If there are 2 hearts on the flop, what are the odds villain has 2 hearts in his hand, given (1) I have two hearts; and (2) I have no hearts.

We all know having hearts decreases the likelihood villain has hearts, but I'm curious what percent difference it makes.

I want to use this tool, calculate the card blocking, how many of them, I don't know what tools are there

Propokertools is an amazing tool for this feature. Tough to answer your question given rfi range/calling range/3bet range will impact outputs but the tool lets you ask questions such as "how often player_1 flops 4 to a flush" etc.


super rough example

Blocker stuff is way over rated.

Not sure why this guy has come in recently spewing nonsense.

Simplified view of button vs BB

With hearts for hero.



Without hearts for hero.



24% vs 34%

So the villain is almost 30% less likely to have a four flush if we have a four flush then if we don't.


To finish this off.

How am I spewing nonsense? Blockers and back door draws are over rated concepts.

For holdem, perhaps. They obviously matter more in PLO especially on the river where bets are going to polarized. And when equities run close, that extra 5% from a bdfd can make all the difference.

To anyone who thinks blockers aren't relevant in any form of poker (holdem or plo), you're wrong. Dive into a solver, run some equities and it may open your eyes a bit.

In short, back door draws give us better future options (playability, bluffs). They help construct multi street ranges, not just one street. They also can decrease opponents equity as well as increase ours. Blocker also help with hand reading.

Yell me you dont play enough PLO without telling me.

They are often where you will squeeze out the most EV.

If you are jusy playing your PLO hands face up for the nuts you are playing PLO wrong.

Blockers and BD considerations MUST be included in PLO decision making if you are a Player who 'studies' the game. 4-12% swings in EV can and will have a long term affect on potential results. Ignoring these 'small' details is fine, but it makes a Player more a 'card' Player than a 'poker' Player IMO .. and there's nothing wrong with that.

The perfect example is when you hold the Ace of Flush while in position. Yes, this is a Blocker that will allow you to more comfortably Bluff at a pot and holds just as much, if not more, value than holding two random flush cards that may not win at Showdown.

Might I expand the OP and include 'which' flush cards you may hold. Both rank and suit matter as specific cards may block both the flush and straight cards needed to fill out an opponent's best finish.

Are Blockers a fail safe? Certainly not, but anything you can use to help swing a decision one way or the other with legitimate EV/Equity implications should not be ignored .. and based on the data above may be much larger than most might think. GL



PS .. IMO the PokerGo subscription fee for 2024 is =EV just based on the stream session where Chance Kornuth is in the booth. That amount of information would cost you a lot more via a sub fee to a coaching site. Also, the speed at which he recognizes a spot and starts to talk about it is lightning .. which lends itself to not knowing why he is one of the slower Players I see at times.

Obviously if u hold some of the suit on board the other guy is less likely to have that suit. That is not a ground breaking find, it should be common sense. I am just saying people are spending time worrying about blockers and calling because they have backdoor draws and they are over rated. The idea is to keep people confused so they have to buy programs and coaches and what ever else they sell. What concept will they think up next year to try to get your money by making the game sounds more confusing then it is?

Tell me I play tons of plo and don't play hardly any hold em for the last 8 years. Also come join would love to have u at the table.

Sure. Dm me

Dm u what?

You're certainly not the sharpest tool in the box. It means direct message me. I will join your game or you mine.

Where do u play? What country u in?

Roughly: HU, 2 hearts on the flop. Villain has 2 hearts 21% if you don't have a heart, 18% if you have one heart, 15% if you have 2 hearts

No response?

Dm him if you know what that means
