Ethan,
1) The page will reload when you click on "Enter move", ISTM.
2) Instead of doing alert("yippee"), seems to me you should alert on the results of the ajax call. I don't know how you get at those with jquery, but I imagine that is where you'll find the results of doing var_dump($_POST);
3) Where *are* you expecting the output from var_dump($_POST); to appear, and why?
4) You say the ajax call "works". Well, for some value of "works", perhaps, but you are calling for your own page to be the script to be run, I can't really see the point of that.
5) For a simple but effective ajax example, see http://www.clothears.org.uk.
6) If you're attaching an onclick to each table cell, the onclick handler can write the cell's id into the form, seems to me. Why use ajax for that?
BTW, I'm replying via the list (even though so far this has minimal PHP content) because my mail host at clothears appears to be on earthlink's shitlist.
