What to notice

What happens if you look across the board first?

Compare the move played with the suggested move at Q10. Step through each idea on the board and see why one creates a better result.

This is an example. Personal lessons will use moves from your finished games.

See the coaching approach

A better move is useful only when you understand why.

The suggestion

Q10 · stronger move

A coordinate tells you where to play. It does not tell you what to notice.

The lesson

“Before you defend here, look across the whole board. Can you threaten your opponent’s weaker group first?”

Try both ideas on the board, see what changes, then return to the move from your game.

Clear, honest coaching

See the moves behind every explanation.

Each lesson keeps the original position in view, so you can check the idea on the board. When a position does not support a clear answer, Nesaroa will say so.
