Thanks for the invitation! I'll participate for sure! I like your blue-colored chameleon picture - my favorite color :)
But seriously: I'd appreciate a lot the article you've written about. Until now I've used only a standard Chameleon type of S-B-R-Q-S, the idea of Marine & Chinese is clear.. But what is the behaviour of Free Chameleon??

I'll add your announcement at my site as well. /julia.

Hi Julia, you can find more differen types of Chameleons (Free Chameleon) in WinChloe. For example the pieces changing in the following sequence: B-S-B..., or Q-R-B-S-Q..., R-S-R..., R-S-P-B etc.

In Type B, standard Chameleons also can figure, I presume

What is a Marine Knight and how is it indicated in Popeye?I find Popeye not responding to Chameleon Chinese pieces nor to Chameleon Marine pieces. Is it so? But Standard Chameleon condition works.

I think that Chinese pieces and Marine pieces Chameleons are not included into Popeye yet (or somebody have another information about that?). You can check problems of this kind with WinChloe.
