In The Most Dangerous Game, what three tricks does Rainford use to elude Zaroff? What is the outcome of each trick?

Rainsford uses three tricks to capture Zaroff.  The first one is called a Malay man-catcher.  The dead tree was cut to rest on the living tree when the foot hit the trigger, the bough that was sticking out. The tree struck Zaroff on the shoulder, but he was able to stand up and announce that he would return after having his wound dressed.

Rainsford's second trap was a Burmese tiger pit that had pointed stakes in the bottom and a mat made of weeds and branches placed on top. It was dug a dozen feet away from the quicksand that was known as Death Swamp.  It claimed the life of one of Zaroff's dogs, but Zaroff was still in the Game.

The third trick was the Uganda trick where he took the sapling and tied a knife to it with the point facing in the direction of Zaroff and Ivan.  The sapling was tied back and Ivan received its blow and was killed.

Through all three tricks Zaroff managed to stay alive but was intrigued by Rainsford persistence and cunning display of survival skills.
