WTF? black could have mated easily in 2 at move 23 by doing Qf2 and then Qg2# or Qh2# after Kh1!

OR

at move 27. ...Qf2#

As he didn;t do that, well after the exchanges...he should've won anyway with material advantage!

What's the rating of the rating of the CPU? (assuming it has one)

Computer rated 1600. I am a 1150 player just starting to get serious about the game, hence the request for analysis by those who have a much better understanding. Will help me as I go back over the game and try to improve myself. Thanks for the feedback. :)
