Overrunning 1B on a walk is not so simple:

BRD 108 points out that three sets of rules differ:

Fed: Batter-runner who overruns 1B on a walk in is peril of being put out.

NCAA: Batter-runner may overrun 1B on a walk provided he returns immediately and does not try to go to 2B.

OBR: "Same as NCAA," but then gives some "exceptions." One official interpretation, in direct contradiction, says BR cannot overrun 1B with impunity, as he is protected only to 1B. Another official interpretation says he is permitted to overrun if the pitch gets away from the catcher and he is hoping for a chance to get to 2B. A new interpretation says he cannot overrun if the catcher gloves the ball, but can overrun if the ball gets away from the catcher.

Oddly, in dealing with a base on balls, J/R says "the ball remains live and any runner who is tagged off base after touching or passing his awarded base is out. . . . However, the batter-runner is allowed to overrun 1B, provided he returns immediately to the base. [NFHS 8-2-6]."

But NFHS 8-2-6 says specifically, "A player who is awarded 1B on a base on balls does not have this right [to overrun]."

Also notice what is apparently a key difference in a related play (not a base on balls):

BRD 107:

Fed: A batter-runner may overrun first without peril of an out provided he does not attempt nor [sic] feint an attempt to go to second.

NCAA: The batter-runner is in jeopardy of an out only on an attempt (not a feint) to go to second.

OBR: Same as NCAA.

So NCAA and OBR distinguish between a feint (does not put the BR in jeopardy) and an attempt (does put the BR in jeopardy).
