A chess bot that plays at your level

Play the best move and the bot gets stronger. Slip up and it eases off, so every game stays a fair fight.

Every move you make is graded, from “best” to “blunder”, by how much it changed your chances of winning.
The bot's level (1 to 20) follows your play. Best moves push it up; mistakes bring it down.
