Can someone give a review of this? I'm still a beginner but I would like to know what I did wrong.

Some sdk remarks. Hope they help!

28 E2 to block and cut off.
34 I would have played G4 instead. There's a massive wall, with only one little hole. Even if white does the best move, black still has a massive lead now.
44 R14 is the joseki here, it's perfectly fine in that situation
48 FAR too soon to play on the first line. Only slightly less bad than passing. You should have played Q18 in response to 47
49 white fails to take advantage of it, though
50 Since you were going to play R14 anyway.. Also note how Q13 helps guard the cut if Q15 isn't there.
65 White is pretty much passing.
66 You're not protecting much of anything with this, due to M2
67 Another white pass.
88 Nice catch!
104 In too deep.
118 Way too timid. You are playing near a group that's in atari! ALL the surrounding stones have at least three liberties, and the one in the middle has only two. This could not be safer. You need to think about the middle area, here. White's still wide open on the right!
150 H19! With G19, you're just giving up a point for nothing.
152 This is worse than passing. It's already connected.
158 Unnecessary reinforcement. L2 is definitely better than this.
166 Again worse than passing. That group is still in atari, and the surrounding stones have even more liberties now.
170 F7 is better for limiting the damage, here.
172 Still better (though it might be a ko fight now)
204 Not needed.

just a brief comment

#6 at Q3 not P3 makes it much harder on white

6: Consider descending to q3 instead. This is a very strong move for separating enemy stones. As a test for yourself, what move do you think he would play next if you played q3? Then what would you play? Then what would he play? And you? Keep going until you don't think either player needs to play locally. --- Does this imagined sequence look better or worse that what happened in the game?

18: This is called a "pushing fight". You're ahead (that is, if you play at d5 you're ahead, then he needs to play c5 just to catch up, then you can pull ahead again). Normally in a situation like this, you either extend (d5) or hane (c5). Which option looks better to you? Where does the sequence continue? Better or worse for you?


28: Do you see a way to keep d2 and f3 separated? Keeping enemy stones separated is very important.

32: What was your goal playing this stone? Locally, g4 looks much more important to me: if W breaks through, the consequences could be very dire. On the whole board, d16 is still the biggest point. Don't just follow W around!

34: Same comment as for 32. Good job on not just playing wherever W plays, though.

36: If you play d16 instead, where do you think W plays next? Which board looks better for B?

38: This is a little over-concentrated, since you already played r10. (Think of your stones as regiments in your army; do you want to squeeze them into as small as a space as possible, or spread them out to cover the entire front?) Why not develop the top side or the upper-upper right first?

44: Why did you connect? Connecting is very solid, but you have to have a specific threat in mind; defending when there's no threat is like jumping at shadows. What are you afraid of? Is there any way to protect against the cut while gaining influence?

48: Note that if you don't descend to q18, W has a big move p18. --- What was the thought behind :b48:? When the board is so incredibly empty, avoid moves on the first line unless the life of a group depends on it.

51: Look at the board right now. If you could move :b38: (q13) anywhere on the board, where would you want it? Would you keep it on q13?

52: This is fine (assuming you intentionally decided not to seal in the upper right corner), but I would approach from the other side, allowing you to use your wall to build a big moyo.

96: Is this move necessary right now? Are there any moves that prevent him from escaping, but also weaken W's other stones?

104: Did you get the result you wanted here? What other move could you make to keep W out of the lower right side?

166: Might as well pass.

170: Wrong direction. No sense in keeping W separated if he's about to connect himself by capturing part of the boundary of your territory.

172: What was your goal here? e7 and d8 are equally good for keeping those stones separated: Right now your priority is to keep W out of your territory.

End of comments.

I see two big mistakes.

1. White was fairly greedy about grabbing territory in the corners. You reacted timidly and failed to seal W in as much as you could have, so he both got his corners, and then later scraped out a little chunk of each side, too.

2. At move 94, I would have expected you to get at least 15 points of territory on the top side. Instead, you let W get a huge amount of territory there.

You made smaller mistakes, too, of course, which would have gotten you another four points and the game.

As an aside: I spent longer writing this review than you spent on the game. I think that you would have avoided some of the more obvious mistakes if you had been spending longer on each move. You spent about 3 seconds on each move. Since you had 20s of byo-yomi, you had no reason to ever spend less than 20s considering your move. If you played with what I consider normal time limits (20-30 minutes + 5 x 30s byo-yomi), you could have spent even longer on each move, and made fewer mistakes, and gained more from the review. Even if you enjoy playing blitz occasionally, I suggest in the future you only ask for reviews of more deliberate games.

I just looked at the very end of the game; you still have a chance to win big. Can you find it? I'll give you a hint if you're stuck:

Start at o2


Just so you know, if you play inside your own territory in Japanese rules, you lose a point.

Thanks a lot guys, I definitely need to stop being so click happy and slow down and really look at the board.

Since you already have r6 on the board, you might also consider B4 @ p3 instead of m3. This will protect your corner from invasion, and W is almost completely obligated to respond locally.

Typically, p3 will elicit a response of o4. Then, you can pincer those 2 stones, at L4 perhaps or somewhere in the region. W is again almost completely obligated to respond locally. Typically, W will respond by jumping out at O6. Now, you can go back and make reply to the approach at F3, but now because of your stone around L4, a pincer (h3 perhaps?) all of a sudden looks nice, because it both attacks the F3 stone and is an extension from the L4 stone.

In any case, there's a few things you can definitely take from this game.

* generally don't connect diagonally when another shape also works. B6, B22, B36, B56, B70, B150. I'm sure there are other examples in this game as well.

* look at the sequence at B28: should be at E2 instead of E3. W is forced to protect the D2 stone (usually at C2) otherwise B cuts at C2 and can capture the D2 stone. After W protects, B can play E3. This is a very common sequence, well worth recognizing.

* take the open corner at first opportunity. You make about 3 or 4 relatively small moves close to your own stones when a lot of points are available simply by playing first in the open corner.

* Don't make unnecessary protective moves in your own territory. B152, 154, 158, 162, 166, 204, 210 are all completely unnecessary moves inside your own territory. That's -7 points using Japanese scoring which is more than the margin of the game. (The trick is figuring out what's unnecessary ;)
