One of my favorite underplayed hands is K8 offsuit. It’s not a hand most players get excited about, but I’ve had some solid results with it — especially in late position or when facing weak limps. It can hit top pair with a decent kicker, and when played carefully, it can apply pressure against opponents who underestimate it.
It’s definitely not a hand I go crazy with, but it’s become one of those underrated tools in my range that catches people off guard. Sometimes the “ugly” hands can surprise you!
