(;FF[4]GM[1]AP[gobandroid:0]SZ[19]DT[2015-01-24]PB[MHagan]PW[RS]KM[6.5]C[You fell behind early in this game. 24 was a mistake that you never really recovered from. And then 28 was not best; it damaged his position a bit, but it was in no way constructive regarding your own position - on the contrary.

Both these mistakes are entirely understandable and many players would make them. 28 in particular seems subtle. But they left you chasing the game.

36 is the 3rd mistake I want to pick on here. Again, it is understandable, the desire to settle your group is compelling. But you cannot do so if it allows your opponent to completely destroy your position.

46 is the same mistake in philosophy as 36. The fact that black did not press home his attack conceals the seriousness of your error!

The final point that I want to pick out whilst here at move zero, is to highlight the squeeze sequence you have available to you, on his 3 stones including 99, once you have 100 on the board. Given my article in the current journal, I thought I should mention this!];B[dp];W[pp];B[dd];W[pc];B[dj];W[qi];B[jp];W[fc];B[jd];W[cf]

(;W[ef]TR[mc]LB[dg:22]C[This loses you a lot of momentum. The proverb says not to refuse a ponnuki, but here it is attached to a group that is already alive and therefore most of the benefit of a ponnuki (hard to kill) is meaningless. Here, after 22, your group is already out towards the centre, and as you can see from the variations, he cannot easily shut you in even if he plays first now. Therefore you should play 24 in the top right to minimise his growing position and strengthen your corner stone, and also take a little bit of territory.];B[nc];W[pe];B[ne]
;W[fq]CR[cl][dl][cn][cm]TR[nq]SQ[pg]LB[dj:5][jp:7][qi:6]MA[kd][md]C[You have several ways into his position here, and he cannot prevent all of them, so you have a little time yet. What is clear is that when you do invade, you are going to come under a lot of pressure, and he can build influence while you are living or running.

Before you play 28, you can see that the likely result is black territory on the left running up to and connecting to 5, which at the moment is a little bit isolated, sitting in front of your strong position as it does. And 7 is also likely to get stronger, and in any event, 7 has lots of space so it is not easy to see how it can become very weak.

So consider the alternatives. An invasion on one of the circle points would be better, because at some point he will have to look after 5, and 5 can never do much for him because of your ponnuki.

Another alternative is the triangle point. After your invasion, almost regardless of where it is, the black position in the bottom left corner of the board is going to generate a lot of influence for him, and he is likely to invade your position on the right in return. Playing 28 on the triangle prepares for this. It also means that his stone 7 will be that little bit less secure, and importantly the natural extension from 7 to the triangle point will not be possible for him, so you are taking territory and preventing him taking it.

Finally, you can consider the squared point. It feels slow, but you can consider that it secures around 30 points in the top right, and means that you do not have to worry about your stone 6 when fighting on the right-hand side takes place. Finally, you will be strong enough in that part of the board to consider invading his position later, at say one of the cross points.

I think I would rank these alternatives from best to worst as follows: triangle, circles, square, your 28. But other players may differ; a lot depends upon personal style preferences.];B[eq];W[fp];B[cn];W[hq];B[iq];W[hp];B[nq]
;W[gm]TR[pq]MA[jn]LB[nq:35]CR[gr]C[The Joseki has 35 at the cross. Because he has not played there, you can defer playing 36 where you did. This is one of those occasions where you have to just say that your invading group is going to have to find a way to live somehow, you do not have time to look after it, something else is more urgent.

The point here is that you invaded with the intent of doing more damage to his position than the consequences do to your position. If you do not answer 35, the damage it and its follow-ups will do to you will be incalculable. Your 4 invading stones look heavy, but they can live by playing on the circle point (as I think you know) or they can run away. While you have miai for looking after them, you have time to answer 35.

If you answer 35 at the triangle, you are set up to invade his group behind 35, so at some point he will have to take time out to deal with that.];B[qn]LB[cn:31][dj:5][gm:36]C[He has secured territory in the bottom left, 31 has helped 5, your invading group is not fully settled, and your bottom right position is now being torn to shreds.

;W[gr]TR[pm][ql]LB[qn:37]C[Q7 or R8 is screamingly urgent now. You have to leave your invading group to look after itself and settle your bottom right group by attacking 37, or suffer an attack like that shown in the variation from the next move.]
(;B[er]C[The variation for this move is just to illustrate the sort of attack that black has available to him.]TR[ro];W[ir]LB[gm:36]C[Again my point that you must let this group look after itself.

(;W[ql]TR[sk]C[It's not a big deal now, but you have just played 108 in your own territory. There is no need to be so submissive. You can play at the triangle, which threatens to capture the black stone at T 10. If black tries to cut you, he gets nowhere. See variation.];B[fn];W[gn];B[fo];W[go];B[ep]

;W[hg]SQ[li]MA[he][hf][ie][if]LB[kf:106][lf:80][ih:115][lg:103][lh:101]CR[jg]C[I am not sure if you are trying to cut off the 3 black stones 101, 103, 115, or prevent black making territory at the crosses.

If the former, it is just an error in reading (because 116 induces 117 as in the game, which threatens to rescue 101 and 103 - see variation from 118).

If the latter, it is normally enough to prevent black rescuing 101 and 103 by black playing on the circled point. Taking a liberty off his 2 stones does that; playing on the squared point is probably best. Then 106 and 80, together with your potential to play 116 later, mean that he has no significant territorial aspirations here.

If he plays 117 at the circle now in response to your 116, a very awkward fight develops. You may be able to win it, but it is not normally a good idea to take the risk.

You will have noticed that I said "normally" twice above! You have about 15 points in the top left, 25 in the bottom right, 5 points including prisoners in your bottom centre, and say 8 in the top right, plus Komi, making 15. 15+25+5+15=60. He has about 35 in the bottom left, and about 30 across the top. So he has more than you even before you count his bottom right group! It follows that you need to do more than play a good endgame, and in this game, now, it is probably a good idea to try and cut off his 3 stones in the centre, even if accurate reading suggests that you can't. What else can you do that might actually win you the game?]TR[hd][jd][ld]
