When Donk Betting Makes Sense: OOP Leading Spots
Short Answer
Donk betting makes sense when the current card clearly improves the OOP range and weakens IP's previous betting advantage. Common examples include turns that complete low straights, flushes, or pair cards favoring the defender.
Why Leading Can Work
If OOP always checks to IP, IP controls many turn and river nodes for free. When a card strongly favors OOP's calling range, leading lets OOP value bet immediately and pressure IP's medium-strength hands.
Good Boards
Low straight-completing cards, front-door flush completions, low pair cards, and two-pair cards more common for the defender can create leads. The key is not “I improved,” but “my range improved.”
Range Structure
A donk range still needs balance. Value includes nuts and strong value. Bluffs should block IP's strong continues or retain equity. Leading only strong hands weakens checks; leading only weak hands gets called.
