Unbeknownst to Albrecht, Severus Lycanne was also holding back as well. For one, he was surprised that Albrecht was actually pretty weak, and it gave him some form of confidence to keep on attacking while disregarding his techniques. Had he been a little bit more careful, he would've won the match in an instant.
Since his judgment was clouded with his unconfirmed confidence, it didn't even occur to him that Albrecht was also holding back. Then again, he could more or less guess the difference in their levels, that's why he concluded that Albrecht was using his full power— and that his achievement of defeating someone from the Lycanne Tribe was a mere fluke.
With a slight grin, Severus finally found another opening, and he decided to finish this match once and for all. Increasing his speed up a notch, he delivered a powerful kick right at Albrecht's face. If the kick were to connect... then Albrecht would be instantly decapitated.
