Don't we all just love questions about OBS?

Yeah, I remember now. The problem with that is that the "between the bases" clause DOES trump the "nullify the effect" purpose everywhere else.

Example, a runner attempts to steal 2B, and the throw to F6, who is covering the base, has her dead, but she is obstructed by F4. The result is not to nullify the effect of the obstruction (since that would be to rule her out at 2B, which would have been the result had there been no obstruction), but to invoke the "between the bases" rule and place her back on 1B.
