What to notice at 17... Bxe5

The sequence ...Nxe4 Qxe4 ...Bxe5 dxe5 leads to ...f5 and active Black play; Black wins.

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 Black change White’s attacking army with ...Nxe4 and ...Bxe5?

Explain it in your own words before revealing.

Make it memorable

Remove the hinge before the door opens.

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.
