@Mr.Wizard - thanks for the pointer, I have somehow missed it.

comment Detecting patterns of black and white stones on a 2D board
I had a hard time choosing between your solution and Mr.Wizard's, but I decided to go with his as it can be better generalized for a 2D (not linear) patterns, which strictly speaking was my original question, even though for my needs linear patterns will probably be enough. I'm still very grateful for you sharing your solution - I think I'm finally starting to appreciate the beauty of Reap and Sow.

@Mr.Wizard - do you know a good place to read more about CellularAutomaton? The built-in documentation is quite sparse - I don't fully understand what each of the different types of rule mean. I have Wolfram's NKS, but I've only read through first couple of chapters - is it described there?

Ok, I fully understood your solution, and it's beautiful. I can see now how I can add diagonal and non-linear patterns, too.

@Pellesatansfant - thanks for the effort, but as the others have pointed out already, your solution is probably not very useful to me, for two reasons: 1) I want a Mathematica solution, and 2) Your solution doesn't really allow to define new patterns easily.

Is there a way to define new patterns easily, similar to my matchPattern below?

Thanks George - and +1 for a nice reversi visual. It looks like what you are suggesting here is somewhat similar to my solution below, but I would need to spend some time to truly understand what you are doing there.

Thanks Mr. Wizard. Although it doesn't fully answer my question, it is very inspirational. I will try to wrap my head around some of the new idioms that you are showing here over the weekend.
