Life In 19x19

Here is a game in which I ended up with a big semeai and lots of dead stones. In the end I lost the game by 23.5 points. Much obliged in advance for your comments.

shape problem; not thinking bigger picture.
If kicks at P3, and extends to o4,
then jump to L5 (stronger shape than K5) to split and attack both W groups.

If you get the chance to also kick E3, it's painful for W to extend to F4.

N4 -- W gives you an excellent opportunity to kill, why not ?

: I would have looked at O4 and R7.

I find somehow hard to criticise.

Feels awkward to me. My instinct is F10 cap. White G8 aims to save H4 while sneaking up on killing D13 on a large scale by being implicitly connected to C10. But it is too thin. My move is E10.

I would play L5.

has the weakness of white G6. This kind of aji is why I would connect at .

I am at a total loss of where to play. G6?
