;W[fq]C[Yang: Right idea, but still the wrong side. As long as it is safe, invade where they have more potential (I was too worried about letting black consolidate some of his territory while attacking my weak group).]

;B[mp]LB[jr:A]C[Yang: Still K2 keima for white (repeat this every move for the next 10 or so). In this case I was a little worried about the double attack and reasoned that I was already safe w/o k2 (wrong). If black double approaches it should be easy though,]

(;W[od]LB[nc:A][od:B]C[Yang: White should think about this non-joseki move. Even with the black stones around H15 and O10 white should still try to get off the 3rd line and put pressure back on black here.]))
(;W[jl]LB[jl:B][gn:A]C[Yang: This is the only move. White can now peep for eyes or move out. Having eyes is nice, but white makes black so much stronger with the sequence in game that its unplayable.]))
(;B[pr]LB[kq:A][pr:B]C[Yang: This is the move you have to worry about. I did in fact worry about this move, which is why I had to answer the move in game by defending the corner.]))
(;W[qq]LB[oq:A][qq:B]C[Yang: White should keep the corner. Normally this exchange can help black settle his stones a bit, but here it does almost nothing for him because K2 is still open. Hane in game is an overplay.]

;W[oo]C[Yang: "You are 4 dan right? This should be easy for you now!". Yeah, point taken.]))
(;W[jr]LB[io:A][jr:B]C[Yang: This is the all-important move for white. This is bigger than every move I played for the next ten moves or so. I have to remember that my group was an invasion, so seek safety. Once I have this black is floating and I can act with impunity.]))
(;B[iq]LB[fn:A][iq:B]C[Yang: Black must play here, this move is joseki for a reason ;) He asked me what my plan was if black played this way,]
;W[io]
;B[jo]
;W[in]C[I was going to play this way.]))
(;B[cq]LB[gj:A][cq:B]C[Yang: Black could just play here to punish white for not invading.]))
(;W[cn]LB[jj:A][cn:B]C[Yang: It is still safe to invade here, and this is where black has the most potential. White should jump in because it will be harder the longer he waits.]))
(;W[bc]LB[bc:B][gc:A]C[Yang: This joseki choice is better for white here. I have a few misgivings about the aji of the F17 stone but Yang felt this is the only way since I can either get sente or a start on reducing the moyo.]))
(;W[fe]LB[fe:B][qi:A]
;B[df]
;W[fg]
;B[dh]C[Yang: White can play this way if wants to limit the moyo. In retrospect you can see that F15 was the vital point for both sides to controlling the developement of the game.]))
