Donk bet
Betting into the previous street's aggressor when you are out of position, instead of checking to them. Long considered a beginner's mistake (hence 'donk'), it has a legitimate place on boards that favour the caller's range.
Frequently asked questions
What is a donk bet?
Betting out of position on the flop into the player who raised before it, instead of checking to them. The name is short for donkey — it was long considered a beginner's error.
Is donk betting bad?
Not inherently, though the reputation is partly earned: it forfeits the information a check gives you and often builds a pot you have to play out of position. Done indiscriminately it is a leak.
When is it correct?
On boards that clearly favour the caller's range — low, connected flops where the raiser has fewer strong hands — and with very short stacks where getting money in matters more than position. Solvers do lead these boards, at low frequency and usually small.
