Yes, D&D has references to actual time units, like a turn taking 6 seconds. But that didn't have any real effect on the gameplay. If they said one turn equals 60 seconds, the game would have played the same. It just would have left players wondering why they can only move 20 or 30 feet in 60 seconds, as an example.
you strategise multiple paths of movement and eliminate choice with each opponent turn, you have to react [...] to the unfolding combat.

Well, yes, because you literally extracted my definition of chess (TB games) and then appended my out of context conclusion about real time.
