Happy New Year to the RIO community !
Here's a script for an easier RNG (it's always updating every at the tip of your mouse pointer) :
> install Autohotkey first, at

SetBatchLines, -1
lastNumTick := A_TickCount
Random, randNum, 1, 100
SetTimer, UpdateRandomNumber, 1

If (ATickCount > lastNumTick+3000) {
Random, randNum, 1, 100
lastNumTick := A
ToolTip, %randNum%


(can't remember where exactly I found it; probably on the Autohotkey site.)

I relocated to Spain, lol.
I did some of these home games too, but otherwise, I played in legal local clubs (outside casinos); I think they're not allowed to do cash games though.

Thanks for sharing your DB analysis, great work ! (from a fellow Belgian)

150 bucks is a steal.
I'm about 50 % into it and skimmed throught the rest.
Very thorough and well organized course.
Plus you have solid homework at the end of most videos to make you think further.
You can't go wrong and should recoup the price very soon.

Nice addition !
I snap bought it; no need to check if it's a quality content, as I'm sure it's up to par with his other videos.
I'm sure to get the price back easily on a few dozens MTTs, as I have some serious leaks to plug and some concepts that I don't apply well enough.

Thanks !

of course there is !

Cheap and fast to develop, and very useful, as printing forum pages for reference is a real PITA.

I just took a quick look at lecture notes "8. Decision Making", presented by Matt Hawrilenko.

It looks basically like a more graphical version of a previous course he gave some years ago.

I covers some fundamentals of GT like the AKQ game (presented here by Sauce123), the basic GT equilibrium formulas at the river and the basics of exploitative play.

I suck at math too.
I didn't even realize that the number in the A column (ratio of bluffs to value bets) is even easier and straightforward to use :

  1. 40 value combos and a 3/4 pot bet
  2. 40 X 43 % = 17 bluff combos

done :)

March 10, 2015 | 5:27 p.m.

I also suggest you read :

Poker Math That Matters by Qtip

which will be a great help in getting familiar with the basic math and combo counting; he demonstrates a lot of mental math shortcuts to quickly use in game.

March 10, 2015 | 4:57 p.m.


Do you think there is any way that I can use this quickly ingame?

this post answers exactly what you need :

GTO simplified (OTR)

I have the table memorized and using it in game is fairly "easy", with a little habit.

Knowing you have 40 value combos you can easily derive the number of bluffs :

  1. if you bet 3/4 pot you know from the table the bluff ratio is 30 %
  2. 30 % bluff combos means 70 % value combos
  3. divide 40 by 70 % to get the total number of combos in range : 57
  4. number of bluff combos = 57 - 40 = 17

Obviously, you should get familiar with some simple mental math, but using the table, you get to do the same operations repeatedly and will rapidly become proficient at it.

Here we have to divide 40 by 70 % which looks difficult until you remember that 7 X 6 = 42;
so 40 / 70 % is a "bit less than" 60 so you may get a quick answer of 57 (or even 56 or 58, which won't influence too much the result, imo).

Of course, you must count your value combos acurately in the first place ;-)

check the thread on 2+2 :

Applications of No-Limit Hold 'em Review and Discussion

If I remember correctly, he admitted his preflop ranges weren't the "best".

March 7, 2015 | 9:15 a.m.

So here, if we bet a 1:4 bluff to value ratio,
- V. should always fold IF we bet bigger than 1/4 Pot (EV call always < 0)
- V. should always call IF we bet less than 1/4 Pot (EV call always > 0)
- at exactly 1/4 Pot, Villain should call 80 % to make our bluffs indifferent to betting or checking (EV call always 0)

a mistake here in my first reply : the GTO bet sizing is 1/3 Pot for a 1:4 bluff to value ratio range.
Also, the Optimal Calling Frequency is 75%, not 80 %.

I should've refer to my own GTO simplified (OTR), lol.

Feb. 17, 2015 | 11:53 a.m.

Hey Steve, thanks for taking the time to answer.

You did indeed a good job in the video explaining your point.

Assume villain should call 80% vs a 1/4 pot bet, and fold to a larger one

That is not a valid assumption : if you bet a larger bet, let's say Pot and your bet is balanced like in your example, GTO opponent will call optimally (50%) to make your bluffs indifferent (to folding or calling). However, because you are balanced, his calling frequency doesn't change your expectation, which is always 1 (Pot).

Regarding your example : the problem in your reasoning is your adjusted strategy is only valid if the opponent doesn't counter adjust. But a GTO solution implies you cannot unilaterally increase your expectation by changing your strategy, knowing that your strategy is exposed or opponent is clairvoyant (Nemesis) and opponent WILL adjust.

So against your strategy, the Nemesis will adjust by never calling your 1/4 bets and by calling optimally your Pot sized bets. Your EV will now be decreased (< 1 Pot) instead of increased.
If you bet a 1:4 bluff to value ratio range, the GTO (maximally exploitative) bet size is 1/3 Pot; your EV is 1 P and you cannot increase that EV against a nemesis.

I you are right, you should be able to find a GTO solution for your example, playing against a clairvoyant opponent that will continually adjust to your known strategy.

Feb. 17, 2015 | 11:40 a.m.

when you don't have enough bluffs, Villain should fold to any size.

This must be wrong because there is a GTO sizing for each bluff:value ratio.
Meaning there is an GT optimal solution which maximize the EV of the strategy and you try to demonstrate [27:08] that there is a strategy that yields a better EV, which is not possible, otw the GTO solution would not have its EV maximized and thus wouldn't be optimal.

Using the same example, in the thread you reference, you also state :

Say we get to the river in nuts/air vs bluffcatcher with 4 nut combos
and 1 bluff combo (ie we have very few bluff combos). No matter what
betsize we choose, our opponent should always fold.

for that bluff to value ratio, betting 1/3 Pot is optimal and yields 1 P in EV AND Villain must call 75 % for our bluffs to be indifferent to checking of betting.

Also, "you don't have enough bluff" is vague, completely imprecise. You should state : "you don't have enough bluffs with regards to this bet size" ("... which makes you imbalanced towards value").

So here, if we bet a 1:4 bluff to value ratio,
- V. should always fold IF we bet bigger than 1/3 Pot (EV call always < 0)
- V. should always call IF we bet less than 1/3 Pot (EV call always > 0)
- at exactly 1/4 Pot, Villain should call 75 % to make our bluffs indifferent to betting or checking (EV call always 0)
