You say "white has excellent winning chances".
Why?
Isn't the position a draw?
Code:
35/58   33:40    5.446.024k   2.695k   +0,18   Ra1-a8+ Kg8-f7 Ra8-h8 Kf7-e6

So you come up with a statement and make conclusions.
What if your statement is wrong?
Please refrain from giving other people a D.
Kind regards
Bernhard


Man, I do not know if the position is possibly a draw in one of its endless ramifications. I said that white has good winning chances, although lagging behind in material. This illustrates the point that a pair of knights are due a redundancy penalty, what was my primary intention. It was intended as an illustration, so that people say, well, there might be something true about it.

I wonder which engine you have used (you did not mention it), but, in case you have used SF, you should know that this is one of the engines you should not use here, as as of late SF underestimates rooks in endgames and generally overestimates knights.

You might want to look at Houdini, Gull, etc., for this specific ending.

But, even if the true score is only 18cps white edge, this also supports my point, as in terms of material black leads by some 50cps, so you should explain where those 70cps difference in performance come from.
