Can you use batteries or are you limited by ac. If so , is it 110-220?

The King Competition requires AC power (110-220) or Power from Chess Volt Accessory.

Chess volt accessory on your website the list of compatible models m831 is not listed. is that correct?

The Chess Volt IS compatible with the King Competition (M831).

It says it has auto sensing pieces and then it says you have to pressure sensing technology. Which is it?

I'm sorry; The title description is incorrect; it is a pressure sensitive board. In essence, this is the same thing as the King Performance (M830) with a more modern look.

This does come with a power cord, right?

Yes, it comes with a power cord / power supply.
