..or, a tail wheel lock. Code and try it. ;-)
..also, some have steered tailwheels, some are springloaded,
and, some of these again can be locked straight, and released
to free-swivel too. ;-)
..I believe the RL DC-3's used tail wheel locking, the RL AT-6
Texan, P-51, P-47 and many more, also use(d) them.
..the idea behind tail wheel lock is to keep the plane straight
down the runway during takeoff, until you have enough airspeed to
lift the tail. On landing, you want the tailwheel locked to avoid
groundlooping, until you are turning off the runway onto some
taxiway or some such.
..differential braking with a locked tail wheel will be far
less dramatic, as they in RL rely on differential friction and
tire hysteris, to turn the plane. Somewhat slowly. ;-)
..most taildraggers can be planted tailwheel-first, to
prevent bounces, again easier in RL with a locked tailwheel.
("One pointers" are more intimidating to do in RL taildraggers,
as most use "speedometers" rather than AOA instrumentation, as
in "you're _close_ to a stall on approach" and without exact
knowledge.)

Scenarios always come in sets of three:
best case, worst case, and just in case.
