I don't think so. The LCT test from Frederic Louguet was great when it was
published, and it gave very good results at this time (in 1995).

But if I wanted to, Tiger could easily get 200 more ELO points on this test
suite just by changing 2 lines of code.

The "combinational" part of it is only about mate combinations. Just extending
more on checks and mate threats does the trick.

The LCT is unfortunately not a good test anymore... If you don't want to be
completely off, you'd better not trust it.
