donk-bet

A donk-bet (often just "donk") is when the OOP player leads into a new street, breaking the convention that "the preflop last-raiser bets first postflop." Older poker theory treated the donk as a sign of a weak player (the term comes from "donkey"), but modern GTO solutions show some boards have a legitimate donking frequency.

Detailed Explanation

In traditional theory the donk was wrong because:

• It breaks the standard cbet cadence and gives the opponent free information
• An unbalanced donk range is easy to exploit by raising

But modern solvers show donking frequencies in certain situations:

• Boards that favor the caller (e.g. BB calling BTN, flop 9-8-7r): BB's range has dense connectors and two-pair combos with range advantage over BTN
• Turn structures that shift the advantage to the caller (e.g. opponent's cbet got called, then a key card on the turn): the caller can lead to express the newly formed strength
• Multi-way pots: donk exploits the high-frequency cbet habit that's standard in heads-up

A donk range must be balanced: pure-strength donks are easily folded against; pure-bluff donks get raised. A healthy donk range pairs value with semi-bluffs.

Common Use Cases

• BB defending vs BTN on low connected boards: donk frequency rises
• 3bet pots OOP: the 3bet caller's donk has GTO frequency on some boards
• Turn structure changes: flop favored one side, turn flips it → the other side donks
• Reading an opponent with extreme cbet frequency: donk gets ahead of their pressure
