Switching to intermediate chess puzzles requires a shift in strategy: you are no longer just spotting a lethal strike, but active engineering it; then you make it happen. Be ready for sharp, fast-paced tactical action as you work through tens of thousands of such exercises. The intermediate chess puzzles already step beyond a single move (compared to mates-in one), most of them are the two-move sequences, with unexpected effects sometimes, like fork or sacrifice, and they form a perfect ground for the toughest levels — the hard chess puzzles, the combinations of 3 and 4 moves before the checkmate. Intermediate puzzles are where the chess adventures begin. Here, you’ll encounter canonical Arabian checkmates, the lethal teamwork of a rook and a knight, and deceptively casual back-rank mates — the classic highlights made famous in "Bobby Fischer Teaches Chess" book. Packed with real-world middlegame scenarios, X-ray attacks, and dramatic sacrifices, it shall sharpen your tactical calculation to a razor's edge.
