Hi everyone!
Would you be so kind to comment on the following game which I played against the most difficult level of my PC programme?
Thanks.

Overall, you played a good game. You had just a few inaccuracies, but no serious mistakes.
It was still possible to win it up to the last 3 moves. ( Look at the variation on move 29 )

( The long sequences that I show in the middle game were chosen rather quickly, and may not be best. The are just examples of how play might proceed )

When two lone stones are touching, whoever gets the next move in the area has a huge 2-stones-to-1 advantage. Therefore, when your opponent touches your stone, like on move 3, you should usually respond with an extend or a hane. Because you didn't, your opponent got an advantage (and actually was able to capture the stone you placed on move 4 as well), and after that it was difficult to catch up due to the small board size. You actually did have an opportunity to though: at move 20, it's not necessary to defend the bottom, so you can play the big endgame on the left side.
P.S. Joaz, you reviewed the computer's play

I thought the computer needed some help.
