I have released an updated version of Cake; 1.89d now finally uses the full pattern-based approach that Ed Gilbert brought to English checkers about 2 years ago. To give an idea on what kind of difference this makes, here's a match result against Cake 1.81, the last published "standard" version of Cake:
Cake 1.89d - Cake 1.81: +55 -0 =233 (1s/move, 8pc databases, modern laptop).
And if you think Cake 1.81 was weak - it was very probably stronger than the last computer checkers world champion (Nemesis) which in turn was certainly stronger than the famous Chinook.

Re: Cake 1.89d
Small correction: the last "traditional" version of Cake was 1.85, and I repeated the match and now it's not quite as bad, but still extremely lopsided:
Cake 1.89d - Cake 1.85: +42 -1 =245 (1s/move, 8pc databases, modern laptop).
Cake 1.89d - Cake 1.85: +42 -1 =245 (1s/move, 8pc databases, modern laptop).

...and for good measure, I recompiled Cake Sans Souci (1.04k) for the current 64-bit platform. Back in 2003 this was probably the strongest checkers engine around.
Cake 1.89d - Cake Sans Souci 1.04k: +73 -0 =215.
Amazing!
