Well, alrighteeee then...
So I've begun a CQL tutorial with 100+ examples planned. The tutorial
is in its early stages and will likely be a work in progress for some
months to come, covering CQLv5 and CQLv6 queries for themes and patterns
applicable to regular over-the-board games and expanding to include
queries oriented toward the chess problem domain.
There are currently templates for 50+ examples in place with a dozen or
so fleshed out to varying degrees to give a flavor of where I'm headed
with this thing. Criticisms and ideas for additional examples are
welcome. CQL has a steep learning curve but I'm attempting to
demonstrate that it is well worth the effort even outside of the
composition domain.

The CQL reference manual already includes many example queries oriented
toward compositional themes. In addition to a number of simple CQL
constructs, I'm looking at compiling a decent sample of queries for
tactical maneuvers and classic positional themes which one might find in
an OTB game.
For example, I've assembled queries for a smothered mate, skewered king,
answering check with mate, pins, fianchettoed bishops, discovered check
answered by discovered check, overloaded pieces, knight outposts,
deflections, decoys and more. I welcome ideas for both static
positional queries as well as dynamic relational queries outside of the
chess composition domain.
