What to notice at 24... f6

Kasparov’s 25.Nd7+ was answered by ...Rxd7, then 26.Rxd7. The new rook position helped sustain the queen-and-rook attack.

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 knight check can force a rook away from a defensive file. How would you apply “use a knight sacrifice to draw a rook off its line”, and which defensive reply must you check?

Explain it in your own words before revealing.

Make it memorable

A knight can pull a rook out of formation.

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.
