If one began studying Torah (or other activities) while it was still day, must one stop when the time for bedikat chametz arrives?

PesachBedikat Chametz

Synopsis

The Mechaber rules that if one started studying while it was still day (b'od yom), one need not stop. The Rema disagrees, saying one must stop, and states this is the primary ruling. Major dispute between the two positions, with the Taz, Magen Avraham, and Gra analyzing the underlying reasoning.
