Just my opinion, but I think it's the best way to learn. Go isn't about placing stones to "do something" but about placing stones that do something with respect to stones already on the board.
Playing high handicap games against a much stronger player is how to learn about "keeping stones connected".
Playing low handicap games against a stronger player how to learn without picking up the bad habits of your own level (which would happen when playing opponents of your own level). And with the more open board of a low handicap game, not so terribly different than an even game.

IMO, during your first year of play you should play opponents at least 5 stones stronger than you, if possible. After you have played for three years you should make sure to play some games where you give 5 or more stones, to return the favor.

Thanks for the games
I definitely felt you getting stronger in the course of those three games. Not sure if you noticed it, but I was definitely scrambling desperately in that last game :p
Feel free to ask if you have any questions about the games, and I'll be more than happy to play more games with different handicap patterns if you are interested.

Thank you, at some point I was thinking... hey there is still no two eyes for white... should I try something... and then the fear came back and the answer was : no, to much liberty... I should not be to much agressive...

- Was my playing right to answer
?- white 29 : would E17 be a better reply then my C17
- black 40 : is double turn right in this case ?
- white 161 :is there a better way to replay here

1) As I mentioned in the malkovich log, I think taking the 3-3 point at C3 there was the right response - then it is hard for white to find a reply. There are too many possible variations to list, but the idea is that C3 would deny the white stone at move 21 easy base in corner and also strengthen black's shape in the area. Note that white 19 and 21 are both weak and white can only hope to protect one after black takes C3.
2) I would probably play E17 myself, though I think C17 is also ok. E17 gives white more chances to complicate the game (for example, with a cross-cut at E16 or with a hane at either C16 or E18).
3) I think the double hane is not too bad, though it does give up a lot on the bottom. I think the issue came earlier - instead of R4 you can consider P2 at move 38. The idea is that R6 doesn't really accomplish much if you play R4, but serves a purpose when you play P2. One key idea in Go is to make sure your moves work efficiently with previous stones played.
4) I think S15 is the cleanest way to kill. Then if white R17 (strongest resistance that I can see) black just Q18 and white can't make 2 eyes. The precise sequences might be a bit too complicated for you at this stage, but the local situation is closely tied to an important corner shape. Refer to http://senseis.xmp.net/?LGroup if you are interested. This also is a good demonstration of one (of many) reason that life and death problems are extremely important - all I had to do was to read out that white can't get a better shape than the L-group in the corner if black S15 and stop. It would be considerably more challenging to read the thing from beginning to end without knowing the L-group.

Oh ok, I miss interpreted the malkovich log, and was thinking that you considered C3 for yourself...
so maybe something like that... or
at "a"oca : black 40 : is double turn right in this case ?
illluck : ... I think the issue came earlier - instead of R4 you can consider P2 at move 38.
For sure P2... why didn't I saw that... seems so easy when someone tells you...

I use to read something a about The L-group in the corner, so for now I just know that "it's not that easy".
I'm still working with the basic "one"
That help me with my bottom left group, (even if I missed the seki...)

Oca, I'd say that this is precisely how you could best improve most rapidly. As Ed pointed out, repeated failure to prevent broken shape, and how to maintain connection is the lesson to be learned by playing nine stone games against a strong opponent.
If you can't get enough nine stone games against a human, at your level you could always try using a computer program opponent. The danger of learning bad habits from a computer program opponent is minimal when the program is set to be playing at a level that much stronger than you are. Remember, the goal is to learn, not to win a lot of games. So if you do this you want the program set to a level a bit stronger than none stones better than you are. Not too much stronger than that so you get crushed. But stringer enough so that if you don't learn not to make these mistake moves you lose.

Sure, but connections tends to goes faster on the board then in my brain
I just joined a go club and they gave this book "Handicap GO, Elementary Go Series, Vol. 7".
I'm only on page 20, but I like it very much so far, I hope it will help me connecting my stones better.

I ofen play against igowin on iphone. I set the compteur to it's maximum level (3kyu) and with 19x19, I start to lose at 5 stones handicap...
I also like to play even game on 13x13, that fit well with the time I have in the train...
I lose most of the time, either I'm just to small (3 to 5 pts) or if I try to be more agressiv, I usually lose them all
BUT I still won 3-4 games... so I know I can beat him
