……那个表示它是一个数值占位符的矩形？ > 回答答案是44的学生，那些回答26的学生是怎么得出他们的答案的？ 我在爱德华·拉斯克（Edward Lasker）的《国际象棋：完全自学指南》（Chess: The Complete Self-Tutor）中看到了这种方法的一个绝佳范例。针对一道象棋残局题，他不仅给出正确答案，还会告诉你答案中做对的部分，以及为了得到更佳答案漏掉了什么。……
…rectangle that shows that it's a placeholder for a value? > Students who said the answer was 44, how did the students who said 26 arrive at their answer? I came across a great example of this approach in Chess: The Complete Self-Tutor by Edward Lasker. Instead of just showing the right answer for a chess puzzle, he tells you what you did right in your answer and what you missed in getting an even better answer.…

我觉得 HAKMEM 里有个拼写/印刷错误：第70项据称是盗自拉斯克《Chess for Fun, Chess for Blood》的一道象棋题目。据我所知，这是拉斯克书里第145页上的第66题 [1]。然而，里面有一个致命错误：白方的象……
I think there's a typo in HAKMEM: item 70 is a chess problem purportedly stolen from Lasker's Chess for Fun, Chess for Blood. As far as I can tell, it is problem 66 from Lasker's book, on page 145 [1]. However, there's a crucial mistake: the white bishop…
第70项，那道“盗自拉斯克《Chess for Fun, Chess for Blood》”的象棋题目，其实是那本书里的第66题 [1]。备忘录里陈述的题目有问题：白象是在第8横排，而不是第7横排，所以……
Item 70, The chess problem "stolen from Chess for Fun, Chess for Blood" by Lasker is problem 66 from that book [1]. The problem as stated in the memo is wrong: the white bishop is on the eighth rank, not the seventh, so…
The chess problem described in item 70 always surprised me. It just didn't seem worthy of inclusion. A few years ago I happened across the book by Lasker that it was drawn from and found that they'd made a typo…

嗯，那本象棋的书还在印：https://www.amazon.co.uk/CHESS-COMPLETE-SELF-TUTOR-Self-Tuto... 而且我能在二手网站（比如 ABE books）上看到其他几本，价格不一，但往往都不算太贵，……

第 70 条里描述的那个国际象棋问题一直让我很惊讶。它看起来根本不值得收录。几年前我偶然翻到它出自的 Lasker 那本书，发现他们打错了一个字……
