Circle 4 Begins
I did a review of Step 1 by going to the first problem I got wrong last time, backing up 30 problems, and then doing all the problems from that point on, 30 seconds per problem. I got everything right except one problem which TCT marked as "The played move is not bad". That's really rare, and it doesn't effect the score when it happens :-D.
I am slipping a bit in Step 2, almost never using the allotted time per move, though result being I got a couple wrong that I got right last time. Vigilance seems called for.
Step 2, Exercise 4c, Problem 3 marks Ne4 and Ba6 as wrong when it's the best. It only accepts e5, which obviously is the most straightforward move.

It would be great if we compiled a list of TCT errors, or alternative equally strong (or slightly better) moves. If I am less lazy in the future, I'll create a post (with link on the sidebar) there just for purposes of listing TCT errors.
