Looking at diagram 5 it should be apparent that if you can force your opponent to take all four corners and edges they are likely to end up with the most discs. Simply inverting the positional values of each square gives a first approximation to a fixed evaluation of the reverse game. Further study shows that while occupying an X-square in the classic game is likely to give away a corner and is therefore usually a bad move, control of both the C-squares and the X-square is required if you are to oblige your opponent to take up the corner. Once a disc has been placed on a C-square it can only be flipped by a move to the corner square. The X-square can be flipped more readily and may be used by your opponent as a stepping stone to a C-square. Likewise taking an early A-square can provide access to C-squares for your opponent so should probably be avoided. At least one A-square will be required to prevent any possibility of your opponent flipping the X-square later in the game however. Compare the south-east & south-west corners of the diagram 8 below. Black will almost certainly have to play to h8 before the game is out, gaining an unwanted corner. However playing b6 will flip the disc on b7 and if white cannot flip b7 again then, depending on the relative mobility during the endgame, there is a possibility that white may have to take the south-west corner before the conclusion of the game.

While acknowledging the limitations of pure positional strategy I would suggest the above static table for consideration as a quick guide to the likely relative value of various squares in Reversed Reversi. In short, C-squares are nearly always useful, whereas those adjacent to them should probably be avoided because they provide access to the C-square.

In Swap2 rule, the first player starts by placing three stones (2 black and 1 white, if black goes first) on the board. The second player then selects one of three options: play black, play white and place one more stone, or place two more stones and let the first player choose the color. This is essentially a slightly more elaborate pie rule.
