Equity
 

I here so much about equity in books and people on the internet, especially for SNG's. Can someone give a quick rundown on what this is, and whether equity calculations can be made in game? Or is it something we use to analyse our game after playing, and reviewing our hand histories?

Thanks

Equity means the expected value of something. It can refer to your expected share of the pot if there is no more betting, or your expected share of the prize money in a tournament.

SNGs may be mentioned because push or fold decisions are very common in SNGs, so you might see someone say that they have 45% equity against a tight calling range. Equity may also be mentioned because the single table tournament prize structures reward making the money much more than in other tournaments relative to winning, which means the chips do not all have the same value. An imperfect but useful tool for estimating your tournament equity from the stack sizes is the Independent Chip Model (ICM).

In general, you can't perform a complicated equity calculation of either type at the table. You study situations ahead of time, and make an educated guess while you play.

Thanks. Are ICM calculators any good for whilst playing? Lets say im playing in a SnG, and i have A-10 suited, one player pushes all in everyone else folds. Can i put stack sizes into the calculate to check my equity, and then use that to decide whether to call or not?

If you can do this, what is a "good equity" figure, which would make this call worthwhile?

Thanks.

It's really not practical to be loading info into an ICM prog. while playing a game.

#1 You won't have time.
#2 You'll start to rely on the thing so much that you'll hinder your progress as a player.

Analyze your hands and plays AFTER a session, calculate whatever you want/need to then. After studying the figures, you'll start to intuitively know what lines to take in certain situations.

Agreed - do your poker homework between/after sessions. Apply what you learn during them. Your best guess is generally all you have time for. If you can, make a note of the hand on a piece of paper as one to review later (this is what I did - I'd tag a handful of hands while 4 tabling (generally the hole cards TT, ATo, AKs, etc) and find the hand in PokerTracker later.

Re: Equity
 

To add to Sell's post above, I always keep a notepad handy when I'm playing a session. If I run into any interesting situations I don't really know how to handle, or think I could have handled better, I write down the hand #.

At the end of every poker day I print out a summary, including the PT summary screen, the PT positional stats screen, the session summary screen and some key hands. The key hands I'll print out include the ones I jotted down on the pad, and my biggest losing hands for each table that PT shows me. These all go in a big binder. It's important to keep good records when you're trying to move up stakes, or improve at all.

I'll go through each hand, and on the printed HH I will (at least attempt to) make calculations and evaluate my play.

When I first started doing this, it just seemed like a huge pain in the ass- I do enough math in Econometrics class. But it really forces you to think about your game on a deeper level, and although you might not realize it in the moment, your understanding of poker will increase tenfold, and quite rapidly as well.

Re: Equity
 

While I agree with the stuff everybody wrote, I would also like to state that just understanding the concept of equity and its application to SnGs should improve your game tremendously there, even pre-ICM calculations. Before, I simply played pot-odds and induced much higher variance to my winnings. Post-equity concept (I still don't do ICM calculations) my variance has become much tinier and my winnings more consistent. I have become much more intuitive regarding choosing good spots to play for all my chips, particularly around the bubble.

The next stage of my development, of course, is to do the same things the guys above me suggest. However, I just figured I would mention that prior to doing extensive calculations on your hand-histories, you should really try to understand equity theoretically, particularly as it applies to SnGs. You may find that after you accomplish this, your game will on need some fine-tuning on the experimental level.

Re: Equity
 

Ok thanks guys!

Also does anyone know of some handy websites that has a complete list of all the common hand match ups pre flop, such as over pair vs under pair, over cards vs under pair etc, and all the drawing odds of flush, straight, straight flush draws etc that i can print and keep handy while playing. This way it will be easy for me to compare the pot odds poker office gives me while playing, to the odds of making the draw to see if a call is sufficient. Thanks.

No, not really. Equity refers to the value of your ownership in property. For example, if the market value of your house is $100,000, but you owe the bank $30,000, you have a $70,000 equity.

Precisely, but relative to the meaning of equity, the key word is share. Also, I guess my first paragraph was nitpicky.

Pzhon, I really appreciate the time you invest in answering questions. I've learned a lot from you.
