DEFINITIONS


   Take & Make: every capture ("take") must be complemented by a further step ("make": not a capture) by the capturing piece, using the movement of the captured unit, otherwise the capture is illegal. Pawns may not end up on their own first rank. Captures on the promotion rank lead to promotions only if the pawn is still on the promotion rank after the "make" part of the move. Promotions at the end of the "make" element are normal.

   Anti Take & Make: every capture ("take") must be complemented by a further step ("make" - not a capture) by the captured piece (Kings excluded), which must move from its square of vanish (according to the wishes of the capturing side in case of options). The capture is forbidden if the captured unit have not possible move. Promotions at the end of the "make" element are normal.

 

IMPORTANT NOTE

 

   Please note that:

   - in WinChloe both conditions are programmed with priority to Anti Take & Make (this mean that when the capture occur the captured piece moves first and after that the capturing see the examples).

   - in Popeye this is in reverse - Take & Make is with priority (the capturing piece moves first and after that the captured).

This is an interesting combination of two closely related fairy conditions. Most of the times, the contradiction between the two solving programs will not influence the soundness of a problem. However, it is possible that some problems will be sound or unsound, according to which program is used (or, in other words, which fairy condition comes first). How will you (as the judge) treat this contradiction? Will you accept as sound a problem that was tested by (at least) one of these programs?

Yes, in some cases both programs give a different result (it can be for a different cases - for example the priority of the fairy condition etc.). So I will accept problems which are C+ from one program (even that the another give another solution). Of course the solution should be logical and not result of some bug for example.

If you found some original idea to present the difference between order of priority between both conditions - yes. But in this case the more correct twins name will be a) T&M>AT&M and b) AT&M>T&M, because the main content will be the priority of the conditions, not the used checking program.
