chess king

can anyone tell me if its worth getting chess king 3.iv already got chessmasterGE and ad great fun playing and learning the game.

I haven't seen the new interface that's shipping later this month, but wouldn't you want to wait for that?  I have the old version and it's fun to use and easy to figure out.  Progressively more difficult puzzles and "handicap" games.  Decent database.  Import/export PGN files.  Analyze with Houdini.  Probably more a fun training tool than anything.  I got mine bundled with a 6pack of other tactics, opening, endgame, and strategy/pawn structure programs.  Old school Soviet repetition method with thousands of examples.  It's a tossup whether I like the main ChessKing or the 6pack more.  Good value, easy to use; a little crude here and there, but nothing to drive you crazy.  I might upgrade but the existing interface works well enough that I'll wait for details, maybe a review or two.

I got the promo email and, sorry to hijack the thread slightly, has anyone tried the chess ok software with wine on Linux? It certainly looks worth a punt, but I'm concerned about how it will function.

I've got CT Art 3 on Windows and I remember that being a little rough, but I'd like to move all my chess stuff to Linux in the future and I'm interested in CK3.

Is Chess King a UCI interface ? I assume it is, but can't find that stated in their ads.  A related issue is whether the Houdini 3 engine , that accompanies it, can be used with other UCI interfaces ?
