Full explanation — Donk Bet
A donk bet is an initial bet made by a player out of position, who was not the preflop raiser, directly into the preflop aggressor on the flop. Historically considered a sign of weakness or a mistake, modern poker strategy recognizes its utility on certain board textures. It can be a powerful play to deny equity to opponents with marginal holdings or to build a pot with stronger, disguised hands, especially on boards that heavily favor the donk bettor's range.
