We shall see who's ...

R1 scores, R2 to 3rd.

Because, it's two bases from time of throw (TOT), R's were at 2nd and 3rd from what I'm reading at TOT.

If you trying to glean something about a first play by an infielder?

Because all runners including the B had reached their next base, the first play by an infielder won't apply.

The way I understand it to be: B2 (the hint: is now R2) acheived 1st. Then the throw was made. 2 bases, so R1 scores ... and R2 to 3rd. The key here is that B2 had acquired 1st. I wonder how many times, at any level, this has been done incorrectly. I wonder if I have appllied it incorrectly ... but I can't remmeber it ever happening.

Where was R1 at the time of the throw?

If R1 had touched second at the time of the throw then he scores and B/R goes to third. If R1 had not touched second then he goes to third and B/R gets second.

Also, once a B becomes a B/R (with the right to advance) he remains a B/R until he is put out or playing action ends. He doesn't become an R simply because he touched first base.
