An interesting way indeed of introducing Passing, and tournaments certainly speak for its viability in play.
The emphasis on capture and exchange as the mechanism reminds me of the newer version of Cetina's Universal Chess; I must immediately wonder about combining the two :)
Btw, do you have more info about the inventor? He may be well‐known for you, but I (and I imagine many of us non‐Russians) have never heard of him, and the only V. A. Kupchenko the web immediately turns up is apparently a Physicist (though I of course can't rule out this being the same one). In particular, it'd be nice to be able to credit him by name, rather than only by his initials
