Do you know the game named "baduk"? There are 19 crosses in ON the board. The width and length of the board is usually as large as that of a chair. The rules of the game are as follows: One player takes black, the opponent takes white. The player who takes black puts a stone in any point of a grid of 19 vertical lines and 19 horizontal lines. The opponent who takes white puts a stone in any empty point. Likewise, two people put the stones by turns. They make their own "houses" figuratively, which are surrounded and protected by their opponent with stones on the board. After the game IS finished, the winner is the player who has more houses. While they are making houses, attacks and defenses happen. In this situation, it can be compared to a battle or war. Nowadays, I can play internet baduk games with USING MY desktop PC in my AT home. Each player has his or her own ID and each player can not ony play games but olso ALSO maintain his or her game records with this ID.
