What to notice at 11... f4

Black gains space and restricts the bishop before a later kingside 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. How does ...f4 change the bishop on e3?

Explain it in your own words before revealing.

Make it memorable

A wedge can silence a long-range piece.

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.
