Boris's verdict

The Overextender

“You play with fire. Beautiful attacks when they land. Let's make them land more often.”

CRITICALCosting ~120 Elo

You hang pieces between moves 12–18

7 of your last 23 games lost material in the early middlegame. Mostly undefended knights and bishops after pawn trades open files.

02 · A grandmaster reviewing every game with you

Boris doesn't just call out blunders. He teaches you through them.

Every mistake in your last game becomes a lesson. Boris explains why the move you played failed, what threat you missed, and what to look for next time. In plain language. No engine output to decode. No diagnostics jargon. Just a coach.
