Positioning Questions

[Chess Ref]

Okay I got my questions answered about pick off attempt at 1B. Now I need to move on to 2b and 3B.

I am in C slot. R1 on 2B. When there is a pick off attempt at 2B should I move parallel to basepath or should I move into the basepath ? My thinking is if F4 is making the play move towards basepath for the angle . If F6 is making the play I should move parallel ,kinda with the SS.

I am C slot. Runner on 3B. F5 making the play I step into basepath for the angle. If F6 is making the play I move parallel to basepath to get the better angle.

i know these sound like basic positioning questions but this is only my second year and at times I find myself not real sure on how to get the best angle on these sitchs. So feedback is welcomed.
