I would like to mention here a great book I have been looking at recently,- the Even haAzel אבן האזל  by ר' איסר מלצר Rav Isar Meltzer who was a friend of Rav Shach. This book fills in a lot of details which you might not get in the Avi Ezri. For instance, I have been looking at chap 7 halacha 12 of Monetary Damages. I think it is clear  that Rav Shach goes into some of these details in laws of Robbery, but the book of Rav Meltzer goes into greater  detail. [In Laws of Robbery 9 , halacha 8 Rav Shach comes to the same sort of basic principles that Rav Isar Melzer arrives at.   ]
