What this lesson explains
This position is from Edward Lasker against George Thomas, London 1912. Black's king is castled, but your knights on e4 and e5 are close, and your bishop on d3 aims at h7. This exact position is rare on Lichess, but the idea comes up again and again.
Qxh7 check! White gives the queen. After Kxh7, the knights chase the king up the board.
After Kxh7, Nxf6 is a double check, and the king walks forward. Check after check, h4, g3, Be2 and Rh2, drives it all the way to g1. Then Kd2 is a discovered checkmate.
