I find I can win virtually every time on the website, except when I make a clearly unwise blunder. (Probably having played a lot of Hex doesn't hurt any.) The mathematical question on an infinite board seems to be * From which starting positions (darkened cells and position of the cat) can the cat be captured? * In particular: Can the cat be captured even if no cells are darkened? The game is similar in spirit to Conway's Angel & Devil game. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
