That is very embarrassing. Leave out one '8' and the whole thing goes to pot. The problem was caused by me carelessly typing and 'omaha' where I actually meant 'omaha8' Fixed now.

On the main ev calculator page at:

http://www.evplusplus.com/poker_tool...ty_calculator/

there is a link under the heading "Quick Start Guide" that points to a code 404 page:

The "examples" link points to:

http://www.evplusplus.com/poker_tool...ator/examples/

Is this actually supposed to point to:

http://www.evplusplus.com/poker_tool...docs/examples/

?

yes it is ty!

This looks very interesting, but if i click the link to the calculator (http://www.evplusplus.com/poker_tool...ty_calculator/) I can only choose Holdem:



I'm using Firefox 3.6 and it won't work in safe mode, too. Any idea?
It works fine with Opera though.

Unfortunately right now the calculator (and variance simulator) only works with Javascript enabled so you would have to set noscript to allow javascript on that page.

I realize that having your website not degrade gracefully if the user doesn't have javascript is poor form, so I will put a non-javascript version on my to-do list.

I have a question about hand ranges. Using the hand range tool at:

http://www.evplusplus.com/poker_tools/hand_ranges/

I can select, for example in Hold'Em, any two paint cards by specifying any two "big" cards (the "B" card type) excluding Aces, by using:

BB!A

This then produces a list of all C(12,2) = 66 combinations I was hoping to find.

But when I try to choose any two Broadway cards, by using:

BB|T

then instead of getting C(20,2) = 190 combinations, I get 318 combinations. First I would like to point out that the first 187 combinations in the list are from the set I was expecting, and the three other combinations (all three are pairs of tens) are included as well farther down. But it looks like I also get all Tx hands as well. What am I doing wrong? (see footnote)

By the way, it would be way cool if there were two additional card types:

P = any paint card = {K, Q, J}

and

D = any broadway card = {A, K, Q, J, T}.



footnote: Also, it looks like the 2 is missing and so shows up as a double underscore character. For example, when I enter the range A*c for any ace along with any club, all of the hands that should show the 2 instead show this: __

The | is the OR operator, so you are selecting all hands that contain two big cards (BB) OR any hand containing a T. To get all broadway hands you would have to BB | BT |TT. So hands with two big cards + hands with a Big card and a T plus the pair of TT's. BB|BT|TT

consider it done.

ups. I know what is causing this and will correct it. ty.

Broadway R :: AKQJT &
Face F :: KQJ

cards should now be working.

Thanks for adding those two frequently used options (F & R).

I have a question about 7-stud Hi/Lo. I ran a simulation on ProPokerTools and on ev++ and got different results. But the overall equity difference was not that great, so I wonder if it was due to the method of calculating equity in split pots or in figuring out scoops, or what. At any rate, PPT has the 7c6c2c7d winning low with a probability of 177958/600000 = .2966. Whereas ev++ has a much different answer, showing that same hand winning low with a probability of .1841 instead.

Anyway, here are the two simulations (maybe I just did them wrong):

NOTE: I had to fix the table produced by PPT because the pipe character (which is "|") that is required in 7-stud hands was generating an unnecessary column on the bottom half of the table.

My pleasure.

Was a small relic of the 2c = __ problem you discovered earlier

Updated. Thanks!

Actually, the ev++ calculator result is even closer than that to the PPT result. You overlooked that the 3s is a dead card:

3	**Jd6h	1 / 0.0%	24.10	0.02	8.86	0.05	13.03	22.35

Again, for comparison:



I appreciate the ability to do stud simulations without specifying specific up-cards, as required by PPT. I also *really* like the ability to simulate how a hand will do against more than just four opponents (another limitation of PPT).

Great work all around!

I will continue testing and report any further anomalies.

Oh nice. didn't notice the dead card in there!

I'm not seeing anything different happen when I check the "street-by-street" option. I just get the usual showdown results, which are not broken down by PF vs. flop vs. turn as in this image:




EDIT: My mistake. You have to specify the board cards for the "street-by-street" equity to be shown, LDO!

hehe yep, board cards are required

your tool is awesome, thank you!

My pleasure cardcore thanks for letting me know you like it

Very nice Neko! Now I have no excuse to put off learning new games.

I see on your site you also offer some coding/scripting services. Are you doing that personally? I have something I'm interested in and it would be much easier for a fellow poker player to understand.

Hey WillyT, Thanks! We used to play in UB's old 5/10-30/60 games together right? (I was mellow_gold)

Yes for right now I am doing all the coding myself. I am currently working a short contract that is killing a lot of my time but PM me, or contact me through www.evplusplus.com/contact/ if you want to discuss your idea.

Very nice tool. Nice work OP!

Awesome !

Thanks guys

I'm having some trouble with the hand range tool at:

http://www.evplusplus.com/poker_tools/hand_ranges/

Specifically, I was trying to examine the O8 range of all double-suited pairs of Ks that do not contain an Ace. I tried this expression

KK**!A{ds}

and got strange results, with that pesky __ character showing up again. The "link to this range" field produces:

http://www.evplusplus.com/poker_tool...ertools&page=1

I'm not sure what is happening, but I guess I used the wrong specification for what I wanted.

For comparison, here is the results for ALL double-suited pairs of Ks with

KK**{ds}

which seems to produce the expected results at:

http://www.evplusplus.com/poker_tool...ertools&page=1

except that all of the hands containing the 2 appear to be missing?

Certainly when I go for any pair of Ks with:

KK**

which you can see at:

http://www.evplusplus.com/poker_tool...ertools&page=1

the 2 appears again as __.

Oh My I guess I haven't killed that bug completely yet. I will look into that.


KK**!A{ds}

The way you have it written, the {ds} filter is only applied to the A (equivalent to A***) selection so the above expression will select all hands with kings in them (KK**) and remove all hands that have a double suited A. What you want is KK**{ds}!A -which selects all double suited kings and then removes all hands with A's.

Alternatively you can specify global filters using a : as a separator at the end of the ine.

KK**!A : ds

This expression first constructs all hands with a pair of kings, subtracts all hands with an A in them, and then filters the resulting range for double suited hands.

This global filtering is just a shortcut so that you can convert something like this:

AA**{ds}|KK**{ds}|QQ**{ds}|JT98{ds} into AA**|KK**|QQ**|JT98 : ds

aasvogel,

Think I have got the last of these __ /2c issues. There was some results that were cached from before I made the fix for that issue. I have deleted them and have not been able to get any __ appearing anymore!
