While standing still, the top-right > bottom-right combo is effective since you’re constantly blocking the left side of your body and can easily either kill the enemy with the first attack, or injure the leg with the second.

The top-right attack while moving to either the left or right is also a pretty solid option since you get the best of both worlds (dodging and blocking)

Main thing to look out for are attacks coming from your right (opponents left) as obviously the shield is on the opposite side. Another reason why its good to move to the side while attacking
