16... Na5 · White to move

What to notice at 16... Na5

Follow d5, cxd5, Bxh7+ and Rxd5. Each operation clears or uses a line for the next piece.

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. Does having many pieces near the king prove an attack works?

Explain it in your own words before revealing.

2. Why can an intermediate check matter?

Explain it in your own words before revealing.

3. How can the defender disrupt teamwork?

Explain it in your own words before revealing.

Make it memorable

One problem, several helpers.

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.
