Test Position - wrong eval score

[MikeGL]

Very few engines can handle fortress assesment correctly, as already pointed out by other members here.

below position was shown by an IM who posted this in youtube

[d]8/7K/1R6/k2p3b/Ppp5/1p1P4/1PP5/8 w - - 0 1

Most engines got the correct line: Rb5+ Kxa4 Rxb4+ Kxb4 c3+ Kc5 d4+ Kd6 Kh6 Ke6 Kg5
but gives the wrong assesment and shows black is winning because of +2.00 or greater than +3.00 in eval score. But it's a fortress draw.


Also, below position is another fortress from one of his actual blitz games that was analyzed in youtube against a GM.
This was a fortress draw and was missed by a GM who didn't hold the losing side.
