Marinating

I propose to add the so-called Pickling to the list of games. It is a simple and interesting game, where everything is like chess except that there is no capturing move, i.e. you cannot directly "take down" the opponent's piece. A piece can be taken down only if it has no moves and at least one of these potential moves is blocked by the opponent's piece (otherwise, most of the pieces would be "pickled" in the initial position, since you can only move with knights). You can also take down 2 pieces at once, if with one and the same move the last move opportunity is taken away from 2 opponent pieces at once. The only more difficult part is "pickling" the pawn. For this, it is not enough to block the square directly in front of the pawn (i.e. the path of movement), it is also necessary that there are pieces on both sides of the diagonal in front of the pawn (e.g. if the white pawn is on e4, in addition to the square on e5, the squares f5 and d5 must also be occupied by pieces (and at least one of them must be occupied by a black piece). The game is won by the one who checks the opponent's king, i.e. provides fire in such a way that the king cannot hide from the fire (as is known, you cannot capture the piece that provides fire, but it is possible to "pickle" this piece).

Pickling is a good game, it would be nice if you could play it online somewhere

1) Is capturing such a piece mandatory or optional? That is, does the blocked piece have to automatically disappear from the board? 2) Does this game have an English name? 3) Does castling happen according to the rules of regular chess? 4) I guess the En-Passant move doesn't exist here? 5) Does giving fire to the king also happen according to the rules of regular chess?

1) It is possible to play with different rules, but in general, capturing is still mandatory. This also seems easier to do here, because otherwise the player with the capturing option must be given a few seconds after making a move to, for example, click on the piece to be captured. 2) I don't know the English name, other pickling enthusiasts like gertel and Valerixxx, do you? 3) Castling is done as in regular chess. 4) En-passant really doesn't exist, as does any other capturing move in regular chess. 5) Checkmate is done as in regular chess and also on the same principle, i.e. if the king is under fire and it is not possible to free him from the fire - this release can be done by moving the king, by bringing one of your pieces in between, or by pickling the piece that gives fire.

was not checkmate! Black can pickle the white rook that is giving fire with the flag (by moving Flag b6-c7) But it's very good that you reported the problems immediately, be sure to do so in case of any doubts.

Capturing is not mandatory in marinating. This is a pretty important rule. There was just one case where I thought I had checked, but the program automatically took a pawn from the opponent's king (which I didn't want to do at all!) and there was no checkmate. Maybe this can be fixed in the program.

yes RJF is right. and in my opinion it could be that you have to remove the button yourself and if you don't see it then it won't go away

Fantunes, what do you think about this voluntary removal? And at the moment I can't imagine how this voluntary removal could be realized.

I initially proposed this mandatory removal primarily because of the simpler implementation (see the first post). The game has generally been played without this obligation at the table. The implementation could be done, for example, something like this: the program should identify moves where it is possible to remove the opponent's piece, and in this case the opponent's time would not start immediately, but there would be 1-2 seconds to click on the piece to be removed. Only then would the opponent's time start running.
