View Full Version : Simulators do not make sense or I am going NUTS 50/100 LIMIT


10-19-2005, 10:54 PM
I am playing a 50 / 100 LIMIT game so this hand really needss help for me. I ended up losing this hand by the way.

Ok here is the flop... 5s6s7s and i have Qs9d and opponent has 57. The simulator shows that my opponent will win most of the time, but that doesn't make sense... My outs are 9 spades and 4 8s(for a straight) which total to be 13 outs, and 13 x 4 = 52 percent of ME winning, why does the simulator say that the opponent will win? Any thoughts on this guys? Am i going nuts?

Does the limit really matter here?

how did you calculate that 43? I thought it was 52... 13 outs x 4 = 52 percent

This is correct. It is only 43% in 30/60

that times 4 bs is a pretty terrible estimate once you get above 10 outs

Welcome to the forum rookie. /images/graemlins/smile.gif

You have 9 spades, 3 8s (you've already counted the 8s), and random runner two pairs as outs. However, he has a 4 out redraw no matter which of these you catch, which is enough to give him the advantage.

good luck.

To summarize what others have said, as well as trying to play to your theories...

You have 12 outs, not 13.

12 x 4 = 48%.

However, if you get there on one of the streets, your opponent can get there on the other street. i.e. turn a flush, river a fullhouse. He has 4 outs.

4 x 4/2 (because only one street) = 8% that he redraws.

8% of the 48% is about 4%. So, you actually win 48% - 4% of the time, or about 44% of the time.

I hope that makes sense.

You arent drawing to the nuts while he is so if he catches on the turn you have 0 outs.

So ~8% of the time you are drawing dead on the river.

Your one card straight draw isnt that flash either because he has additional outs he can catch a 9.

He has outs to a house which means even though you're going to be ahead assuming he doesn't improve like 52% of the time he can still improve.

I don't understand this multiplying by 4 business. Is it some kind of rough rule of thumb?

The confusion you are having is that you are trying to compute the probability of making the hand that you are drawing to. That is not the same thing as your probability of winning the hand - which is what the simulator gives you.

As everyone has already pointed out the probability of you winning the hand is less than the probability of hitting your draw, because you opponent can improve to a full house even if you make your draw.

You are using a rule of thumb to get your 52%. It is just an estimate. First, not figuring redraws, with 13 outs you have:

1 - (32/45 * 31/44) =~49% of hitting.

He will boat up
1- (41/45 * 40/44) =~ 17%, but you cannot just subtract that from the 49% because then he only has one card to hit if you make your hand, which is less than 10%. Basicly, the easy way to do these is to plug them into pokerstove which will iterate over all possible boards and show you to be a ~9:11 dog, but you definitely have odds to continue there.

Is your 6th post better than your last 5?

I feel thats as good an answer as this post deserves.

Do 50/100 players really ask these questions? Maybe it's time I moved up.

I guess no one forgot when answered this post to count a chance of 89 or 34 come on turn and river to split this pot? /images/graemlins/smile.gif

Let us suppose we see our opponents hole cards and the flop. We determine that we have n outs to a hand that is better than his. The chance that those outs don't fall on the turn and on the river is

[(45 - n) * (44 - n)] / (45 * 44).

Therefore the chance that one of those outs comes by the river is

1 - [(45 - n) * (44 - n)] / (45 *44) = (89n - n^2) / (45 * 44).

To convert this to a percentage, multiply by 100. We get that the percent chance we hit by the river is

100 * (89n - n^2) / (45 * 44) = 5 * (89n - n^2) / 99 = n[445 - 5n] / 99.

For small n, (445 - 5n) / 99 ~ 4.217

Thus the approximate percent chance we hit by the river is 4.217n. But just like the "rule of 72" we simplify this by saying that the approximate percent chance we hit by the river is 4n.

The derivation that the rule on the turn is 2n is left to the reader as an exercise.
