Click on the table above to view the winning percentage of every flag position from almost 42,500 Gravon Stratego archived game files. I did not include draws in the calculation.
It looks like the best spots to place your Stratego flag are at the bottom center and bottom left. Placing flags in the bottom center allows you to easily defend your flag from both sides. Your high ranking pieces are never too far away to protect your flag.
There seems to be an outlier with a very good winning percentage on the right wing column, 2nd row(position#19). The reason why it was so high(over 63%) was because a very good player was using the same setup and they won a lot!
The inner wing columns and 2 center columns on the 2 top rows are the worst places to put your flag. Your flags are right in those scouting sweet spots. That makes it very hard to hide your flag location. The 4 squares behind the lakes also seem to be bad locations for your flags. Players always try to scout those squares behind the lakes looking for high ranking pieces and the spy. It's probably not a good idea to place your flag there. Use the chart above to help you find the best flag location to optimize your chances of winning your next Stratego game.
Here's all the raw data I calculated for each flag position. Position 0 is the bottom left square. The position numbering moves left to right for each row. Player 1 is a player that starts the game with a flag at that position. Player 2 is a player that moves 2nd with a flag at that position. The totals combine both stats from Player 1 and 2.
