Luke killed Welk by grabbing his arm and killing him with his own lightsaber. Grappled Abeloth, which perhaps the most impressive hand to hand feat he has.
Don't remember Luke ever using pressure points though or any statements of him being great hand to hand combatant. But Luke is more accustomed to fighting, when he can't feel his opponents through the Force due to experience with Yuzhaan Vong.
Side with Luke but only because don't know much about Sidious unarmed combat skills.
