Kh8 instead of capturing the knight, White is still attacking and will gain material (because sacrificing will be the only correct defense for Black.) Leading to an easy game for White. But now that Black has fallen into our trap, the rest of the combination is very much forcing and leading to mate! But it's still a complicated sequence, stay sharp!
