look, lets say that kakashi starts the fight with a katon. Im not really sure, but I believe that shino's insects could tank it for him. that's about 10% (at the minimum) of pts kakashi's chakra gone. shino then counters, kakashi obviously dodges, but has shino different set of insects emitting a chakra that looks exactly like shino's from behind kakashi. kakashi takes it into consideration that that isn't the real shino, so he doenst really fall for the trap. he then decides to pull out his sharingan. kakashi then goes for a blitz at shino's legit body, which then dissolves into insects (he can do that, btw. people think its a filler thing, but he did it in the manga), which try to surround kakashi, so kakashi pulls out an explosive, and gets the **** outta there. since shino's insects can sense his chakra, his hiding wont work for long. they try to crush kakashi, so he pulls another katon (since he had only about 90% of his chakra after he used the 1st katon, and now he had his sharingan activated for the whole time, and then used another katon, he has about 55% of chakra left. im estimating, btw). he sees shino's real body again and goes for a chidori. shino could use his bigger/stronger insects to stop kakashi in his tracts, or turn his body into insects again, but either way, kakahsi gets open, and has about 20% of chakra left. his sharingan deactivates, and he catches his breath for a moment. that one moment is his doom.
