What to notice at 24... Kh8

Keene’s 25.Bg7+ forced a bishop exchange before Qxg7 mate. Trace the queen, bishop and rook lines to see how each exchange changed the final geometry.

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. A checking piece can invite a capture exactly where the queen wants to arrive. How would you apply “force an exchange on the mating square”, and which defensive reply must you check?

Explain it in your own words before revealing.

Make it memorable

Offer, recapture, verify the net.

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.
