basically you want to do 3, the sway and then do 1,1 but you have to hold down the 3 the whole time and if it hits it will give them a really long stun but the infinite is when you hit them way on the back/side and you hold forward to go into the big dempsy role thing and then you do 1,2,1,2,1,2 infinitly until they die. hope that helps if you have any questions just reply back
