enemy edge pawn as part of own king shelter

[beram]

Theme 'enemy edge pawn as part of own king shelter' has been mentioned earlier
http://rybkaforum.net/cgi-bin/rybkaforu ... pid=573199
and now I have a new example from a recent match between Komodo 11.2.2 (ct 0) and Houdini 6
At move 31 ..Houdini 6 played a5 and starts a king attack while his own king is sheltered by the white enemy pawn on h7 and his strong black bishop on g7
Komodo 11.2.2 doesnt see the black advantage not even after 8 minutes at dept 45 and would continu with f7-f5 (31...f7-f5 32.Lh3-f1 Lg7-f8 33.Dd6-f6+ Lf8-g7 34.Df6-d6 = (0.00) Diepte: 45 00:08:39 8455MN)

The edge pawn shelter is a most notable idea by Lyudmil Tsvetkov, and subsequently it was then successfully incorporated into Stockfish. That was a few years ago. Komodo is lagging badly in this area.

[Nordlandia]

Does edge pawn gain negative value, since it shields enemy king?

White's better off if h7 pawn vanished from the board.
