What to notice at 35... Qd8

Fischer’s 36.Bd3 changed the bishop’s diagonal shortly before the tactical exchanges on f6. White improved coordination rather than making an immediate pawn advance.

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. A bishop has a better diagonal available before the pawn break. How would you apply “reposition a bishop before opening a wing”, and which defensive reply must you check?

Explain it in your own words before revealing.

Make it memorable

Aim the bishop before opening the door.

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.
