HIARCS15 Analysis:
White: 2 mistakes and 2 inaccuracies.
Black: 2 mistakes and 5 inaccuracies.
This game was fairly even for both sides until about half way through. See the following position:
Here, White had just played 33.Ra1 and Black has two passed Pawns marching down the board. His Pawn on a3 is the most troublesome. From here Black played 33…Ra5 which is a mistake according to H15. The better move is 33…a2 The plan then is for Black to move it’s Knight and Rook down forcing White to defend and ultimately losing it’s Knight in the process. I don’t think this is necessarily beyond TheKing’s ability to see, but maybe the more selective searching of KingA missed this particular variation?
Looking a few moves on in the following position, White had just played 39.Kb2:
KingN is now in a better position and a pawn up. It also probable Black’s Pawn on a2 will be lost at some point. KingA’s evaluation was -0.7 whilst KingN’s was 1.52 which is the closer value to H15’s 2.18. It’s from this point that KingN’s endgame is better.
Here is another example where KingA’s more selective searching may be the cause of missing nuances of an endgame:
KingN as White had just played 47.c5 Marching towards the queening square. Here, KA played 47…g6!? Now, White can advance his Pawn again! Black should have played 47…Kd7. In this position KingN was searching ahead with 9 brute force and 10 selective moves (09|10) whilst KingA was searching with 02|11, so I think this is where the more brute force option selected by KingN has been more beneficial. But this is just an impression.
Current score 4 – 1 to KingN
It’s looking a little one-sided but things could change.
