Appeal a turn toward second.

While BR is approximate 30 or 40 feet down the line, she makes an attempt for 2B and then turns back toward 1B and just stops. F3 while holding the ball steps on 1B and appeals that F3 has made an attempt for second. BU rules B2 is out on appeal since F3 is not expected to chase B2 into right field to tag her out, especially with a runner at third.

Anyone disagree?

OK, here is the OP again.

If BR was tagged out after "she makes an attempt for 2B", that is an out because she has forfeited her exemption on the overrun.

The possibility of the BR advancing toward 2nd eliminates any non-tag appeal at 1st;
and by 8-7-4-c in the LBR, she must "advance non-stop to second base".

R1 at 3rd has no beariing on the ruling.

The OP says "F3 is not expected to chase B2". If so, that could change the outcome. Where is it written?
