What is a mate in 4?
Longer forced mates from real games, usually a sacrifice, a king hunt and a precise finish. Every branch is mate — finding the order is the work.
How to spot it
Divide the line into phases: strip the shelter, drive the king, deliver mate. Verify the most stubborn defense at each fork before starting.
What this set trains
Deep forcing-line calculation with a guaranteed payoff — the best stamina training tactics can offer.
