According to the trolls here:
Prof. van den Herik does not know about game theory,
GM Sveshnikov did not know about chess analysis,
and tygxc does not know about either...
Suggesting that Prof. van den Herik had not had his morning coffee when he included your quoted definitions in his paper is hardly saying he doesn't know about game theory. He is in fact eminent in that sphere.
Similarly suggesting that Sveshnikov had taken something stronger than coffee when he made the remarks you quote does not detract from his abilities in analysing chess at a practical level. He was reputed to have a considerable talent for that.
We can agree on your last point.

Getting three things right in a row is amazing.
