/ Superply Web Edition
/ Code author: Dennis Shasha, 2002

/ Here is the activity we want. Display a choice of boards.
/ Once a board is chosen, display it with blanks and with the 
/ row and column headers showing.
/ Then put up the header that says: Red (horizontal) moves first.
/ Show a hint card.
/ When a player clicks the first one, see whether the hint matches.
/ If so, then fill that space with color (showing the answer)
/ and see whether that player wins. If correct but player doesn't win
/ then the player goes into addmove mode where there is a contiguity
/ requirement.
/ When a player's move does not satisfy the requirement, then play
/ continues with the other player.
/ Must have the ability to match a hint to a choice.
/
/ New interface: go to attbroker at port 2000 and attman at port 2120 etc.
/ attbroker gives a session id and a port as before, but there can
/ be many sessions on a given port. The session id should be part
/ of the command:
/ each command should have the intended command then colon then a session id,
/ e.g. sendtables:31
/ Guangwei: set the m h to 2120, 2121 etc.
/ Set the m i 1000 higher.
