Desperado was one of my first 'favorite chess terms'. When I first heard this term, it helped me to find the right moves in some fairly complex positions. For people who don't know, when a piece that is attacked but does not move and another piece is attacked instead, the piece that is counter-attacked can become 'desperado'. What this means is that when a piece is counter-attacked, it can often do whatever it wants (often take something) because after it moves, if it is taken, the first piece that was attacked is still there for the taking. Keeping this in mind, moves can often become very forcing. Best of luck!
Of course this is just a general rule. Different positions can yield different situations as always. If this is still unclear, feel free to message me with a question.
