         If you would like to be provided with a 10x10 board instead of the default 8x8 board, you can add a <code>uses_10x10_board</code> variable to your strategy class.
-        This variable works the same way as the <code>logging</code> variable, in that it must be an attribute of the <code>Strategy</code> class and will default to <code>False</code> if omitted.
+        This will surround the 8x8 board with an additional layer of <code>'?'</code> characters, as shown below.
+        Similar to the <code>logging</code> variable, <code>uses_10x10_board</code> must be an attribute of the <code>Strategy</code> class and will default to <code>False</code> if omitted.
     </p>
     <p>
-        You can also use a similar <code>uses_10x10_moves</code> variable to signify that your submitted <code>best_move.value</code> refers to indices in this 10x10 board.
-        If not used, the server will assume that your <code>best_move.value</code> refers to indices in the default 8x8 board.
+        You can also use the <code>uses_10x10_moves</code> variable to signify that your submitted <code>best_move.value</code> refers to indices in this 10x10 board representation.
+        If not used, the server will assume that your <code>best_move.value</code> refers to indices in the default 8x8 board, irrespective of whether or not <code>uses_10x10_board</code> is enabled.
