Hi I'm a 7k, was black in this game. Playing white who is a 6k. I won by about 5 points but I feel sort of disappointed in this game. Feels like I was playing very sluggishly for some reason and I'm not sure why. Any/all comments would be super helpful. (the comments in the game are my own quick review)

Some comments:

Move 5 is fine. Black could also try and set up a mini chinese on the top side, but that's a very different strategy.

Moves 7 and 9: Because of the cross opening, there will likely be a big battle over the center and many smaller groups. It may be better to play these high to influence the battle in the center more.

Move 11: I agree, though I don't think the two space jump is unplayable.

Move 13: I don't like this move. It certainly doesn't try to take the corner. I think white picked the wrong direction to approach from, and I would be inclined to kick white at R5, looking for white to extend to Q6 and black to make a one space jump to O4 in response. The corner is still a bit open, but white is left heavy and under attack. There would be a fight concerning the thinness of the black 2 space jump at this point, but I think black should come out okay.

Move 15: I like Q6. If white hanes at Q8, black clamps at Q9, fixing his shape in the process, and then connects with P9 or cuts.

Move 39: Is this the thinnest spot to invade white? White ignored black's approach at F3, so I'd rather do something to the bottom left. Locally, approaching from the top side or with an invasion attaching under the 4-4 might be better.

Move 45: This sequence seems fine. White's made terribly broken shape, though black's groups are not completely safe either.

Move 47: Black's two groups are split too, though. By taking the corner, black is creating a third weak group while strengthening white to counterattack.

Move 71: Usually black hanes here. Black has to be careful not to harm his bottom side group by strengthening white to invade.

Move 93: I think this move is okay. It helps black's right side group, which should live but small, and reduces white's center. J18 is way too deep. J13 also seems dicey and unnecessary.

Later on, you also suggest deep unsupported invasions that are unnecessary. Invasions are dicey. Just count and see if you are ahead, or if you can be ahead with a moderate reduction from the outside. Overall, I think this game was won on endgame. Black's seemed much stronger than white's. White was very passive when he should have tenukied for mutual damage or to intersperse sente moves.

I've reviewed the first 15 moves of the game. After that, it became really hard to continue to review, because when evaluating a position where both players have made mistakes it becomes a lot harder to decide what is best. Still, hopefully you'll find some value in this small review.

Thanks Skydyr! I had a quick follow-up question though. When the game starts out as a fighting game because of the cross opening, is it generally a good idea to try to build influence more towards the center compared to games that dont start as a cross opening?

Thanks Dusk Eagle! As for move 13, I was thinking that was a very bad move. Like Skydyr suggested, I was thinking of the same variation as which I thought was the beginning of a corner taking joseki: I understand your point with joseki stuff though. I sometimes feel like I'm putting too much trust into using them in games as soon as I remember one.

You mention the shapes being so foreign after move 15. It's a broad question but what is the best way to practice to get over this problem?

It's more a question of my own abilities as a reviewer to decide what is a good result for each player. Once the shapes reach a certain point, I can still read out a ton of variations for both players, but I struggle with evaluating what is the best result out of what I've read, since no result is perfect. So I spent quite a while looking at that position, but in the end couldn't come up with anything I could confidently say was a correct way to play for both players. Really, it's more of a problem with me than with you.

Well, honestly if you're going to have a double wing formation with a hoshi stone, you probably want the wings to be on the fourth line anyways. Putting them on the third line is somewhat contrary to the idea behind the 4-4 stone. The corner is still open, so if white invades, you don't want to also allow white to be able to keep you pressed down on the third line, leaving your stones inefficient. If white invades, he helps solidify the rest of the moyo, so you want to get as much as possible.

Really, once you set up a double wing formation, it kind of asks white to invade one side or the corner in exchange for consolidating the other, so you want to gear your plays to take that into account as the expected result.

You'll notice that I skipped large portions of the fighting as well when I commented. :p
