Forced moves have strong appeal to beginners. I have noticed they will always check, when they see a check, or choose another type of forcing move, when there is one. I smile when a novice checks me and allows me time to improve my King's position. Analysis is essential to determining whether such moves are beneficial. All forced lines must be analyzed to some kind of conclusion.
Some people are faster at analysis, because they have innate talent. It is often not possible to defeat a player with a faster "processor," so to speak, except in a long or correspondence game. I consider myself slow at analysis, and that is why I prefer long games to blitz. I do not think it is possible to improve much at blitz. One has the hardware or one doesn't. I do think it is possible to get better at long games, in which both players have adequate time to prioritize and then analyze the possible moves.
