EET 67 is buggy

[fen]8/1p2R3/8/p5P1/3k4/P2p2K1/1P6/5r2 w - - 0 1[/fen]

Another busted test position. Listed solution 1. Kg2! All moves lose. But this is quite difficult and takes time.

What is your point?

I use 7-pieces syzygy tablebases since many years and I have a very slow pc and BanksiaGUI.
It takes 115 ms to find Kg2 -4.74 and Stockfish never changed it later.

The point is that this is a test position in a very well-respected endgame test suite. So it is clearly good to know that it has been refuted.

Yes,

60.Rd7 -18.40/29
60.Rb7 -18.55/29

And after 60.Kg2 is ...Rf8 winning, 61.Rd7 Ke3 -19.15/32

You are right, this test position is "cooked".
However, this whole test suite is out of date anyway, because I made this suite 10 years ago.
In the meantime I have taken the 100 positions off the net.

Well, for mediocre engines like Myrddin, it's still very useful. So thank you very much for creating it!
