How to use ICMIZER – quick reference

When you want to analyze a situation from a tournament in ICMIZER follow the next steps:

  1. Select (or create if required) a payout structure, blind structure (or create if required) and number of players
  2. Fill in the stacks of all players, according to their positions.
  3. Choose your position and betsize (if it is a hand where you are restolen from later position) and set up opponent bets (pushes, steals, etc.)
  4. Most important step – select appropriate ranges for your opponents or opponent. Use range edit popup control, either type in the range or use sliders to quickly assign a range to opponent.
  5. Once you have filled all the information about the hand ( all previous steps) you can press [Calculate]. You will see the results for your hand that show EV of push (when you go all-in) and EV of fold (when you decide not to take part in hand). The green color of EvDiff % value is usually a good thing, the red color means you are better of folding with your hand. In Range result textbox you can see the range of all hands that have desired EvDiff% ( EV push – EV fold > min Ev diff), this is the whole range of hands you can profitably push in such situation.

You can also click [Charts] button to view charts for current situation. If you want to save results and share them with others press [Save current result] button.

Most of the input can be done by means of Parse button function, just copy the poker hand into clipboard and click Paste. Most information will be loaded automatically, you just need to assign ranges in most cases.

ICMIZER supports ICM calcuations for following poker situations

  • Push spot – when you are first to open and consider whether or not to go all-in (including pontential overcalls or 3 way spots)
  • Call spot – when you face an all-in in front of you and consider whether or not you can call profitably
  • Overcall spot – when you face two all-ins in front of you and consider whether or not you can overcall profitably
  • Resteal spot – when you face a steal in front of you and consider whether or not you can resteal profitably
  • Restolen spot – when you raise (steal) and face a resteal push from late position

Creating new payout structures

ICMIZER provides an easy way to create new user defined payout structures:

create new user defined poker tournament payout structure

Here you first select the name for new payout. Next you can choose creation mode: percent mode or dollar mode. In percent mode you simply input payouts as percents of prize pool. In dollar mode you first specify number of players and buy in (part that goes to prize pool). Next you input payouts in dollar, this is often desirable when you are creating a payout for an existing tournament. Once you have finished inputting significant payouts (for example anything more than number of players is not significant) you can press [Done] button and then click [Ok]. The new payout will be created and will become selected. If you input wrong payout just press [Delete last] button and enter the right one.

Basic ICM Calculator

Here http://www.icmpoker.com/icmizer/#icmcalculator you can find the most convenient and good looking "basic ICM calculator" available online.

best online poker icm calculator ICMIZER

It can be used for some manual ICM based calculations, or maybe when you are considering an ICM chop on final table in a MTT situation. A click on the button in the main ICMIZER window transfers currently inputted stack values and payout structure into ICM Calculator and calculates players ICM Expected Values. This ICM Calculator also has the same form to create new payout structures as shown above. It provides a way to view ICM expected values in three display modes – dollars, decimal fractions and percents.

Hand Parsing

A click on the analyze hand history from poker client online ICM based button allows to quickly load a hand from clipboard into ICMIZER (payouts, player stacks, blinds, and mode if it can be inferred from hand). To use this feature, please let www.icmpoker.com website to access your clipboard, when related dialog window pops up.

Currently supported hand history formats are: PokerStars, FullTilt, PartyPoker, Cereus

Sharing ICMIZER results with others

One of the most impressive and innovative features of ICMIZER is ability to create a permanent link to a situation that you are currently analyzing. Just fill in all the data (mode, players count, stacks, ranges, etc.) and click create a link to share poker ICM situation on forum or aim

The following window will pop up:

create a link to share poker ICM situation on forum or aim, ICMIZER link view

Copy this link (press [copy] button or select the url and press CTRL+C) from this window and you can share it with others on a forum or with your friends in AIM. Upon clicking and following provided link others will see ICMIZER in the same stated as you have saved it and will get a quick access to calculations in this case without any additional input on their part. Just clicking calculate buttons or build charts button is enough. Also create link function can be used to save a nonstandard payout structure that you need for your daily calculations. Then you can use a saved link to avoid creation of this payout structure again.

Default options in ICMIZER

Charts in ICMIZER

An interesting and a powerful feature of ICMIZER is ability to build charts, instead of making usual calculations. Press the charts for poker tournaments ICM calculations online button in order to get access to two types of charts.

