this is a game I played in the pub yesterday. I am 3 kyu KGs right now (bordering to 2 kyu) and my opponent is a strong 4 kyu KGS. We played the game without time controls (we were too lazy to set up the clock) and so it took even longer than a tournament game. I would be gratefull to receive some comments on where we went wrong and what we can improve. (Especially in the opening and early middle game.)
So, anyways, after Nigiri, I played White.
I felt black came out better after the opening and I was struggeling hard to get something going. In the middle game, due to a misjudgements by black, I was able to capture some of his stones, which was sort of the turning point of the game.

;B[pf]C[I felt that white should rather have played at M17. In the game however, black still got a good result ...]
;W[lc]C[This move felt good ...
(I thought black would reinforce at K17 and I would slide to R18.)]
;B[pc]C[... until black played this. I now pondered to attack his group with J18. Maybe I should have played it, but I feared that black could then keep me low and possibly surround me.]
;W[od]C[So I played this standard move.]
;B[qj]
;W[nq]C[Now that I look at it, I probably should have attacked at J18 instead, at the same time strengthening my own group.]

;W[le]C[For the moment, this board position looks equal.]
;B[mo]C[This move felt very strong and I began to fear a black moyo.]

;B[kn]
;W[db]C[I suspected this to be sente agains the black group]
;B[cn]
;W[cl]C[Not sure if this is a good move - just felt I had to play something a little bit agressive instead of just playing at F3 or F4.]

;B[in]C[However, black got to take this key-point ... which was painful. Maybe my original pincer at C8 was not such good idea?]
;W[ho]C[And I still felt I had to reply, allowing black to keep sente.]
;B[hn]C[I felt I could not allow black to keep sente]
;W[fe]C[I wanted to profit from black's earlier tenunki after D18 and use the E7 stone to build something on the left.]
;B[jf]
;W[lg]C[This felt good - going into black's center and keeping the pressure on the group on the left]
;B[li]C[A good move by black, I think. I was a bit clueless on how to answer.]
;W[kk]C[Probably an overplay. What if black answers at K10?]
;B[ji]C[This felt submissive by black.]

Invading the right at A (R12) or B (R8) seems too risky.
Mutal destruction at C (N9)?
Strengthening at D (O14)?]
