An Update in English is planned for the 1st quarter of 2025! Stay tuned.
Czech speaks for itself.
Nice Czechmate against a NM. The variation with 4.f3 is relatively rare, but some people just play their fianchetto Pirc fuss. Due to all the transpositions with Be3, Nge2, a3, g4, Qd2 in any order, the theory here is enormous, I usually play by ear. The computer refutes every move for both sides at will. This was +2 in the opening e.g.
“Who's afraid of the Plusequal?” Jonathan Rowson, Chess for Zebras. Today, in the age of self-confident engines, this can justifiably be extended to dynamic positions that are +/-.
However, this cool 3+2 game against a NM with FIDE 2251, Blitz 2400, Bullet 2613 was fun.
The Czech Pirc/Defense is a way of playing against e4.
Plusequal += was a term Rowson had coined. As Black you don't have to fear dynamic += lines. And so is +/- nowadays, the engines have just enhanced their winning probabilties for the same.
First review: “Obscure Jokes” - that made my day! 😃
"I'm speeding through this course and loving it. The progression of lines in the chapters is very logical and organized well in the chapters. The author has included great annotations, obscure jokes, and many links to reference games throughout. The Rebellious Czech Defense is my cup of tea."
Latest review:
.. This is the ultimate course on the opening, rendering all previous sources obsolete. ...
... Markus Müller has chess culture. I’m a classical philologist and I love my classics: Cicero, Vergil, Nimzowitsch, Rowson... ! :-D It’s just refreshing to read commentary that is intelligent and enriched with references to the classics of chess literature – especially in this age of super-engines and databases. ...

I have modernized the Czech Defense in respect to every standard. A chessable course in German will be launched in a couple of days. >600 variations, 25h of video footage...
Here's a typical motif, sometimes you have this ...d5 counter at hand.
