Sting SF 9.8 update

Sting thinks this is winning for black, but actually it's dead drawn.

Sting doesn't think but you should do it.
In the rules of chess there is no words about scores. Engines return scores but they don't interpret it. Scores can only help you in the correct interpretation.

Sting evaluates this position much worse than some other engines. So badly in fact, that it could deliberately aim to reach this position for black, only to find it is a draw.

I would have thought that's worth knowing about.

It is not an analysis by Sting. Sting doesn't return such definite interpretations: " Black is clearly winning: -+ ".

There is a next wonderful position for "IQ" test.
[d]rk1b4/p2p2p1/1P6/2R2P2/8/2K5/8/5B2 w - - best move Rc8+;

Sting was created thanks to the 80 classic items.
Unfortunately, the higher ELO doesn't mean the better "IQ" abilities.
This also applies to AlphaZero.

Sting evaluates this position much worse than some other engines. So badly in fact, that it could deliberately aim to reach this position for black, only to find it is a draw.

I would have thought that's worth knowing about.

Hello Carl,
just to bumped up - is this (above 2r5/6pk/7p/8/8/7P/1rb1RRPK/8 w - - 0 1) a constructed position
or was it reach by playing between Engines?
