1. DGT Centaur
2. Millenium King Competition - M831 (plastic version of King Performance - M830)
3. Millenium Chess Genius Pro 2024 - M815 (there is also a wooden version - M818)
DGT Centaur seems to be very unique in that it weakens itself so that you have a competitive game. Very easy to set up but limited time options. Just turn it on and play.
Millenniums are regular chess computers with many options. One can weaken the engine but I do not know how realistic they play at 1400 level.
There is also Millenium Chess Champion 2.0 (M808) geared towards teaching children.
Centaur and King are almost tournament size. I planned on purchasing the Centaur.
Good luck,
What chess computer do you recommend for a player with a rating of 1400. It's supposed to be a gift
