I'm sorry but this is the responsability of the testers.
It is common knowledge of programmers that 12Kb of hash tables is inferior to
192Mb.
So if the tester wants to use 12Kb of hash table, should the program:
1) use 12Kb?
2) refuse to run?
3) use 192Mb no matter what?
I can already hear the complains if I program 2 or 3...
There are many ways to set up a program incorrectly. The programs generally are
able to catch a number of common cases, but not all of them.
And some of the incorrect setups for long time controls can be absolutely
correct in some other circumstances (tests on positions only, bullet games...).
What is the SSDF testing? The real strength of chess programs or their ability
to recover from bad setups?
