 Beats alter-nately with both elbows
   The boxer throws both of the elbows, left and right alternately the same as the trick in  SOK FAN NA (SOK FUN NA: strikes the front elbow) then steps the right foot towards the opponent, if he escapes by stepping back follow him by throwing the left elbow by turning the body back and strike the opponent's chain or the left ribs. This trick is used for attack defense or escape.
To protect throw the knee to the opponent's rib.
If the boxer is a left handed fighter reverse the descriptions from 
Right to left.
