Best punish upclose for spin is 2, 1, smoke bomb. If he blocks it, try your hardest to d1 and get out of there. Never jump in on him, and don't try to get cocky if you have the life lead. Additionally, a thing that Kungs usually catch me in is if the have Xray and I sweep or d4, they can use armor to take the blow and severely punish you, so be careful when using sweep and d4 upclose and he has Xray, there are better options you can use like d3, and d1. Always try to block after a mid screen whiffed Smoke bomb. He can get in pretty easily and isn't afraid to do so.
