J♦9♦ SB vs BTN, turn on Q♣ 8♦ 4♠ 2♠, 75 bb

Best play: Overbet 120% pot

Why

Turn, board Q‑8‑4‑2. As the SB out of position versus a capped BTN, hero has jack-high with a gutshot to the ten plus a backdoor diamond draw, no made hand. On this dry queen-high board the BTN range is mostly weak, so overbetting as a polarized lead applies maximum pressure on the many missed hands while keeping equity to improve when called.

Key idea

On a dry turn out of position, an overbet lead with a gutshot and backdoors leverages fold equity now plus outs to improve later.

Common mistake

Checking the gutshot passively and surrendering the dead pot a capped range will fold most of the time.
