This is the diagram Stean has at the top of page 89.
Simple Chess (Stean) Errata

Tag for interests. I'm going to go through my copy with whiteout and fix it, if I can get the complete list of errors.
I think it's fine, isn't it?
The moves make no sense. They aren't legal moves. I was hoping someone with the descriptive notation edition might have the correct moves.
Just an added note. I did find the corrections of Dr. Salawu in the reviews.
A few, inconsequential errors that Fred introduced are: on page 5, he wrote "a piece beyond the second rate" when he meant "a piece beyond the second rank" as Stean had written. Fred erred in the fifth line from the bottom of page 12 with `win again a ...' where `win against a ...' had been correct. On page 102, the second line should have started, "After g6 and Bg7" rather than "After g6 and Bb7." On page 107, Fred wrote "This is what we are talking about when we saw things like ..." when he meant "when we say things like." An earlier reviewer mentioned the misuse of the word `complication' in "successful complication" on page 121 when "successful completion" was written in the earlier edition. That reviewer then went on to rate the book low for poor editing. Do you think Stean's magnificent elucidation of basic chess strategy should suffer from minor oversights of an editor? The third line from the bottom of page 135 could have done without the `of' and the last-but-one line on page 137 should have included the word `starting' in place of `startling.'
I just received a copy of "Simple Chess" by Michael Stean and found a list of corrections at this link:

He says this is an extention of the list of typos started by Dr. Salawu. I can't seem to find a link to this.
I found an error on page 89 not mentioned in the corrections and can't figure out what the moves are. Here is how the game starts out with Stean's comments.
1.a4 e6
Black wants to hold his Queedside together by Nd7 without allowing a White Knight to jump into d5.
2.a5 Nd7
Taking the a Pawn would split up Black's Pawns too much, e.g. 2...bxa5? 3.Nb5 Qe7 4.Rxa5 and the other a Pawn will not last long either.
3.axb6 axb6 4.Rba3
With an obvious invasion threat on the seventh rank. Despite only having one file and one weakness to work on, White can make life very uncomfortable for his opposite number.
4...Qc6
As you can see the moves make no sense. Has anyone figured out the correct moves? Thanks for any replies.
