Thanks for the dedication Sébastien! The twinning is very good. You’ve done well to find a position that is C+ with both WinChloe and Popeye.

I am very sure you can do better than this!

The pieces and condition are identical to Geoff’s problem. And the two mates are almost the same. So I do not know why you made it!

[The trouble with having to mate with two neutral pieces is that there has to be either a double-check or the checking piece must be blocked. Both problems show each of these ways in almost an identical configuration. All this is not so interesting. Solvers know what has to be done].

[I think it is preferable instead of two neutral pieces to have two white pieces and one black for interaction purposes].

It is not good that you place the bK in the centre of the board and then have 3 out of 7 half-moves in each part spent marching the K to the side of the board – playing no part in ChameleonCirce – except for one capture.

The Chameleon condition is most amenable to the Royal piece concept. This enables ALL pieces to partake in Chameleon moves.

Also with ChameleonChess and ChameleonCirce it can be interesting having AntiAndernach as well. [I know though that having 3 conditions is a PH weakness].

I do not know how interested you are in the ChameleonChess and ChameleonCirce combination.

I append below 4 problems that may give you some ideas. Except for the first of them they all go along with having only Ss as per Geoff’s problem.

[I could probably fine-tune these problems if I spent more time on them].

Dear Peter,

Geoff Foster is a good friend : he helped me in the redaction of one of my article about neutral Pawns, and I like some of his ideas. That is why, I wanted to give him a dedicated problem !

If you want to judge it technically, I must admit it is not the most interesting I composed recently

…BUT it is in two solutions with mutual capture b4d5 and

I have to say it is not the case of a lot of your problems in monosolution with 4 or 5 fairy conditions we can see in Winchloe database and cooked by Winchloe program !!
My advise for you Peter is to check your problems with Winchloe !

I have not the slightest interest in checking my problems with WinChloe.

And I cannot see how it can be thought that to make a problem that is C+ with both Popeye and WinChloe is in any way an achievement.

Would love your thoughts, please comment.x
