;W[dq]LB[ip:A]C[Folks who start with double 5-4 like to add a stone between them, which really makes things much more complicated. I jumped in before he could do so to keep the game simpler.]
;B[fp]
;W[co]
;B[cp]LB[jq:A]C[If black had time to add a stone around A, the usual joseki wouldn't be good for me. That is why I jumped in right away. This should be fine.]
;W[dp]C[This is a joseki that lower SDK must memorize. You won't discover it on your own in a tournament.]

(;W[gq]LB[cq:B][dq:A]C[All this is perfectly fine. Joseki.

This last move assures that white gets out with his group, and that A has extra liberties to kill B, if black doesn't defend soon.]
;B[hp]LB[gq:A][dr:B]
(;W[hr]C[I frankly forgot the normal joseki, and responded to A.

It turns out this move has (rarely) been played by pros. I assume it's when the right side is more important, or maybe when black has further reinforcements on the righ, so white needs to be super cautious, or when white already has helper stones on the left.

Anyway, none of those are the case here, and I should have played normally.]
;B[hq]
;W[ir]
;B[cl]C[Because I prematurely got out on the bottom, black was able to play this.

First I thought, "That's not joseki!" Then I realized that I was supposed to play here first.

I got very frustrated and played an amazingly bad move.

So key lesson. When things on the go board get a little bad, don't go on tilt! Step away from the board. Take a deep breath, and make the best of it that you can.]
;W[bm]C[White's first move was fine. This threatens to split black, but more importantly, hurts his shape...]
;B[bl]
(;W[al]C[This move was terribly bad, and played far too quickly.]
;B[dm]
;W[bk]
;B[ck]
(;W[pd]C[At this point, I couldn't find a continuation that let white connect out, so tenukied.

It turns out, white could connect to A, though that isn't necessarily best (see variation)

The situation is REALLY bad. Black got territory he shouldn't have, and thickness, too.

Still the game isn't over, for amateurs. White needs to play flexibly, make the board complicated, and try to encourage black to make a mistake of similar magnitude. 

I was able to create complications, but my opponent played with skill, and avoided making a game losing blunder.
