Now IGM Petko Petkov preparing the article "The Chameleons" where he will present a lot of facts, history, theory, examples etc. for different types Chameleon pieces and Chameleon chess. It will be published in KoBulChess.com soon.

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.

Oh, I see.. Are these several tens(!!) of Chameleon pieces at WinChloe (except standard type, marine and chinese) - Free Chameleons then? I believe :) Thanks!

Marine Chameleon: What is their change sequence. I dont see the Marine queen in that list ?
+1 #6 dkostadinov 2012-09-11 00:38
Ram, the sequence is Marine Knight - Marine Bishop (Nereid) - Marine Rook (Triton) - Marine Queen (Siren) - Marine Knight ...
+3 #7 R. Ganapathi 2012-10-26 05:35
In Type B, standard Chameleons also can figure, I presume
+1 #8 Diyan Kostadinov 2012-10-26 12:19
Dear Ganapathi, yes - standart Chameleons also can be included in the problems of section B in combination with another type Chameleons.
+1 #9 R. Ganapathi 2012-11-03 04:43
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.
0 #10 Diyan Kostadinov 2012-11-03 17:04
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.

Petko was twenty years old when inventing Chameleon Piece!
