Alekhine Defense Kmoch Variation Puzzle (Rated 1633): Win Material — Hanging Piece Refutation
This opening puzzle shows a classic tactical refutation where one loose piece and an exposed king create a decisive material gain. White’s bishop has invaded deep into Black’s position, but it is not fully supported, and Black can use the king to eliminate the threat while keeping the initiative. In practical classical chess, these positions reward accurate calculation over general principles, because one tactical shot can turn an active attack into a winning end to the sequence.
