The situation is perfectly clear.  You have a design or coding error in
your script.  But it is hard to say what, or where, it is.

If you were to read the newsgroup FAQ, or ECMA 262 edition 5.1, or my
Web site, you might well do better.  Try all three.

BTW, please do not assume that the generality of readers is familiar
with all Americanisms/Canadianisms.  Use the international subset of
English, if you can.



If you want to be sure that the winning move is announced after it is
shown, let the code execution come to a natural end after the winning
move is shown.  Immediately before that end, put

        var Good, Result ;
        // Good = ...
        Result = Good ? 'win' : 'lose'
        setTimeout("alert('" + Result + "')", 1000)

or, better

        function Show() { alert(Result) }
        var Good, Result ;
        // Good = ...
        Result = Good ? 'win' : 'lose'
        setTimeout(Show, 1000)

The 1000 is for initial test; unless redrawing your game is unreasonably
complex, 10 should do.  Therefore, consider 50 or 100.

There may, and probably should, be an explicit Method for redrawing the
screen, and optionally waiting until that is finished..
