What to notice at 20... Kg8

Kasparov’s bishop travelled from b2 to g7 with 21.Bxg7 after central exchanges cleared its diagonal. Its distant starting square had concealed a direct attacking role.

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. The opponent’s king-side pawn move creates squares on your bishop’s diagonal. How would you apply “use a long diagonal to punish a king-side commitment”, and which defensive reply must you check?

Explain it in your own words before revealing.

Make it memorable

Distance does not weaken an open diagonal.

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.
