中间位河牌湿润面全下（MP River Jam Wet）
Refers to the action of going all-in from the middle position MP on a wet river board.
The term consists of three elements: MP (Middle Position), River (the fifth community card), and Jam (all-in). Wet describes a board texture where clear drawing possibilities exist, such as completed flush or straight draws. This term is not a standard poker term but a descriptive combination in specific scenarios. In practice, if a player jams all-in from MP on a wet river, it usually means they hold a made hand (e.g., top pair or better) or a completed draw, aiming for value or bluff. Since the river is wet, opponents may hold marginal hands or missed draws, and the all-in applies maximum pressure. However, this term lacks a widely accepted definition and needs to be understood in the context of specific hand histories.
