Open tria An open tria is a line of three stones that are not bound on either side of the line by an opponent's stones. Open trias are powerful because they threaten to form an open tessera on the next turn if the opponent doesn't respond to block the tria. Open tesseras are the most powerful shape in Pente, short of the eponymous and winning "pente" pattern of five stones in a row. An open tria allows the player who placed them to create initiative for themselves because of how it forces the opponent to move to respond. The ability to form many open trias each turn forces the other player to respond and allows the placing player to form a powerful board presence with many options for attack, while the defending generally has to place stones in many locations all over the board that are disconnected and not immediately helpful for forming pentes and other powerful patterns.
