here are some of the main ones:
You can't push the opponent off the mat to gain a point.you must try some sort of technique and only then if the opponent is off the mat you get a point or more points depending on your executed technique.
No more silly clinge based on lottery draws.if the bout ends up in a draw then the criteria for the tie-breaker winner is first by the high point technique scored by the wrestlers and second by the last point scored by the wrestlers. no more silly lottery based clinge.
No more excessive defending to shut down your opponent .you get a warning followed by a final caution with a deadline to either score in 30 seconds or else you lose a point to your opponent.
A take down (khak) is awarded 2 points instead of 1 point.and high techniques (such as derakht kan , salto ,fito) are awarded more points than before to give incentives to wrestlers to try those fantastic techniques that pretty much vanished under the old rules.
And TM Iran will go against India in about 90 minutes. a win by Iran and Iran will play in WC Final against most probably Russia in about 8 hours.
I simply love Wrestling.
