Street-by-Street Poker EV Graphs with SECT

SECT: Showdown Equity CalculaTor

SECT: Showdown Equity CalculaTor

Let’s say you have AA on the button with 100bb stacks. You misclick and accidentally raise to 99bb. Villain, a crazy billionaire railroad tycoon, has 27 offsuit and decides to call. The flop comes 222 and the pot is 198bb. Villain shoves his last 1bb and you obviously call.

HEM and PTR will calculate your EV only when you go all-in. In other words, you have 0.1% equity on the flop (when you went all-in) and that translates to about 0.2bb in EV. That is obviously painting a very distorted picture…

But that’s where SECT comes in. It calculates EV street-by-street. So in other words, 99bb went in when you had 88% equity and 1bb went in when you had 0.1% equity. SECT will report your EV as 174bb (a much more accurate representation of what’s happening).

SECT only works for cash game hands and it reads off an HEM database (sorry PTR folks, you’re out of luck).

To install:

  1. Download the latest Java update.
  2. Download SECT
  3. Uncompress the .rar file (you might need Winrar)
  4. Edit the XML file in notepad (see steps 5 7)
  5. Replace “HoldEmManger” with the name of your database
  6. Replace “postgres” by your postresql login
  7. Replace “postrepass” by your postresql password
  8. Run SECT_v3.2.7.jar

Forgot the name of your database or your login information? Here’s how you can find it in HEM.

In the example above, my database name is 2008.  Youll see your Login name and Password once you click on Database Management.

    Interesting this is what Ive been looking for I had planned on writing this software street by street luck factor. I didnt because in the end, what does it prove? That youre lucky or unlucky. The thing is: who cares? Did you play the street correctly is a more subjective question, but thats what you want to be sure of. However, if this does PT3, it is definitely a worthy tool, similar to Holdem Luck.

    Thanks, Gugel!

    Does this work for omaha? Cant seem to get it running but maybe its an NLHE tool only?
