+### Week 9
+
+This week went well.
+I played a lot of games and had 28 wins, 6 losses, and 1 draw.
+My rapid rating went up a lotttt, and now I'm higher rated than my
+friend Will. :3
+
+I've reached the third (and final) "stage" of the puzzle book.
+I'm on target to finish the whole thing in the four weeks, though some
+of the remaining days might be a lot of work (I have to do ~28.5
+puzzles each remaining day).
+
+There's a chess.com official tournament for correspondence games for
+people rated under 1000 that started this morning as I write this (the
+morning after Week 9 ended).
+I look forward to seeing how I do in that (it'll take ages, as there's
+4528 players signed up..., 6 person group size, so it'll take 5 rounds,
+at up to 3 days a move).
+But that's more of a next week thing anyway!
+
+I started in on the new endgame book's "basic endings" chapter, which
+has been covering the basics of King + Pawn v. King endings so far.
+It's review for me, although its coverage makes some things clearer or
+more explicit than in my previous studies.
+
+I'm still not through the Sicilian Defense coverage from the openings
+book, which is more remarkable for the fact that it's being very
+summary about some major variations.
+
+As for my own openings, I've continued my experiment with replying
+classically to 1. e4 with e5 as black.
+I've been having difficulty with some of the sharper openings (the
+Vienna Game mostly this week), but it's otherwise been going pretty
+well.
+I might try learning the Nimzo-Indian and Queen's Indian as my
+responses to 1. d4.
+They're a bit more flexible and less focused on specific lines compared
+the Queen's Gambit Declined, which is kinda nice given that I rarely
+actually face 1. d4 openings (and even more rarely the Queen's Gambit).
+
+I've started a spreadsheet (going back to the start of this month,
+November) of my performance in different openings.
+My big weak spot definitely looks to be the sharper king's pawn (1. e4
+e5) openings, so depending on if they improve by the end of the month
+I might switch back to the Sicilian or put in a lot of effort next
+month on studying those.
+
+All in all, a great week for chess for me.
+I'll be writing next week's update from Argentina!
+
+### Week 10
+
+Blitz games didn't go well this week, as usual.
+Extracurricular rapid games did tho!
+
+The correspondence tournament is going well: so far I've won four games and
+lost zero so far (I also won two against the person in my group who
+just timed out against everybody, but those are hardly worth counting).
+As for the remaining four games in round 1: one I'm very ahead and
+should win; another I feel pretty good about; and the other two are
+very hard for me to judge (they're still early, material is even, and
+neither of us have a clearly better position).
+
+I didn't get in very much endgame study this week due to having just
+arrived in Argentina.
+In the openings book I made it on to the modern queen's pawn openings
+chapter, and just barely to the start of the covering of the Indian
+Defenses (1. d4 Nf6 openings).
+Looking forward to the rest of the coverage of those, as well as to
+reading about rarer defenses to 1. d4.
+
+Two weeks left!
+I have clearly improved a lot at rapid time controls so far!
+Not so much at blitz, but ah well!
+When it ends I'll definitely continue with another study plan, but I'm
+not yet sure if I'll try the more advanced variant of the beginner
+plan, or move on to the intermediate plan (I'm not at the suggested
+rating for that but still considering it), or come up with something
+custom. Tbd!
+
+### Week 11
+
+This was the penultimate week of the study plan!
+Played a fair number of rapid games, with more losses than I've usually
+had lately (although one of those was due to losing internet during the
+game, so idk if I would have lost it otherwise), and three hard-fought
+draws.
+The blitz day went alright, 2-2 and zero net effect on my rating.
+
+I finished up my first [woodpecker](#week-7) cycle and am two days into
+my second cycle now.
+I'm pretty sure I'm going significantly faster on the early
+mate in 1 problems, although it's hard to say just how much faster
+since they were also relatively fast last time around, and I didn't
+keep time records the first couple days of the first cycle.
+
+Since I've been in Argentina, for the playing through games from
+Logical Chess Move By Move, I've been doing that on a physical board
+with my fiancée, which is fun.
+It might be a little benefit in terms of requiring me to explain stuff
+sometimes to zir, who is less experienced with chess, though I'm not
+sure.
