First check the connection, then check the short point
This site uses a six-piece board with 21 intersections, with six black and six white pieces on the board, and Black goes first. Each turn, only one piece of your own moves is moved, following a line to an adjacent empty point. You cannot jump across a piece, and points that are close but not connected on the screen cannot be reached directly.
After selecting the pieces, first confirm that the destination points are adjacent along the line and have no pieces, then calculate the liberties on both sides after the move.
What is liberties in a "set of chess"?
Pieces of the same color are directly adjacent by a connected line, which means they belong to the same group; This group of pieces touches along the connecting lineDifferent blank pointsis its liberties. Even if two pieces in the same empty point are next to each other in the group, it counts as one liberties.
For example, if a black piece only touches one empty point, if White legally moves to that point, Black loses the last liberties of the entire black group and is taken away together. Capture does not simply remove the piece that was directly touched by the moving stone.
Conduct three check-ups before leaving
- Check in place.After removing your own piece, the original point becomes empty; This empty point may allow the adjacent set to gain another liberties.
- Check the landing point.After the piece is played, if the opponent's group has no liberties, the program will first capture that group's pieces; At the same time, it may take more than one piece.
- Check yourself.After capturing complete, your new set must still have liberties. Moves without liberties and without mentioning the opponent's pieces are illegal.
Practical order: First, see if you can capture, then see if the opponent can seal your last liberties in the next move.
How to end a round
Reduce the opponent's move to only two pieces, or make the opponent's turn to move without a valid move, win. If the same position and the player's turn move accumulate to three times, or if there is no capture in eighty moves in a row, the program judges it a draw. Repeatedly moving in the same position may not be advantageous, especially when it comes to repeated positions.
The game allows you to switch between playing Black or White and four computer difficulty levels. Beginners can start with Black and practice the order of "selecting pieces, checking connections, counting liberties" on easy difficulty.
