In order to retain a secular government, the military has the constitutional right to remove any elected government it deems to be too religious! That's right, a military coup is part of the constitution!
This unique institution has inspired Ataturk Chess.
Overthrowing the government is simply a matter of naming one of your pieces other than a Pawn as your new King; however, you may not overthrow your government when you are in check, and in addition you must rotate the title.
Even a Bishop may become King. For the sake of playability this game does not attempt to emulate exactly the relevant provisions of the Turkish constitution.
Suppose that White, on the first move, names her Queen as her new royal piece. (This is not a good move, but is chosen to create the desired example position.) The short notation for this will be 1. Qd1++, and the long notation 1. Qd1++(Ke1--).
Now the game proceeds 1...f6 2. e4 g5; whether or not these are good moves is left to the discretion of the reader.
In this position, Qd1-h5 is legal but it is obviously neither check nor checkmate because, although it is a glorious thing, I ween, to be a right-down regular royal Queen, the square g6 is attacked and so the Royal Queen cannot reach e8.
After 3. a3 h6 4. Qd1-h5, is it check? No, because the Royal Queen cannot cross the attacked square at f7.
Can Black play Ke8-f7? No, because f7 is attacked by the royal Queen before the move, even though the Kf7 would not be attacked after the move. Notice that this rule for the behavior of royal pieces means that when an undefended non-royal Bishop gives check at a distance to a royal Bishop, the royal Bishop cannot capture it.
Continuing with 4...a6 5. Bc4, the move Bc4-f7 would in fact be checkmate: Ke8xf7 would be illegal because the royal Q at h5 defends f7.
Better than 5. Bc4 would be 5. Ra1++, which is checkmate because the Qh5 is no longer royal.
Because this change costs a tempo and also restricts your choice of future changes, it is not something to be done lightly.

With three minor pieces (and no King) versus the royal Queen, confinement is easy but checkmate is impossible.
King and two Bishops have a more interesting time against the royal Chancellor, but even when one of the Bishops is made royal there is no way to confine and checkmate the royal Chancellor. The reader should examine this endgame, as it is interesting.
Therefore it seems that the Chancellor should not be used in Ataturk Chess.

With Black to play, the shortest win is 1...Bd1 2. Ng5 Be2 3. Bc2 Bf1 4. Bd1 Bg2 5. Be2 Bh1 6. Bf3 mate.
Before trying a game, one should study whether it is possible to checkmate a royal HFD or a royal Cardinal with a reasonable amount of material; and if not, try another different army instead!
In Ataturk Momentum Chess, pieces that are in motion (by momentum) should not be allowed to become royal; and when you overthrow the government, the moving pieces still move.
Other restrictions on eligibility include Ataturk Alice, new royal must be on same board; Ataturk Colorboundmost, must be same color; Ataturk Archoniclastic, must be same color square (same augmentation state).
The important rule that "you may not overthrow your government when you are in check" means that many sacrificial mating attacks will still work. Without this rule, the midgames would be dull.
We all would like our names to be remembered after we're gone, but being remembered in this way, it seems to me, ain't worth, well, you know.
The game of Warm Spit Chess is based on the vice presidency. Each player always has two royal pieces; the King is always the King, but the Vice-King can be changed according to the rules of Ataturk Chess.
At the start of the game, your Queen is your viceregal piece, and you will wish to change that as soon as convenient.
