Ah, the bullrush. A tactic of desperation if ever there was one. Even before the slide became obvious, David began moving to his right, preparing to sidestep the rush and use the man's momentum against him. When it turned out he was sliding instead of a more conventional attack, David's right foot was already out of harms way and a simple sliding of his left foot removed it from danger as well. As the man's momentum carried him closer, David stepped forward with his right foot and dropped to his left knee, driving his left fist straight down toward Ahmad's stomach, allowing both gravity and his own muscles to power the blow.
