dead draw position that is misevaluated by any modern stockfish version as +1.3..1.7 in favour of black

Two pawns down but dead draw.
White bishop prevents two black pawns from moving.
In most cases this game ends in 100-150 moves after this point.
I hope this helps to make stockfish even stropnger)

It takes about 100 moves (200 plies) for stockfish to realize this is draw.
Initial eval is +1.5..2.0 in favour of black

Initial eval is +1.3..1.6 in favour of black but after 20 moves (40 plies) stockfish realize this is draw and reverse analysis confirms this.
Static eval with long time control easily reaches 0.93..1.2 range with 40GB TT but after TT runs out it again boomed to 1.4
