What to notice at 43... Ra2

Black retains rook activity and the game soon repeats checks; no theoretical draw is inferred solely from the result.

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 does the rook on a2 offer Black?

Explain it in your own words before revealing.

Make it memorable

Do not trade away your oxygen.

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.
