Hi Marc, thanks for your reply.
I’ve already solved it, just wanted to try to be more accurate using the image reference, so the rook has 6 (windows? or holes) in a 8 face polygon, so was pretty uneven as you can see in the pictures, so finally I went for the 4 & 4 , so was easier in that way, maybe in a future and more study of Blender allows me to do it in that way.
Here is the post with my final render of the Chess set.
Thanks again and I really appreciate your help.
Cheers!
Pablo
