Queen's Gambit and King's Indian.
Practice mode validates your moves against the line, offers hints when you are stuck, and can auto-play opponent responses so you can drill your side of the repertoire repeatedly.

What you get
- 70+ curated opening lines with descriptions
- Show mode to learn the moves, practice mode to test yourself
- On-board arrows highlight the expected move
- Instant feedback when you play an alternative
