IF you block with your forearms or elbows you can hit in full contact range without even moving.

You can also hit off the same side you just blocked with faster than blockig with one then throwing the rear becuase the one you just blocked with has less distance to travel so its faster ad you can score.(you wont be doing any damage).

Or if over the top of a jab with your fist vertical in a jab and your elbow down, you can block and strike if you are in opposite stances so you go across his jab from the outside to his head simultaneously blocking and striking.






If you block with your gloves or your wrist area anywhere from their
forearm to their glove you have to move in to be able to make any contact.

So by dancing the correct timed dance you can deal with them out of contact range or in contact range and that can upset rythm too.
Yours as well as theirs if you dont know what your doing and havent soaked up the limits of what you can and cant do with both distances with bridging them both on attack and in defense.

Sometimes remaining in contact with an arm you just blocked as you move in, can be a big disruption in that process too. Follow it and strike off it,or follow it home and move it so his balance is compromised for a fraction of a second.
Depends on if you are in side his retracting arm or outside it. Its down to your other arm against his other arm then. but you got the control, if you move his retracting arm towards his centre or up he cant throw the rear clean but you still have to be ready for it after you land.
Thats more for disruption of his timing and gaining you the next real blow off a full inside position than just gaining a point.
