Default Which AAxx hands to raise out of the blinds?

Average low limit live game with 20 people seeing the flop.

Which AAxx hands have enough of an equity edge to raise out of the blinds for value? I'm assuming suitedness matters a lot here...

i wouldn't think about equity so much as which hands are more likely to make playable hands on the flop.

I don't think that there would be a significant difference between the two.

[/ QUOTE ]Hi Niediam - You tell me where to draw the line.

Following are simulated win totals for 211 double ace hands.
d means double suited
s means two cards in same suit including an ace
s- means two cards in same suit not including an ace
s白 means three cards in same suit
n means rainbow (four different suits)

For all s hands shown, the ace is the same suit as the lowest card (but it would not make much difference if the ace were the same suit as the middle card).

Results are all for 10,000 runs against eight non-folding random hands. (In other words, a different random hand was simulated as dealt to each of eight different table positions 10,000 times).

The first column is the hand,
the second column is high only win sub-total,
the third column is low only win sub-total,
the fourth column is scoop sub-total,
the fifth column is total of second, third and fourth columns.

For the second and third columns each solo win is counted as 0.5, each a two way tie is counted as 0.25, each three way tie is counted as 1/6, and each four way tie is counted as 0.125. All values are rounded off to the nearest whole number. In the case of exact halves, the numbers are rounded to the nearest even number.

If the simulations were re-run, it is expected that the totals would change somewhat, but not substantially. 1,111 is average for a nine handed 10,000 run simulation.

In a real game, obviously all eight opponents who are dealt hands will not continue to the showdown. How many opponents do continue to the showdown depends on the actual hands dealt, the flop cards, the turn card, the river card, the betting, and how the opponents interact. If the simulations were run against a different number of opponents, the relative order would change somewhat. If the simulations were run against different groups or mixtures of opponent tendencies, the relative order would change even more.

Note that the worst starting hand on this list, AA89n, would not be the worst hand on a one-on-one list of the same hands. Also note that if you raise before the flop against Chester Milktoast with AA89n, you have a better chance of stealing the pot, or winning after the flop with a continuation bet than if you raise before the flop with an even better hand against Bulldog Doubter.

You tell me where to draw the line.

I'm with antistuff. Without straight/flush or decent low potential, a lot of the hands will be hard to play OOP in a multi-way pot, even if they are +EV in a no fold'em simulation.

Default Re: Which AAxx hands to raise out of the blinds?

Thanks Buzz, this is really good stuff. I have a couple of questions, though:

1. In a loose game, there are always players who still will play reasonable hands. With 8 people seeing the flop, one could assume that there are no aces left in the deck. How would AAxx perform in such case?

2. I am looking at the "high only" numbers and I am somewhat surprised to see that AAKKd (best omaha high hand) is winning less than a hand like AAJ9d. Is that due to the normal fluctuations with the simulation, or is that really the case?

By the way, what simulation software do you use?

[/ QUOTE ]Hi Tilt_Monkey - I do think that's sometimes a valid assumption, but it depends on your opponents as a group. Even with 8 people seeing the flop I don't think you can necessarily assume there are no aces left in the deck. At least five of your opponents are playing ace-less starting hands. Why not six or seven?

But at any rate, anyone seeing the flop naturally wants to continue and is looking for reasons to continue. Exactly what a solid player needs in order to continue depends on the particular cards of the flop, but when 8 people see the flop there's a pretty good chance someone will find a decent reason to continue for high, probably needing only one card to make a straight or better.

[ QUOTE ]
How would AAxx perform in such case?

[/ QUOTE ]Generally poorly.

If the flop is paired, solid players will be continuing with sets or flopped full houses. Your opponents will have 28 cards between themselves. If you don't have a card the same rank as the board pair, there's a high probability (~86%) an opponent does.
The math: <ul type="square">1-C(43,28)/C(45,28)=0.8626[/list]And in addition, someone might have a pair matching the odd card on the flop. It's unlikely you'll see an ace on the turn or river (p=~8.8%).
Bottom line: you have a negative e.v. for playing bare aces when the flop is paired.

When seven opponents see the flop and the flop is not paired, opponents will continue with flush draws, flushes, straight draws, straights, sets, and two pairs. All of these are generally better than a pair of aces. With a pair of aces, you'll be drawing for an ace to make trip aces and even when that happens for you, an opponent can end up with a straight or better.

Thus with eight of you seeing the flop, unless you catch an ace on the flop or unless at least one other two-card comgination in your hand is working for you, you should probably fold.

[/ QUOTE ]It isn't.
AAKKd.....794+0+1186=1980
AA9Jd.....814+0+747=1561

AAKKd is the best high-only hand, as simulated, with a pair of aces.

But interestingly, 10,000 deals may not be enough! When I did the simulations for the series of post-flop articles for the 2+2 on-line magazine, I used at least 100,000 deal simulations. I'll run both of those again at 10,000 deals, just to see. I expect the results to be similar, but a little bit different. Here goes:
AAKKd.....772+0+1149=1921
AA9Jd.....757+0+764=1521
As you can see, the results are a bit different.

I'll run them both at 100,000 deals for Omaha-8. Here goes:
AAKKd.....7957+0+12027=19984
AA9Jd.....7755+0+7648=15403
As you can see, the results are about ten times greater than for 10,000 runs. Presumably they're also better values.

Simulated for high only (also nine handed)
AAKKd.....19+2712=2731
AA9Jd.....65+2196=2261
first column is hand,
second column is high splits halved,
third column is scoops,
fourth column is total.

AAKKd is a substantially better hand in Omaha-high than Omaha-8 because there are no splits with low.

[/ QUOTE ]For these I used Wilson software.
