Just learning the rules.
Plays principled but often misses tactics. Great if you're brand new — you can win her on technique alone.
Trains: Basic principles — develop, centre, king safety.
Recommended if: You're new and want to practise fundamentals.
Local club player.
Plays a sensible repertoire but blunders one piece a game. Perfect for working on basic tactics.
Trains: Stop hanging pieces — club-level tactics discipline.
Recommended if: You blunder a piece most games.
Sees three moves deep — at least.
Calculates tactics well. Don't hang anything or she'll punish it. Use slow positional play.
Trains: Tactics discipline — punish loose pieces.
Recommended if: You miss simple tactics in games.
Attack first, ask questions later.
Pushes pawns toward your king, sacrifices when in doubt. Defend solidly — when his attack fizzles you'll be up material.
Trains: Defend attacks — survive wild kingside pushes.
Recommended if: You struggle against attacking players.
Boring? Yes. Hard to crack? Also yes.
Trades pieces to a drawn-looking endgame and grinds you down. Avoid trades, keep pieces on, attack his king.
Trains: Avoid passive trades — keep pieces and create play.
Recommended if: You trade too much and end up worse.
Stockfish at near-full strength.
No mercy. Use this when you want a real test — the engine will exploit anything sloppy.
Trains: Calculation punishment — no sloppy moves survive.
Recommended if: You want a serious test at near-master strength.
