when a figure is taken, the King of the side of the said figure acquires his moving way.
When a pawn is captured, said King becomes normal again.
In Eiffel, the units are paralysed according to the P-N-B-R-Q-P cycle.
Important precision
the Winchloé rules apply here regarding the mixture of the 2 conditions: .
If a King is transformed into another piece, he has the power to paralyse according to the Eiffel rules, but not to be paralysed.

The path between the start square and the sautoir must be free, as well as between the sautoir and the finish square,.
which can either be free or occupied by an opponent's piece.
the Lion-Bishop moves on the lines of the Bishop, the Lion-Rook, the Rook and the Lion himself, those of the Queen
a captured unit is reborn at the same place after capturing unit leave the square.
In case of successive captures on the same square, only the last captured unit is reborn.

a unit acquires the moving way of the friendly unit located "under" it.
The White King is not in check, because Nb1 has "under" him a pawn and thus plays like a pawn (in this case, he is paralysed).
Note that the pf3 behaves like a Bishop because of the Bf2

the captured unit remains suspended on the capture square, and after another unit (the "parrain") has played,
moves equipollent if possible
In consequent, the legality of each position must be considered in its own right.
(independently of other moves)
{ }
1.Bd4-a1 {!! This position, White to move, must be legal.
Obviously, the last move was ...Kb2xXb1, but then the last moves must have been ...Na3xBb1, Rc1xNb1+ (+bBa1) ...Kb2xRb1..
So there is a white rook "under the belly" of the Black King.}
2.Ba1-d4[+wRe4] {The "parrain" allows the rebirth of a wRe4.}
3.Bd4-a1 ! { Again, this position can only be obtained if the last move was ...Kb2xRb1..
So there is again a wR "under the belly" of the bK and the rest is} 4.Re4-h4[+wRe1] !
{For the third time, the last move must have been ...Kb2xRb1).
D'où} 5.Kd1-d2[+wRb2] #
{the double check was not necessary but the a2 guard was!
"Renaissance" of 3 white Rooks.
Correction and improvement of a 1991 problem.
There should not be many serial problems starting with 1.Bd4-a1, 2 Ba1-d4 and 3 Bd4-a1!
Without the Pc2, the last moves could also have been ...Ka3xBb2, Bc2-b1+ (+wBa1) Kb2xBb1.}
