Petra Kulichova's presence in the low post for Frisco Sika Brno since 2006 has helped the club maintain its status as one of the leading teams in Europe.
On Tuesday, the Czech international joined the enemy with ZVVZ USK Prague announcing that the 1.97m center had signed a two-year deal with the team.
The 25-year-old Kulichova is coming off her most difficult campaign with Brno.
She averaged 10.3 points and 5.4 rebounds but injuries limited her to just nine Qualifying Round game appearances in Europe.
Without her in the post-season, Brno managed an impressive run to the Quarter-Finals where they were finally upended by Wisla Can-Pack Krakow.
"Negotiations have dragged on until today," Prague general manager Marek Kucera said.
"With Petra, we have signed a contract for two years."
Kucera had hoped to have Kulichova in the squad before Tuesday.
"The agents have taken a long time, negotiations were not easy, but we eventually agreed, and I think to mutual satisfaction, " Kucera said.
Kulichova is the second big signing for Brno this month.
The club announced last week that Ros Casares talisman Delisha Milton-Jones had joined for 2010-11.
Kulichova's switch will bring back memories of another summer that involved a player that left one club for the other.
After the 2000 season with Prague, Lucie Blahuskova left for Brno.
