>It sure got strangled. Look at 21... e5?? and what happens after.

That was a special "trapped piece" case (all programs do not understand)
and has nothing to do with a) first block the position and then b) start
a long prepared king attack. Not easy against Rebel which was my point.
Evidence: the last 25-30 IM/GM games Rebel played.

After 8...c4 black is not lost at all. The real trouble started later in
the game.

No few games. Each game contains 30-40 moves (positions) and 3-4 crucial
positions that reveals important information. For Rebel that is 25 x 4 =
about 100 crucial positions and hardly any stranglehold seen.
