Catcher's Obstruction

[thumpferee]

Lil' help here please!

I know I had this on a thread b4 but can't find it and can't find a case play to help me understand.

Situation:

Quest 1: R1 on 1st is stealing on the pitch. Catcher obstructs swing of B2 and there is no throw made to 2nd to attempt to retire runner.

Does Manager have choice on this play?

ex1: Since R1 was stealing on the play, can Manager decide to have R1 put on 2nd and leave B2 at bat because he may be the best hitter? And, if so, is the pitch a ball, strike, or a no pitch?

or,

ex2: Have R1 put on 2nd and B2 put on 1st?

or, is there no choice here?

R1 to 2nd, B2 to 1st?

Quest 2: Same situation accept catcher is hurt and runner continues to third base.

Would PU call Time and Dead Ball after
R1 reached 2nd?

or,

Let play continue until runner/runners have stopped advancing?
