During combat, dovakhin pushes with the sword or axes like a punch and then slashes. How do you push enemies away... Is it just the trigger sequence or what?

Since the game was designed on gamepads, its a combo more or less as subzero freezing balls, it all comes in the 666 pages Skyrim guide

i guess it's just the distance to your enemy

if he is too close, you cannot do a full swing, so a push
