Online chess often does not use the touch rule, letting players "pick up" a piece and then bring it back to the original square before selecting a different piece, and also allowing players to premove pieces while waiting for the opponent to move. A few sites such as the USCF and FIDE online chess websites enforce touch-move by disallowing any ...
In chess, a trap is a move which tempts the opponent to play a bad move. [1] Traps are common in all phases of the game; in the opening, some traps have occurred often enough that they have acquired names. [citation needed] If the opponent sees through the trap, it can backfire. [1]
However, using an ordinary tap or die to clean threads generally removes some material, which results in looser, weaker threads. Because of this, machinists generally clean threads with special taps and dies—called chasers—made for that purpose. Chasers are made of softer materials and don't cut new threads.
The players alternate rolling the dice and, if possible, moving. On each die, the 1 represents a pawn, 2 a knight, 3 a bishop, 4 a rook, 5 a queen, and 6 a king.The player may move either of the pieces indicated on the two dice.
