Minecraft wiki entry for Player_versus_Player, associated text: It is said above regarding running in traps (refer to "Diamonds aren't the key to victory") being a tactic that will fool the enemy, this makes it a rather effective attack. Always use psychology as a weapon! When running into a row of tripwires, the enemy might find it as a suicide attempt and not as a double trap, although not very likely since most people will tend to just chase you. However, if you have a circuit that makes it so that the first time somebody runs through it, there is a chance your enemy may think that it's a dud or just a scare for the raiders. Once they step over it, though, the trap activates. This makes it useful since it can make the enemy think you are intending to run away when you're instead luring them into a death trap. If you have any type of invisibility potion or maybe you are just very good at not being noticed, you can easily lure the enemy away from your actual position, then jump-attack them when they are least expecting it. This can be the key to a neck-and-neck battle, where your enemy's equipment is as good as yours.
