The two players alternately choose a closed sub-interval of the 
interval. If the w-sequence of sub-intervals so obtained converges
to a point in some given BIG set, then B wins; otherwise A wins.

Mazur proved that if the target set was category-large, then B can
win (if he has first move). There is no similar result for measure.

Does "there is no similar result for measure" mean that there is a 
target set whose complement is measure 0, which A, moving 2nd, can 
always avoid? Or does it just mean that the question is open?
