A 2-33 should be landed just like any other "nose dragger

Really? The correct landing procedure for a 2-33 (and Blanik) is a
recipe for high energy landings in K-21s or G-103s (or worse case, a
high sink rate bounced landing leading to the infamous "galloping
Grob"!). I hope you have a long runway and a big budget for brake
pads!

Some older gliders (and not all nose draggers) require a flown on
landing - tail low, but on the main wheel - due to the tail wheel not
being stressed for landing forces. Examples are the 2-33 and Blanik
(note, one is a nose dragger, one a tail dragger). This is similar in
concept to a wheel landing in a taildragger airplane - or a somewhat
flat normal landing in a tricycle-geared airplane. The trick is that
once you have established the pitch attitude for touchdown, you can't
continue to increase the angle of attack to slow down or you will
touch the weak tail wheel/skid too early, so some judgement and skill
is required.

The later generation of trainers, whether nose draggers (k-21, g-103)
or tail draggers (DG-500/1000, Duo) are designed to land main and tail
at the same time - minimum energy landings - the equivalent of a 3-
point landing in a taildragger airplane. This is also the way almost
all current single seat gliders are designed to be landed, for obvious
reasons - gliders are now heavier and land faster, and need to be
landed at the slowest possible speed in an off-field landing.

That is one of the reasons the 2-33 is a poor trainer for today's
glider pilots (assuming they intend to move on to something more
interesting than a 1-26). If all training is done in a 2-33 (or
Blanik, to be fair), then a careful checkout in a modern glider is
essential to properly prepare the transitioning pilot for the landing
characteristics of most modern gliders.

Just to keep this discussion interesting, we can now argue whether a
low energy tailwheel-first landing is OK or bad for a modern glider
(assuming a reasonable sink rate at touchdown)...
