In this recent K9 vs G3, at 39.K9 played Re2 instead of Rxd6.What do you think about that move?

With only a very brief 1 - 2 minute look and no engines (or chess board for that matter :) ): 39. Rxd6 Nxe4+? seems to lose Black's b-pawn. 39. Rxd6 Kxd6 40. Nb5+ Kc5 41. Nc3 Kd4 looks a bit unclear to me.

I think we are looking at Komodo 9.25 soon, because Rxd6 seems winning, but what was the score for Re2 from Komodo?

Here the latest Rainbow Serpent, version 034, another TCEC arbiter version for minimal hardware, all versions tested by hand by me :)

Well, going a bit deeper the high eval is a bit unstable or the search from Rainbow Serpent is unstable :) and drops to 0.87 so it's possible Komodo detected a fortress in the search after Rxd6. There is only 5 men tables I believe, or is it different for each stage? This is without tablebases.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

I think we are looking at Komodo 9.25 soon, because Rxd6 seems winning, but what was the score for Re2 from Komodo?

Here is the latest Komodo-9.2 (note that 9.1 is playing in TCEC now) with 16 threads, 3072 MB hash and 5-man tables (as in TCEC).

Thanks for running Komodo 9.2 Louis!


I think my good result may have been the result of search instability after all :oops:, that or the variation with 39.Rxd6 Ng4+ without tablebases is also looking drawish, but version 036 no longer finds it and worse, after the Komodo solution 39. Rxd6 Kxd6 it thinks this is very good for White. This is one of the largest misevaluations of Stockfish I have seen in endgames. But nobody has complained? It is never getting better if nobody signals this because some of the developers are allergic to Stockfish having special rules for the endgame. Syzygy tablebases have to do it then. RS latest version, but I'm betting Stockfish is not better, gets this result without them :(

If 39. Rxd6 Kxd6

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
