Chess Openings Wizard Express has every tool you need to design your openings and defenses.
Want to use the strongest engines? COW comes with some of the strongest including Stockfish 16.1, and you can swap in the engine you like best as new ones come out.
Want to make your diagram look like Chess Life or look like an old Informant? The diagram options have that.
Want to purchase complete repertoires ready to expand and train yourself? We have those.
Want to import PGN games that you played on Lichess or Chess.com or that you pulled from a game database like ChessBase? Done.
Do you want to instantly bring in your last Lichess game to see how it compared to your repertoire? One click is all it takes (after you set it up of course).
Paste in PGN and FEN from the clipboard? Of course.
Export graphic diagrams in PNG, JPG, and BMP for your web pages and student handouts? Done.
Create endgame and tactics studies? All the functions you need to set them up are in there.
Back up your work to a free Dropbox or Google Drive account so that you will never lose it? We recommend using this integration. It's also used to move your openings to your iPhone or Android phone or tablet so that you can study on the go.
Limited to 150TB per database? (If you know what a terabyte is, you know that is hardly a limit. We're poking fun at other chess software and their arbitrary file size limitations.)
The final super duper thing that sets COW apart from every chess app: You get support directly from the programmer. (Can you imagine being able to ask questions of the actual programmer of any other app you use? With Chess Openings Wizard you get email answers from me (Mike) who codes your app.)
