What to notice at 43... Ng4+

After Kh3, ...Nxe5 follows. This is a concrete discovered-check mechanism in Black’s winning conversion.

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 does ...Ng4+ gain time to attack Be5?

Explain it in your own words before revealing.

Make it memorable

Open one line; strike another target.

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.
