Trap
A maneuver that at first glance seems to give the other side a certain advantage, but in reality lures the opponent into a position that is bad for them. Here, for example, are two opening traps:
Playing for a trap
There is, however, an important difference between these two traps. In the first case, had Black played 6...Qf6 instead of 6...Ne5, White's whole attempt at the trap would not have paid off, and they would have had to settle for a worse position. In the second case, Black was pursuing a plan of steady development, setting the trap only in passing.
Hence the conclusion: playing for a trap is not advisable if correct replies by the opponent can leave you with a worse position, and a trap is worth setting when, even if it is seen through, it will not worsen your own position, or when the position is already so bad that only a trap can offer saving chances.
