9x9 Is White's invasion justifiable?

[SuprunP]

Hi everyone!

This is another game I've played against my PC (the easiest level possible).
Although I'm pretty sure there isn't much to comment (since all my moves could be labeled as slightly imperfect), I would like to know whether White's invasion at move 20 was in any way prudent or had my opponent been a tad stronger I would have been dead before I could say 'Go'?



Thanks.

A 3-3 invasion lives in a cramped way with only one of your opponents stones at 4-4. (See the Joseki).
Your 3-3 invasion threatens three things

1] To cut the black group
2] to connect underneath the black group
3] to build up support for a 3-3 invasion in the lower right.

Truth is that black has too much thickness around the area. You are relying on blacks poor play to survive here. The ways of making eyes are too limited for survival and blacks weaknesses 1]-3] are easily healed whilst attacking any white intruder..

There are a number of ways for black to get you.. even late on at move 32, J7 by black kills you...

You took advantage of a weaker player ...

Even at move 33, B can kill W. Can you find the move?

37 is also a blunder. Can you find where black should have played instead?

Some advice I read early on that I found very helpful: Don't play AIs that you can beat easily. You just get left away with more bad habits. You'd be better off getting very close wins or losses versus the AI than playing this one which leaves you get away with murder.

Here are my suggestions about moves 33 and 37.

Oh, but I rarely beat this level (never mind 'easily'). However, I'll try and play with a more difficult level.

Hmm, the problem is that subconsciously you'll start copying moves. You don't want to be copying the moves of a really weak AI.

For 37: That's right, can you see what comes next?

For 33: Very good, you found the killing move. However, your suggestion for 35 is bad - W has a better reply than connecting. Can you find it? And where you B play 35 instead?
