In the diagram position Black has just set up a mate threat with 19.Qh3 . but I can see your eyes are already on the Ke8. Let's do it - can you calculate everything in your head?
After 21.Bxh6! (diagram) Black can't take back, but after 21.g6 White needs a brilliant idea to prevent his attack from going nowhere. Can you deliver?
Attacking is usually easier than defending, especially with short time controls. In the diagram position White kept on pressing until Black finally blundered, a typical rapid drama - I wish you fast entertainment!
