I prefer Robin's because it's a realistic position. Razz Wink

I agree. If you're going to have a test position, it should be something that might realistically be seen in actual game play.

This position does not seem to meet several criteria:
1) Some programs select Kxh2 even without tablebases. For example Fritz selects Kxh2 for the first few seconds before switching away.
2) There is not only one winning move. In fact quite the opposite: every move wins.
3) It is not clear that Kxh2 leads to the fastest win. It does lead most quickly to a known won tablebase position, but that does not mean it wins the fastest. Therefore saying Kxh2 is the best move is uncertain.


OK, apparently everyone is clever enough to point out flaws in my test position. Very Happy Surprise, I am aware that it is unrealistic position and a bad test. I would much rather see better positions myself! I added my position (however bad it is) just as a motivating example, hoping that someone can do better. Smile

Robin's position is very close to be a perfect test. My position is very far, and is only listed as possibly useful. There was no perfect test position proposed yet. This all you can see in my post here where I collect all submitted positions so far and my comments about each.

To really show your genius, please think up a position that will meet the criteria and become first entry in the EGTB test suite. I will be really happy and impressed to see a perfect test position! Thanks! Very Happy

Best wishes,
Kirill
