Full explanation — Thin Value
Thin value describes a value bet made with a hand whose edge over the opponent\u2019s likely calling range is small, not the huge advantage of a typical value bet. It requires a precise read on what the opponent will call with, since betting slightly too much turns the situation into a pure bluff instead. Strong professional players routinely "bet thin" in marginal spots, and over thousands of hands this consistent extra value adds up to a substantial edge in winnings.
