Okay, this Millennium electronic chess board is seriously smart. The AI engine adapts to your skill level - it scales from 350 all the way up to 2200 ELO, so whether you're just starting or you're pretty advanced, it'll give you a good game. It's got this massive training library with over 20,000 openings, and the coaching system is supposed to help you improve three times faster than studying on your own. The board itself is German engineered - a 10.6\ sensor board that registers every move instantly and accurately. The pieces are tournament weight and magnetic, so they stay put. There's a protective felt, a nice storage bag, and a clear LCD that shows analysis and positions. It's pretty portable too - about the size of an A4 sheet and only 2 pounds, so you can take it with you. Runs on battery or AC power. You can adjust the time controls from super fast bullet chess to classical, and it stores unlimited games so you can review your performance. Over 50,000 players use this thing globally. Setup takes about 60 seconds with the illustrated guide. If you're serious about improving your chess or just want a reliable opponent that's always available, this is a top choice.