+
+I reached a decision about what plan to follow after the final week:
+the playing-lots-of-games version of the Intermediate plan from
+[ChessGoals][ChessGoals].
+I was talking about the decision with Sofía and was describing it, and
+explained how in addition to the base tasks for each day of each week,
+it has guidance on what to do as "extra credit" if you want to spend
+more time on chess.
+Which, guidance on how to prioritize additional time beyond the base
+tasks is exactly something I had considered a lack in the beginner
+plan!
+So, perfect for my preferences.
+That plan leaves certain topics a bit more at the student's discretion,
+by saying essentially "okay, you should pick a resource you want to use
+to study strategy" and then just sometimes having a "go study your
+strategy resource" task, so I'll have to pick things for those, which
+I'll probably do over this next week and be ready to start the new plan
+after that!
+
+The chess.com official correspondence tournament is going well.
+I have one game unfinished, with the others all won (two more
+unfortunately won due to a time-out by the opponent), and that last
+game is just a matter of time until I win.
+It will be a whiiiiile before the next round probably, but ah well.
+
+The openings book has just gotten to the Indian Defenses!
+Excited to learn more about the Nimzo and Queen's Indian.
+My own opening prep review has kinda fallen by the wayside, so I should
+probably get back in the habit of doing that.
+I'm working my way through the basic review in _100 Endgames You Must
+Know_ still.
+
+In extracurricular study news, I've been reading and enjoying
+Seirawan's other book _Play Winning Chess_.
+It starts out very basic (with an introduction explaining how the
+pieces move), but quickly moves into less simple topics.
+Its chapter structure is:
+
+1. The Evolution of Chess (introduces the game and discusses its
+ historical development, both in terms of rules and in terms of play
+ styles and theory).
+2. A chapter each on four key principles: force (what most would call
+ material, although Seirawan also uses it to discuss _local_
+ imbalances of force), time, space, and pawn structure. In addition
+ to explaining the principles, these chapters seem to go into more
+ detailed coverage of how to incorporate them into your play. For
+ example, the chapter on force includes sections on tactics and on
+ traps, the role of the king in the endgame, and the impact of
+ material advantages in the endgame.
+3. A chapter of annotated games, intended to illustrate the principles
+ and how they interact.
+4. A final chapter titled the Four Principles and You, which I don't
+ really know what it covers yet (since it isn't explained in the
+ introduction).
+
+There are also little quizzes to test yourself in the midst of each
+chapter, and a series of tests at the end of each chapter.
+Some of them so far have been pretty tough for an introductory book!
+Anyway, I'm midway through the chapter on force (currently at the
+section on traps), so I'm excited to read more. :)
+
+### Week 12: the End
+
+I've completed the study plan, and I'm very pleased with how it's gone.
+I'll be starting a new one tomorrow.
+I've also planned out a (5-week, to be reassessed and repeated after
+that) study plan for my Spanish learning, to emphasize how pleased I've
+been with this approach.
+
+I've gotten a lot better at chess, if not at blitz time controls, over
+these twelve weeks.
+Rating-wise, I've gone from 429 (or 508 after the first week) to 1023
+in Chess.com Rapid rating.
+Blitz has fallen from 686 after that good first week (before which I
+had not played any blitz) to 588, so it feels safe to say I haven't
+really improved at fast time controls;
+I still struggle to play quickly and not get into time pressure, and
+sometimes make horrific blunders due to trying to play quickly.
+I hadn't been tracking the progress of my daily rating, but I'm
+certainly also doing well at that.
+My daily rating was something like 326 at the start, and is now 1053.
+I've only lost a single daily game out of 30 I've played in that time.
+
+The books the study plan recommended have been very helpful, as has it
+just forcing me to play regularly.
+It is also true that the "extra-curricular" studies I've gotten up to
+have certainly contributed to my improvement, though they probably
+wouldn't have helped nearly as much without the opportunities to
+integrate them through actual play.
+As well, I suspect the study plan helped to ensure I maintained focus
+on improving at chess.
+
+Tomorrow I'll start with one of their intermediate plans. :)
