Mate in Four

Mate in four is a calculation workout: a forcing net woven from checks, sacrifices, and threats. Only forcing moves keep the tree of variations small enough to see to the end.

How to spot it: identify the mating pattern you're driving toward, then force the king there one check at a time. If a line fizzles, return to the branch point and try the next forcing move. Patience and clear visualization win these.

Now spot it yourself

A real position: find the move. This is exactly what the drills in the app do, banded from beginner to expert.
