I'm playing black and I think I was playing good until 170 move where I lost control and focus. Lately I started to get good feel of territory and power, and I feel that I play much better than 17Kyu.
I'm looking forward to get a review from stronger player. Please give me advice what are my weaknesses and how to improve.
Thank you.

Re: Review request 17k vs 15k
At move 55, the correct play in this situation is A18. The move you played leads to...
Move 70, where white can kill you : find how.

Move 70: B19 and the group will have one eye.

Re: Review request 17k vs 15k
Below are some detailed comments on the beginning of the game. I think you are playing well so far.
If you want something to focus on, my biggest suggestion is that you should focus some study on the relative importance of moves. You make moves in the early part of the game that should be played later. Doing this cedes the more important moves you could be making to your opponent. In this game, moves 17-31 are what we call "slow". (9 is also slow, but it may not be as easy to see.) In ever case, there were much more important moves you could have made.
Two "rules of thumb" to help you figure out how to do this:
1. "corners, sides, then center". Generally, the priority in a game is playing in the corners (approach moves to the corner, defending against approach moves, or creating enclosures), then the sides (extensions, splitting moves, etc.), and only then moving up into the center. Obviously, there are time when this order does not hold. But at your level, I think you should follow this order unless there is a VERY compelling reason not to do so.
2. If your opponent attacks one of your groups early-ish in a game, ask yourself two questions -- (1.) Does the attack threaten the life of the group? and (2.) Does the attack allow your opponent to enclose (surround) your group so that your group no longer has the ability to extend? If the answer to both is "no", then you shouldn't respond and should play elsewhere. If the answer to 1 is "yes", then you have to defend. If the answer to 1 is "no" but 2 is "yes", then I'd err on the side of defending, but I'd at least think hard about how important my next move is. This should also be your decision calculus for choosing whether to attack a group early on. If your opponent's answer to your attack is "no" on both, then you probably shouldn't be attacking yet. Following this rule would have preventing you from playing 9 and 17-31.
That said, this something that has helped me, but since I came up with it, it may not be as useful to others. Now that I'm in the SDK range, I'm finding that every now and then, I should be defending some of my groups even when the answer to both is "no". However, this rule got me to this level!

Hi BlindGroup, glitchdot,
In post 4's SGF, in the
variation, 
R7 atari is a disaster for W:
B would not capture at T8 as shown in the SGF;
instead, B would extend at Q8, and W makes a very bad shape for himself.
W must atari at Q8 himself on ; only move.
This is indeed a standard sequence, and one must pay attention
to at R7 (disaster) vs. at Q8.

Oops! You're right. Thanks for correcting it.
