Oh dear! So much to say and so little time!
While playable, this move is rarely seen except in special cases. It is almost always on the third line for balance.
Better at R4. The side is too wide to expect to make a moyo, which is essentially what this move is trying to do.
Far too wide. Has to be at O16 to secure a large corner.
Shoud be on the third line, both for balance with the stones above and to threaten R6.
contact moves, especially this early in the game, are generally considered defensive. While the two white stones are not strong they are not so weak as to need an immediate defensive. I would have considered wR4, bR3, wR5, bR2, wR11.
Better at P6 to prevent the connection and huge territory from bR6.
Better at R6 to prevent the connection and threaten both Q9 and S4.
R6 still huge. This move is also a bit vague, an inbetween move. D6 and C14 both feel better to me.
Very strange move.
Yo cannot leave the 2 stones at this point. You allow black a free hane at each end. You have to extend to either D12 (better) or D9.
LIkewise, black should not leave them. This point is not urgent: F17 and O17 would both be better. Black should play D9 to start forming a moyo.
It is hard to say this is wrong, but the solid connection is stronger and allows more resistance to a black move at J16,
The shape move here is C17, which is very big. But after what was said above it is hard to argue with finally playing around here, although D12 looks stronger. M3 feels better to me but that moves allows bR6. So perhaps play R7 first to prevent that connection and then play M3.
Why not R6?
Too late now as it is no longetr sente.
I think it is better to play O18 to connect the two groups. If black get to play this move it is not a big as it looks as all the black stones would be overconcentrated.
S8 is better shape.
Why? This give black a free stone. Just play D3.
You are not strong enough to cut.
This is a common mistake for weaker players. Black has to come back to protect and so should do so directly without the atari. D12 would be better as it stops the white ladder at F10 and break white into 3 grousp.
This move is huge. If two dan players took over at this point I would call it the winning move.
Not needed. The two stone capture next to is not under threat. Conect at C18 if you are concerned about the corner group (you should be). otherwise play F8.
Very bad move as it gains nothing. O18 is the point to secure this group.I could comment on almost all the remaining moves but for lack of time. This should give you a lot to think about.
