Introduction
A donk bet is a bet made before the aggressor in the previous street. It is a bet that is often frowned upon on these forums, hence it’s name the “donk” bet. We all know fish love to donk bet, but can you use the donk bet effectively and profitably? I believe you can.
Why is Donk Betting Considered Bad?
Well fish donk bet, and who wants to be a fish???? Fish donk bet for a few reasons;
1. They want to see where they are at
2. They have a strong hand and have no idea how to play it
3. They want to see the next card for cheap
4. They are literally mashing buttons randomly like a crazed monkey.
Obviously none of these are good reasons to do anything.
Probably the main reason not to donk bet is because
people love to c-bet. Even most fish know on some level that if they raise preflop they should bet the flop. This means that check/raising the flop becomes more effective and profitable. The more likely someone is to c-bet the less you would want to donk bet.
Why is Donk Betting Good?
Well for the exact opposite of the reason why it is considered bad. If someone is not going to c-bet often in a certain spot then you should be donk betting more. The decision to donk or not to donk comes down mainly to the villain's propensity to c-bet. This includes his c-bet %, flop texture, relative position, and stack sizes.
Another reason why donk betting can be a good play is that regs on a whole do not know how to deal with donk bets and thus are prone to make more mistakes than they would normally to a check/raise or check/call.

Here is a spot where the BTN has a low c-bet % and the board comes out such that he's going to check this board back unless he has a strong hand. Going for a check/raise in this spot will result in him checking back a lot of the time. So why not donk bet? You are still getting it in vs the same hands that will stack off vs a check/raise and you are preventing the turn coming a 3,5,8,9 or

without him paying to see it. Note: if his c-bet % was 92, then it's a clear check/raise because he's betting this flop a lot more than he should.
Flop texture is another consideration, the board above is a bad one to c-bet because AK does not hit it, and neither does AQ. So this villain who only c-bets 53% of the time is still going to c-bet A

with a lot more of his range than he'll c-bet the flop in the HH example.
You don't have to have the nutty nuts to donk for value. You can donk TP and other such medium strength hands if you think he can call with worse.
But What About Donking as a Bluff?????!?!?!?!?!?!
Well the same concepts apply, if he isn't c-betting frequently in a spot then by all means use the donk bet as a bluff. In this hand we are against the same villain as the last one.

We called preflop because we are ahead of his stealing range, but the reasoning behind the preflop call is unimportant. We flop a bit of equity, we have a gutshot and two overs on a ten high board. This seems like a good board to check/raise, correct? Well villain is probably thinking that too and isn't going to c-bet this board light because it hits our perceived range harder than it hit theirs. So if you check he'll likely check it too, so this in my opinion is a good spot to add some bluffs into your donk betting range.
Note: An important thing to remember when deciding to donk is your own propensity to check/raise, have you check/raised this opponent before? What did you show? If he sees you as a frequent check/raiser then donking is good because he'll likely check behind a lot more, but if you never check/raise he'll likely c-bet a higher % of his range, making a donk less profitable.
Make sure when you are bluffing (and this applies to most bluffing spots) that you have a bit of equity that you can hit on the turn/river. Even so much as a back-door flush draw makes a bluff more +ev, but things like straight draws, over cards, etc makes it so much easier to play on later streets if called.
Multi-Way Pots
One of the most useful times to donk is in multi-way pots, but it's all about relative position. Like everything in multi-way pots, you're going to be more value orientated. When you flop a nutty hand with a fish and a reg in the pot and the choice is between a check/raise or donk/3bet, always consider the fish's position. You want to trap the fish's money as they will pay you off with a wider range than the reg. So if it goes You-Reg-Fish then you would be better check/raising as the reg can c-bet, the fish can call, allowing you to shovel more money into the pot, however if it's You-Fish-Reg, consider donk/3betting as you can get the fish to call your bet before the reg has the opportunity to raise. It's all about relative position, which is one of the funnest concepts in poker, you can bluff vs one opponent and value bet another in the same street of poker, which has endless implications.
Remember the more people in the hand the less likely someone is to c-bet light and therefore you should be donking more frequently in these spots (and obviously more for value).
Multi-Street Planning
Obviously I've talked a lot about flop play, but the concepts are still the same on the turn and river. If they aren't going to double barrel often, then c/c, donk line is perfectly valid, same on the river. This is where good hand reading becomes important, you are trying to manipulate their range to make you the most money. How? Well you've got to try these things out for yourself, that's the fun part

Conclusion
I hope to get some discussion over donking in general. I know a lot of people hate it, I for one, like donking, if used properly and with good reasoning behind it. The games are still very c-bet happy so it should have limited application, but adding it to your game can make you a more tricky opponent and be able to make the most of profitable situations however they present themselves. Remember to always be looking for the best play at anytime, no matter how weird or unorthodox it could be.
