If you use your BlackBerry for business, the thought may have occurred to you that the strategies you need to succeed in the competitive world of work have a good bit in common with chess.

Not only the strategy, but the degree of mental intuitiveness and alertness involved. I even know someone who regards his twice-weekly chess matches as kind of a mental tune-up for the business challenges he regularly faces.

So why not combine an exercise in mental acuity with technology- and play  chess on your  Blackberry?

Magmic Games' Medieval Kings Chess II is one of the more realistic and interesting chess software products. Requires BlackBerry OS 3.7 above, as well as at least 219 kb of storage room.

This downloadable game costs $9.95, but is available to Club Handango members for $8.96. I've placed a link to the Handango.com page for Medieval Kings directly below this post.

Oh, and if you find yourself a little rusty about chess, here's a link to the free encyclopedia Wikipedia's article on this most cerebral board game.
