light climbs out of a gravitational well, such as a BH.

I thought the whole thing about BH's is that once in its gravitational pull...........nothing can escape.

Provided the beam of light did not cross the event horizon it would be red shifted & deflected by its close encounter with the black hole but would live to tell the tale , so to speak.

Of course if it crossed the EH, game over, from our point of view anyway.,

True. I saw a tv show called "10 ways the Earth will end". One was being swallowed by a BH. It wasnt too scarey until the last few moments. Crossing into the EH is indeed "End Game".
