For OBR, the penalty for type B OBS is to award bases so as to nullify the obstruction. The obstruction did not prevent R1 from returning to 2B, which he had to do as a result of R2's choice to remain at 3B. Indeed, the hindrance might have helped R1. I would therefore not make an award in this case: R1's out stands.

Let me try again.

FED

Runner on 2nd base stops at third base.
Runner on 1st is the one that is obstructed after rounding 2nd and is ultimately thrown out going back to 2nd base. 3rd base was occupied which is why R1 ended up trying to get back to 2nd but was tagged out.
