HW10: Fixed some major (stupid) typo

1..... Found some stupid typo, guess that's why the AI plays so dumb...
(Now is better, even with less response time :) )
2. Sorry for so many commits... That should be the last one.
3. For a more challenged one, V3-1 has 2s response time and should be
"smarter...". (At least I lost in the first match.....)
