Why the button is best

The button rotates clockwise each hand. After the flop, the button acts last and sees everyone else's action first. That informational edge is enormous over thousands of hands.

Preflop, under the gun (left of the big blind) acts first — hardest seat. Postflop, small blind acts first if still in.
