This guide is for unlocking the Acknowledged Expert (and related) achievement(s) in 1931: Scheherazade at the Library of Pergamum. As the non-trivial part of this achievement is getting 100 Knowledge points, the guide is mostly a reference to the places where these points can be found. While the guide has been tested to work, 1931 can be a buggy game at times, and your mileage may vary. This guide is not intended to be a comprehensive listing of available Knowledge points, so you may find points that aren't referenced here. If you do, feel free to drop me a line and I'll give you credit for your discovery.

• Before attempting this achievement, you should have a good understanding of the game, including a good feel for time management, general knowledge of the Capers and cutscenes that occur in each area, and a grasp of how to clear these in a way that gets you the points you need without getting stuck too often on Obstacles. This guide is not intended for beginners; people new to 1931 should give the game a few playthroughs and at least try to get the various Dream achievements first.
  
• An Acknowledged Expert playthrough (as well as playthroughs for any other difficult achievement) should be done in Easy mode. 1931 is hard enough without adding modifiers to Obstacles.
  
• While the main part of the guide tells you exactly what Capers contain Knowledge points, you will still need to go through all of the Capers (and the cutscenes) that the game has to offer unless you have a precise understanding of how Capers unlock. This is because many Capers require you to have completed previous Capers and cutscenes to be available (e.g. most if not all love-interest-based Capers require the previous Capers for that character to have been done). As such, an Acknowledged Expert playthrough can double as an All Adventures! playthrough, but note that the latter achievement is glitchy and may not unlock for you regardless.
  
• You should probably focus on doing the Acknowledged Expert achievement to the exclusion of other attribute-based achievements in your playthrough. Not only is it difficult to get a lot of points in other attributes while focusing on getting Knowledge points, but a number of Knowledge points are mutually exclusive to points in other attributes, meaning that it's likely impossible to get the achievements for more than one attribute at a time. That said, you should probably try to get a moderate amount of Dream of Family points (and don't pursue a romance) in order to give yourself more Inspiration slots.
  
• As noted above, the difficult part of this achievement is getting the 100 Knowledge points. Beyond that, all you have to do is train up all of the Knowledge skills (easily done once you've gotten a lot of Knowledge points) and play until you reach the end of the game on June 13, 1931. You don't even need a good ending for the achievement to the best of my knowledge, but you'll probably get one anyway due to the numbers of Relationship points you'll get just for playing through all the Capers.

For the sake of brevity, this guide uses a particular format to relate the location of each Knowledge point. The general case looks like this:


where n is the number of points you get, Caper is an identifying code word for the Caper (usually the name of the Caper's central character or a keyword in the Caper's title or the name of the Adventure), x is the number of the Obstacle for which the point(s) is/are given, and Obstacle Requirements is what check needs to be successfully done to get the point(s). For example:


says that you can get a Knowledge point on the first obstacle of Anna's Adventure in that region by successfully passing either an Awareness or a Patience check. Some Obstacles must be completed in a specific way to give you a Knowledge point; those cases look like this:


There are other cases where it's not an Obstacle that gets you a point, but a dialogue option. These cases look like this:


which here means that you get a Knowledge point in Roland's Adventure in that region by picking any dialogue option when you get to the second branchpoint after the second obstacle.

There are sometimes paths to get Knowledge points that are more complicated than simply passing an Obstacle or picking a single dialogue option. These cases look something like this:


where you have to make a specific dialogue choice then successfully complete a Deduction or Perception check (which may occur at any time after the dialogue choice). When there are multiple mutually exclusive paths to get Knwoledge points, the "best" path in the opinion of the guide author (usually in terms of lower Stress points or extra points in other attributes) is listed.

Thank you for reading this guide. I hope it helps you unlock this particularly difficult achievement. Please let me know any questions or comments you have regarding this guide

Thanks also to the Scheherazade Wiki at http://applesauce.wikia.com/wiki/Scheherazade_Wiki for the locations of a handful of points that I had missed in the non-New-York areas. (There are still a couple of points or so this guide is missing in New York, but I didn't see the necessity of searching through and adding them.)
