Circe: Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.
Madrasi: Units, other than Kings, are paralysed when they attack each other. Paralysed units cannot move, capture or give check, their only power being that of causing paralysis.
Take & Make: Having captured, a unit must immediately, as part of its move, play a non-capturing move in imitation of the captured unit from the capture-square. If no such move is available, the capture is illegal. Promotion by capture occurs only when a pawn arrives on the promotion rank as the result of a take&make move. Checks are as in normal chess: after the notional capture of the checked K, the checking unit does not move away from the King’s square.

Features:
- On the first move, black gives check to wK which is countered by a paralyzing move to checking piece by white. This white piece helps bK to reach the mating square by T&M which is prospectively controlled by the reappearing white piece due to Circe. However, the first black move is an anticipatory paralyzing move to neutralize this control. Finally white captures the paralyzed black piece releasing the paralysis of mating piece and blocking the line of control of black.
- All moves are T&M.
- Meredith Setting.

Due to take and make, the mating pieces are immune from capture! Hence the shut off from paralysing defence is needed! Very interesting effect. Bala demonstrated a similar effect in Superguards also (see his prize winner).
The composition has quite a long history: this version is the 20th. The most difficult part, after reaching to a setting displaying certain unity between the phases, was to ensure the Madrasi effects are not paling compared to the more visible Circe and Take & Make effects. It seems quite hard to achieve the right balance in compositions featuring three (or more!) fairy conditions.
A matter of definition: Is it in the second solution checkmate? After 3.Kxd1 white Queen is captured on its own Circe-square, so should be removed.
That’s a very good question! Please check the official Take&Make definition here:
http://www.dieschwalbe.de/schwalbe229.htm#tnm
The relevant paragraph is the following:
3) In the combination take&make-Circe, a Circe rebirth takes place only after the complete take&make move, not immediately after its “take” part.
Now it’s clear. Thank you!
It still depends of the “Circe” definition then, imo.
Eg http://www.janko.at/Retros/Glossary/Circe.htm
“When the rebirth square is not empty after the capture, there is no rebirth …”
Note: “after the capture”, not “after the complete move”
Don’t get me wrong, you are correct, of course, my point is that T&M is not sufficiently well defined, to say the least.
Also mentioning that combination with Circe should be treated in a specific way implies that combination with other conditions should be treated … exactly how? In “default” way? 🙂
That’s again a very good question! 🙂
One possibility I would suggest is to consider each specific case independently and properly name each condition accordingly.
For instance, when the rebirth occurs instantly after the capture (not after the full move of the capturing piece), then we could call this particular condition as Immediate Circe.
The second solution of 1156 won’t work with Immediate Circe, as Laco rightly observed, but will still work with [Delayed] Circe.
This approach has several advantages:
a) Would also leave more paths to be explored by the composers’ creativity instead of imposing an official dogmatic rule.
b) Will help the software programmers to eventually get more uniformity in applying the conventions of fairy conditions.
c) Accepts “versioned” fairy conditions (e.g. Madrasi, AntiCirce, Single Box, Isardam, Take&Make …) by default and not by exception.
Sorry for the digression!
hmm… what happens in combination with anti-circe. Does the make move happen from the rebirth square? If make move happens from capture square only is the anti-circe rebirth ignored?
The sequence of the take-rebirth-make it more logical than take-make-rebirth. However, both are useful and the second of them does not deny the use of Anticirce because the move as a whole is impossible if the rebirth square occupied.
From my point of view, take-make-rebirth is more logical, because I feel take-make as move effect, and rebirth as post move effect. But this cannot be confirmed by anything more than feeling.
In combination with anti-circe, it seems to me, that take-rebirth-make is the only sequence applicable.
It depends on whether the rebirth square is chosen by take or make part of move. Example: wBe5xRd4 -> Be4. Which rebirth square would be correct: a8 or h8?
Wrong rebirth squares for wB. Of course – c1 or f1.
T&M is so deeply akin to AntiCirce that forging the alloy of these two conditions looks as enforcing a nonsense.
You are right Nikola! Combining T&M and anti-circe indeed results in absurd results.
The whole point of a new condition is that it’s the INVENTOR who creates the NEW logic of the new system and defines it by rules.
The intrinsic self-consistency of that logic reveals the specific nature of a condition.
A different logic would make a different fairy condition. We might discuss the IMPLICATIONS of the INVENTOR’S logic but it’s absurd to discuss the CLEAR meaning of an EXPLICIT rule.
The specific nature (self-consistent intrinsic logic) of T&M could be explored through some EXPLICIT explanations:
– capture is impossible if the “make-part” is impossible
This indicates that a COMPLETE T&M movement is considered BEFORE a “capture” can have a MEANING.
– NO promotion happens between the “take” and “make” parts of the move
Again the completeness of a movement comes first.
– Circe-rebirth comes AFTER the completed movement of the capturing piece
The mentioned Circe rule:
-“When the rebirth square is not empty after the capture, there is no rebirth …”-
says AFTER and not DURING the capture.
And the capture of some piece is the result of a move made by another piece.
The relation between the capturing/captured piece resembles the relation of Locust/hurdle.
The rebirth happens only AFTER the Locust’s movement is completed.
The “captured piece” serves first as a specific hurdle to the “capturing piece”, determining the complete “make” part and only then is removed.
The logic of a “hurdle” might apply to a hypothetical condition “MEET&MAKE” where
– captures are orthodox but a non-capturing move might use an opponent’s piece as a specific “MEET&MAKE” hurdle, e.g.:
wBa1,bSb2; possible moves by wB
1.Bxb2 capturing bS
1.Ba4,Bc4,Bd3,Bd1 without capturing bS
