Hi I've just started public testing of my new online equity calculator which is available at http://www.evplusplus.com/poker_tool...ty_calculator/ It supports Holdem, Omaha, Stud and Draw games.

Here's a couple of shots of the interface:





and some sample output (select TwoPlusTwo as output format):

Player 2	3569T	61.92	0.00	0.619

I'm open to suggestions on how it can be improved, different output formats etc. so let me know what you think!

Cheers,

nice work. is this based off the pokersource/pokenum code thats out there?

Thanks greg.

Yup it's the pokenum code, same engine as the twodimes calculator just with a little nicer (imo) interface.

Looks very nice! Good work.

Juk

Very cool tools! Thanks!

I've been thinking about what I would like in an equity calculator and it would be ideal if I could assign opponents probabilities for certain ranges. IE. I hold AKQJds the villain 3bets me and I decide there is a 70% chance he has AAxx double suited and a 30% chance he has QKTJds what is my preflop equity against those ranges and percentages?

I'm not even sure if this is possible with the current poker evaluation packages but thought it would be nice.

Thanks guys!

rwdvc,

That would be a neat tool and I believe something similar to that exists right now but for Holdem only. Check out the Stoxpoker EV (or something like that) program http://forumserver.twoplustwo.com/45...leased-155966/

Yeah but I only play omaha unfortunately!

Bump!

I have added support for pokerstove like ranges now for Holdem. Omaha range support in the works.

Player 1	A2s+,JJ-88	47.47	3.63	49.283
Player 2	K9s-KTs	48.90	3.63	50.717

Just fixed a small bug in the range selection methods.

I've also added support for % based ranges e.g. you can enter 20% to get the top 20% of hands.

Bump!

I'm happy to announce that ranges are now supported for Omaha, Omaha 8/b & Holdem!

Player 2	AA**	6	5.14	0.00	4.67	2.56	5.11	7.84

I will likely add more functionality later. But I'm on vacation now for a couple of days

Time for another bump as I've made a number of small bug fixes so everything should be running a bit smoother now. I have also added a new range selection tool for holdem:




I will also be moving the site to a faster/more powerful server in the next couple of days so simulations should be even quicker.

Just made the next big release of the equity calculator and I have added a couple major features including:

• Powerful Range Syntax for Holdem, Omaha and Omaha 8/b
• A Hand Range Inspection Tool
• Street-by-Street Equity Calculations
• Hand Range Combo Counting
• More Output Formats
• Filtering for suits and pairs
• Should be more stable than the previous version.

The new range syntax allows you to write range expressions like:

• 5% ! (AA|KK) == the top 5% of hands not including AA or KK
• [JT][98] == double suited J high rundown
• [A*]h[A*]s == double suited aces
• (10 -15% {ss}) | AhA** == single suited hands in the top 10-15% OR any pair of aces including the Ah
• and more.

The ranges can be as simple (eg AhKc) or as complicated as you like. Please note that there is some differences in the syntax compared to PokerStove mostly in regards to the way you specify suited/offsuit cards. In Stove writing AKs will give you all AK suited hands. In ev++'s calculator AKs means any A with the K of spades. To get any AK suited you would write [AK], to get AK suited in hearts you would write [AK]h and so on.

Documentation for all the range syntax is available at http://www.evplusplus.com/poker_tool..****ulator/docs/ and some more examples are available at http://www.evplusplus.com/poker_tool...docs/examples/.

There is also now a hand range exploring tool at www.evplusplus.com/poker_tools/hand_ranges/ that allows you to enumerate all hands in a range to ensure it contains the hands you were thinking of.

Hope people enjoy the new version...I've had a lot of fun developing it and would appreciate feeback from anyone (Google Analytics tells me there's a bunch of you so I know you're out there!)

I only see HE, O, & O8 in the drop down game selection box.

Where is stud and draw?

Sorry I took those out temporarily because they broke with the latest update. They will be back online in a couple of hours.

Seven Stud, Seven Stud 8 or better, Razz and Deuce to Seven Lowball equity calculations are back online.

anyway you can port this as a standalone app? commandline if need be

I will actually be starting work on that shortly. No estimate of when that will be ready though. I will need some testers for that. If you are interested in being a tester PM me or post here.

It seems to work fine for Omaha and Omaha Hi/Lo for up to 6 total players. Beyond 6 players, I either get no results or I get an error like:

The error above was from simulating AsAdKsKd against 8 other random hands (using just **** for each random hand). I get the same sort of error using 100% instead of **** to indicate random hands. Is there a fixed limit on the number of random hands? Why is the simulator picking out the exact same cards for different hands?

Thansk for pointing that out to me...I hadn't run more than 4 or 5 random hands I think so I will look into/fix that.

The code picks out a random hand from each players range, then checks to make sure there are no duplicate cards, if there is, it throws them out and picks another hand. I have a catch in place so that if that happens too many times it throws an error. This is to prevent a situation where every hand in 2 players ranges contained say, the 2 of clubs.

I think it should be an easy fix but won't be up until tomorrow probably.

Thanks again.

Ok that problem is fixed now. I also fixed a bug that was causing filters like !qu (e.g. AA**{!qu}) to fail.

Thanks again aasvogel.

BTW if anyone has any questions about how to construct certain ranges for Omaha or Holdem, feel free to post them here and I will be happy to explain them and add them to my examples page.

I've gotten this error several times when trying to access the calculator, and even when just trying to access the home page at www.evplusplus.com:

Bandwidth problems?

ARGH!

I've been trying to track down what is causing this for a couple of days. It's not a bandwidth issue but something is causing my server to get pegged at 100% cpu usage which doesn't allow it to serve the pages. My apologies I hope to crush that problem today.

Very nice work. It will be particularly useful for Mac users that can't use Pokerstove.

Not sure what's going on here:

Compare that to the Beta simulator on PPT:

I would definitely prefer to play 2d3c4h7h at the table being simulated by ev++.