Range chart

The first type of chart is a range chart. On this graph horizontal X axis is representing a supposed opponent range, and on vertical Y axis you can find a matching push range for yourself. In this mode ICMIZER completely ignores both your pocket hand (the cards you are dealt in this hand) and any input for opponent ranges (except for the opponent raise range in Resteal mode). Let’s see at a simple example, we are heads up and payout structure is a winner take all structure (first place gets 100% prize pool). We have got 10 big blinds. Go to http://www.icmpoker.com/icmizer/#PFkk click and you will observe the following chart:

push range chart for poker tournaments ICM calculations online

We are hovering mouse over a point, where opponent call range is roughly 40% (X axis). In this case a chart legend is showing us that for MinDiff% equal to 0% (a situation where it is irrelevant to us whether we push or fold, a border case) we can push with 53.2% hands (Y Axis). If we want our push to be +0.2% ev we should be pushing 50.5% hands, and in case when we want 0.5% edge (probably too much for heads up situation) we need to narrow our push range to 45.4% hands.

Minimal yellow value on Y axis on range chart always is showing our unexploitable range. Unexploitable range is a range against which our opponent cannot pick a range that will make our push unprofitable, even if he/she precisely knows our range. Usually in Push mode range chart will have a part in the left side of X axis where when opponents are calling too tight hero can often shove with a 100% range or with any two cards. The key here is to be able to make correct assumptions about opponent call ranges, because often a mistake in doing that will mean that a plus EV push quickly becomes a big minus EV decision.

Next example will be about range chart in Call mode: http://www.icmpoker.com/icmizer/#dgmD

call range chart for poker tournaments ICM calculations online

In Call mode range chart usually looks like a triangle, whose vertical side is less than horizontal. So in this case if our opponent is going all-in with 64% hands (like on the image) hero can profitably call only with ~41.5% hands, which is roughly two thirds of opponent push range. It is interesting that such a ratio between opponent shove range and hero call range remains approximately the same regardless of opponent range. Such slope is not very typical for call range, usually our call range is much narrower than opponent push range, but here we are heads up and payouts are 100% for the first place finish. When we are on the bubble and when the payout structure is more evened out, the percent of hands we can call with from the raisers range tends to be lower. In extreme cases our opponent can be opening with 100% of hands and we will be limited to call on our top range like top 5% hands or even less.

The last kind of range chart is Resteal chart. http://www.icmpoker.com/icmizer/#uPFi

We are looking at a typical super turbo heads up situation: our opponent raises from 20 to 40 with a wide range (81%)

resteal range chart for poker tournaments ICM calculations online

When a range chart is built in Resteal mode opponent call range is varied in % from approximately 0% of raise range to 100% ( so in this case if opponent is raising 81% he/she is also calling with the whole 81% range, which means he/she is always calling, once he/she raises).

For each corresponding call range a hero range is calculated, that he/she can profitably push with. As we can see from chart, in this case if opponent is raising 81% and is calling in less than 25% of cases hero can be restealing very wide (67.7% hands show 0% EV or better for resteal instead of fold).

Hand EV chart

The second type of chart is a Hand EV chart against opponent range. When building such chart ICMIZER is taking a known hero hand ( pocket hand, for example aces or 87s) and varies opponent range. For each situation an EV value is calculated (EV push – EV fold for hero with known hand). In such mode some rules of thumb usually apply. Like the better your hand is the more profitable it is for you a situation when you are called or shoved at light. Or the worse your hand, the more profitable it is for us when opponent is playing tightly. There also exist some interesting intermediate situations where average opponent range is not a good case for us, but when he/she is more tight or more loose we can play our hand profitably. This is usually true for middle strength hands of her like broadway cards or medium AX type hands.

Example EV Hand chart for Push mode: http://www.icmpoker.com/icmizer/#nBcg

We are holding KQo and we are going all-in. Now let’s see the EV of such move, depending on the opponent call range

push hand EV chart for poker tournaments ICM calculations online

Here we can choose opponents call range with mouse, and after that we can see EV Diff% for pushing KQo (6.75% of total prize pool for call range equal to 39.7% hands on sample image). In push mode most hands usually have a situation when EV diff% is greater than zero, usually when our opponents are calling too tight.

EV Hand Chart in Call mode: http://www.icmpoker.com/icmizer/#YXVE

We are holding QJs and we are facing an all-in from small blind in heads up.

call hand EV chart for poker tournaments ICM calculations online

We call clearly say from this chart – if our opponents push range is very tight calling becomes a very costly mistake. But in the region of push range greater than 30% of hands QJs power becomes enough for a profitable call. Type of Call mode EV Hand chart varies when we change our hand strength.

Last type of EV Hand chart is for Resteal mode: http://www.icmpoker.com/icmizer/#kuPE

Suppose we are on the bubble of a 9 max SNG. We are holding the same stack as the chip leader, who is stealing very wide from cut off position. We are on the button. We got an average hand which can’t be easily dominated – J9s.

resteal hand EV chart for poker tournaments ICM calculations online

After looking at the chart we can say, that if our opponent is calling too rarely pushing becomes very profitable to us. But in case our opponent is not very good with ICM and might not only raise light, but call light too, we are forced to fold.
