Full explanation — Cutoff (CO)
The Cutoff (CO) is the position situated directly to the right of the Button. It is widely recognized as the second-strongest position in poker due to its late-acting nature. From the Cutoff, a player often gets to act last if the Button folds, which occurs frequently, giving them a significant positional advantage. Skilled players strategically widen their opening range from the CO, looking to isolate the blinds, steal pots, and play against fewer opponents from a strong position, making it a highly profitable spot for aggressive play.
