Zompist Bboard Again

What is the correct way to pronounce the name "Tzuke"? AFAICS It violates at least one, and possibly two, orthographic rules.

It appears that our two most active Polish members stopped coming here a while ago (Pole/anxi since March last year after another absence, and diego since October). Maybe you could try asking your question at the Polish conlanging forum? (Presumably in the Polszczyzna section.) The forum is very slow, but it still seems to be getting a couple posts every two or three days.
