Straight blast (I personally prefer tiger claws instead of punches) is good as a pressure technique to make the opponent move backwards and lose balance. We can then terminate the fight with elbows, knees or take downs for a close distance.
But before that, as a very first step, we will probably need an entry (usually some kind of destruction or interception: e.g. edge of hand, crash helmet, skull and crossbones) which would allow us to move in closer to the target in a safe(r) manner.
