Official baseball rules in play: Runner on first. Right-handed pitcher in set position. Pitcher lifts front leg and does spin pick off move to second base. R1 breaks to steal second on pitcher's move and is tagged out at second.
seems legal to me based on 8.05 (d) and 8.05 comment (b)
Also, if R1 is not stealing, is it still legal based on 8.05 comment (b)?
