Some interesting Grand Dice Chess problems

 I will post some interesting Grand Dice Chess problems here.

Since we are not dealing with regular chess, where engines are able to evaluate and fully calculate the situation on the board, there will be practically no solutions to these problems.

In all Grand Dice Chess puzzles and problems, one should first of all be guided by intuition and imagination.

1. Black to move 1-1-1-5

2. White to move 1-2-3-5

3. Black to move 1-1-5-5

4. Black to move 1-2-3-3

5. Black to move 1-4-5-5

6. White to play 1-3-3-5. Can you capture Black's King on e12?

The First Experimental Grand Dice Chess Tournament has started

Finally the First Experimental Grand Dice Chess Tournament has started. 10 people from six countries of the world take part in this event.

I want to express my deep gratitude to all those who took part in this event.

Dice have a few interesting properties that we need to know about.

First, the probability of dropping any of the faces is the same. Thus, if you want to know the average dice roll, sum the values ​​of all the faces and divide that sum by the number of faces. The average roll of a standard six-sided die is 1+2+3+4+5+6 = 21 divided by the number of faces (6) and we get an average of 21/6 = 3.5. This is a special case because we assume that all outcomes are equally likely.

The indication of each side of the dice is equally probable. This does not depend on how many dice you roll. Each roll of the die is independent, which means that previous rolls do not affect the results of subsequent rolls. With enough trials, you are bound to notice a "range" of numbers, such as mostly larger or smaller numbers, or other features but this does not mean that the dice are "hot" or "cold."

If you roll a standard six-sided die and the number 6 comes up twice in a row, the probability that the next roll will result in a 6 is also 1/6. The probability is not increased by the fact that this dice is “warmed up”. The probability does not decrease, because the number 6 has already been twice in a row, which means that now this dice will show us another face. (Of course, if you roll a die twenty times and the number 6 comes up every time, the chance of a 6 coming up the twenty-first time is pretty high...because that might mean you have the wrong die!).

If you roll a single die, the probability of each of the faces coming up is the same. This means that if you roll a lot of dice, over time, each face will come up about the same number of times. The more dice you roll, the more the total result will approach the average. It's not because the rolled number "causes" another number to roll that hasn't yet come up. Because a small streak of rolling the number 6 doesn't end up being a big deal if you roll the dice ten thousand more times and it's mostly the average...Not because the previous rolls affect the dice (seriously, the dice is made of plastic, it doesn't have the brains to think "oh, it's been a long time since a 2 came up"), but because that's what usually happens with a lot of rolls of the dice. A small series of repeating numbers will be almost invisible in a large number of results.

Keep in mind that the fewer dice used in the game, the higher the randomness, and the more dice, the lower the randomness.

Why Grand Dice Chess?

Many people forget that chess, as we know it now, evolved precisely from chess with dice. We are just returning to the roots, returning to chess the concept of a GAME, not a science, where for every mistake you get an 'F' from 'professors' who love to teach others so much.

Chess in its modern form is a sport of chess engines, there is nothing human left there. Emotions are punished. Improvisation is punishable. Strict logic is a lifeless landscape of the human mind.

At Dice chess and at Grand Dice Chess in particular, we are freelance artists creating unique masterpieces on the chessboard.

Nothing fetters us, we have no chains of stiff theories and memorized schemes. We create with the help of intuition and imagination, guided only by dice, which in essence are generators of random events.

Each game is a work of art and each final position of a chess battle is the result of the work of two chess artists.

First Grand Dice Chess Tournament online

Grand Dice Chess

The Rules

The game uses a 12x12 board.

Each player has:

4 Kings

24 Pawns

8 Knights

8 Bishops

8 Rooks

4 Queens

White and black occupy the 1st-6th and 7th-12th ranks, respectively, as shown in the diagram.

White starts the game first.

The game uses four dice.

Opponents make moves alternately, throwing 4 dice. The piece to move is determined by a die:

1 = pawn, 2 = knight, 3 = bishop, 4 = rook, 5 = queen and 6 = king.

The player makes four moves at the same time based on the indications of the dice and has the right to refuse any move that does not suit him, unless it is a pawn move. Exactly! Unlike in regular dice chess it's allowable to pass moves. And this rule was already applied about a thousand years ago in old variant of Shatranj (Shatranj al-Mustatîla or Oblong Chess), the Arabic pre-decessor of modern chess. However it's not allowed to pass on pawn-moves, except when they are blocked.

Chess pieces move across the board as they do in ordinary chess - according to the standard rules of move and capture.

The only minor exception is for a pawn that is not allowed to move forward two squares from its starting position.

Upon reaching the last rank, the pawn can be promoted to any piece except the king and itself.

There is no castling, check and checkmate in the game.

The goal of the game is to capture four enemy kings.
