At least Piccolo know to tactician when he's fighting
Nail and Kami wisdom help a lot
Zoro vs Ryuma
- a balanced fight until Zoro took the upper hand by exploiting the advantage of the ground around him (the falling roof cut by Ryuma)
=>
a decisive tactical move
Zoro vs Pica
- he comes up with 4 tactics to cut down Pica before picking the best one : Tactics n°5 (which is none other than the title of chapter 778).
- with this tactic, he managed to beat Pica while having anticipated the fall of the debris of the golem which were then repelled by Elizabello's "King Punch"
=>
a decisive tactical planning
Zoro vs Gifters
- not a real fight but after Luffy got knocked out by Apoo, Zoro decided to retreat and avoid fighting as much as possible in order to minimize the damage taken and keep their chances of fighting Kaido.
=>
a tactical retreat
See ? Most of Zoro's tactical moves make him win his fights so how can you pretend that he doesn't know "to tactician when he's fighting" ?
As far as wisdom goes, if you've at least read One Piece, you should have seen the numerous times Zoro acted as the wise man of the crew (mostly in a vice-captain role).
Moreover, the incantations he recites before launching a powerful attack are not there for show ! He must have learned them in his village probably from the same old man who taught him the term "Sunacchi" : Shimotsuki Kozaburo
