International draughts (also called international checkers or Polish draughts) is a strategy board game for two players, one of the variants of draughts. The gameboard comprises 1010 squares in alternating dark and light colours, of which only the 50 dark squares are used. Each player has 20 pieces, light for one player and dark for the other, at opposite sides of the board. In conventional diagrams, the board is displayed with the light pieces at the bottom; in this orientation, the lower-left corner square must be dark.

According to draughts historian Arie van der Stoep, the 100 square draughts board came into use in the Netherlands between 1550 and 1600, and the number of pieces was extended to 2x20 between 1650 and 1700. The name "Polish draughts" was following a Dutch convention of the time that "unnatural" ideas were considered "Polish".[1]
The general rule is that all moves and captures are made diagonally. All references to squares refer to the dark squares only. The main differences from English draughts are: the size of the board (1010), pieces can also capture backward (not only forward), the long-range moving and capturing capability of kings known as flying, and the requirement that the maximum number of men be captured whenever a player has capturing options.
The first world championship was held in international draughts in 1894. It was won by Frenchman Isidore Weiss, who held the title for eighteen years with seven world championship titles. Then, for nearly sixty years, the title was held by representatives from either France or the Netherlands, including Herman Hoogland, Stanislas Bizot, Marius Fabre, Ben Springer, Maurice Raichenbach, Pierre Ghestem, and Piet Roozenburg. In 1956, the hegemony of the French and the Dutch was broken: the champion was Canadian Marcel Deslauriers. In 1958, the USSR's Iser Kuperman became the world champion, beginning the era of Soviet domination in international draughts, a feat which would mirror their domination at chess around this time.
Computer draughts programs have been improving every year. First draughts programs were written in the mid-1970s.[7] The first computer draughts tournament took place in 1987.[8] In 1993, computer draughts program Truus ranked about 40th in the world.[9] In 2003 computer draughts program Buggy beat world number 8 Samb.[10] In 2005, the 10-time world champion and 2005 World champion, Alexei Chizhov, commented that he could not beat the computer, but he also would not lose to the computer.[11] In 2010, the 9 piece endgame database was built.[12]
In the era of graphically advanced computer games with different characters and complex plots, board games remain popular. Isn't it surprising that games like draughts are still a bestseller? People not only buy traditional board games but also search websites where they could play against a virtual opponent and download apps on their phones.
If you think about it thouroughly - this is not a coincidence. Draughts is the game that develops logical thinking and has clear rules. Many of us have very positive associations with childhood when playing draughts or checkers we spent time with our family and friends - parents, grandparents or siblings.
What all variants of draughts have in common is the board - similar to the chessboard. Also at the beginning of the game, each player has the same number of pieces.In most variants, players place their pieces and play the game using black fields, although there are exceptions to this rule. This also results in the configuration of the board - usually the first field on the left side of each player is a dark one.
However, everyone who begins their adventure with draughts should remember that the rules followed by people in different countries are not the same. A Spaniard likes to play according to his rules, but most likely a Brazilian or an American will choose different ones. If, in addition to the general rules, you are also looking for more detailed information about game variants, you've reached the right place Check Variety of draughts - did you know that draughts game rules may differ?
Who starts the game? White pieces but...The first move belongs to the player using white pieces. Players take turns every single move and the player is permitted to move only his own pieces. In general, pieces can be moved diagonally, forward and be placed on the empty field in the next row. Still, there are exceptions to this rule, e.g. Turkish draughts.
King (also named a queen) is a special piece, which can move differently to all the other pieces - and anyone who has ever tried to play draughts, knows how important it is to get a king, as well as how the king can help to win quickly. But none of the pieces has these exceptional privileges at the beginning of the game. It takes a lot of effort to make a piece to become a king - your piece needs to walk through the entire board, reach the promotion line (the most distant row on the opponent's side) and stop on it.
Unlike other pieces, a king can move forwards as well as backwards. In most variants of draughts, the king moves diagonally, provided that your own pieces are not blocking the king's movements and at the same time that the king will not be blocked by your opponent's pieces (placed one behind another). King is allowed to end diagonal movement on any, even the most distant field. The exception to this rule is English draughts and American checkers - a king can only move one field forwards or backwards.
Plant your dragon fruit with some landscaping support (like a trellis) in a sunny but not overly exposed area. A moderate amount of sunlight will produce healthy, large fruits, but too much sun may burn (insolate) the stem. Dragon fruits are typically harvested in midsummer to mid-fall, about 30 days after flowers have bloomed.
The "main loop" (make_dragons(), value_moves.c, move_reasons.c) has quite a lot of heuristics, which work good for a lot ofcases, but often very bad for others. I think there are variousreasons why tuning the main loop is not as attractive: If you do a 5% reading speedup, you know you have done s.th. useful. If you change some of the top level heuristics, it will improveplay in some situations, but it will break other cases. So you never can be sure you have really improved the program. Also,if you assume that the rest of the engine is changing, thanany change at the top level might become nonsense after awhile, whereas an improvement of a "local expert" will notcease to be useful.
It is interesting that "eye", "snake", "dragon", "unsettledness" etc, do not appear in the word list. Is this because they are intuitive, common concepts (i.e. there is no single word to describe them,) or because they are really less important ideas? 2ff7e9595c
