What to notice at 22... Qb7

The pawn gains a useful square for the rook before advancing again later.

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. Why can an open file be useless?

Explain it in your own words before revealing.

2. How can a pawn support a rook invasion?

Explain it in your own words before revealing.

3. Must a rook remain on its original file?

Explain it in your own words before revealing.

Make it memorable

Road, doorway, destination.

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.
