What to notice at 23. Kh1

White makes a quiet king move in a tense French position; the eventual game is drawn.

A legally replayed historical example, not a claim that every move is best. A game’s result does not prove every defensive position was lost or drawn.

Your thinking first

Name the signal, choose a plan, and test the opponent’s most challenging response.

What do you notice?What is your plan, and why?How could the opponent resist?

Recall and explain

1. What general precaution does Kh1 provide before further central play?

Explain it in your own words before revealing.

Make it memorable

Leave the line before the check.

Teach this to a friend in one minute. Then return to a different example and look for the same signal without being told its name.

Reflect and revisit

This is your self-assessment, not an engine grade or a promise of mastery.
