Mate in Three
Mate in three stretches your calculation to a full forcing sequence. Every move should be a check or a concrete threat, so the opponent's replies are forced and few: that's what makes a long mate calculable.
How to spot it: hunt for forcing moves first (checks, captures, threats). Follow the most forcing line to its end, and if it doesn't mate, back up and try the next most forcing move. Visualize each position clearly before moving on.
