G.O.A.T.
One thing that confuses this discussion is that, in chess, "strategy" and "technique" are nearly synonymous, whereas in tennis, they are not. That is, someone can have a good backhand but not be a very good strategic player; however, it's not possible to make good use of your rooks but have bad strategy. Well, I suppose it probably is possible to use some pieces better than others, but the distinction is not going to be as marked as in tennis.
