Bakou found his opportunity, the boy was getting dangerously to Bakou and as the Uchiha would simply commence his little cartwheel, Bakou would slightly bend over his body so that the Rocket feet would propel him at insane speed through the extremely small distance between the two fighters. Left fist ready to deliver the final blow, targeting the chest of the foe. Whether or not the kunai would be thrown or not, the intense speed of Bakou would inevitably allow him to dodge if the attack were unsuccessful and the sudden change of position would also likely pose a problem if the kunai were to be launched earlier. Nonetheless, the position he'd hold the kunai on his right hand would allow him to block the enemy's kunai if it were to target his head or neck and his arm readied to punch the lad would also cover the entire left side of his head.
This was a decisive moment, if the Uchiha were to manage to dodge, the fight would rage on and maybe even turn the odds or if he were to take the hit head on, it'd be over. Blocking would be mostly impossible in this case due to the intense speed and even so, the fist would only detonate a couple of seconds later while Bakou can simply refer to an explosive tag to keep the foe busy or even finish him off.
