CombCalc - Combinations Analysis Against Opponent Ranges

We present here to you a new computer program CombCalc. You can download user guide (3d-book, 3d-view). This program can help you to calculate your starting hands chances against opponent starting hands range. In second part of this article we will describe how you may use this program to improve your skill. The program was developed by association with “Combinatorics” post of  derosnec. CombCalc comes in two different flavors. Trial and Pro version (with free lifetime upgrades!).The following screen shot is the main program window. It can look differently on your computer. There is word “Trial” in the Main Window Title and there is “Registration” tab. It means you have trial version. Trial version`s only limitation is inability to create own ranges. Let us use ranges from PokerStove, Equilab etc. You will be able to create your own ranges as soon as you register.
Pro version registration:

Now let us follow the derosnec article and assume we have pair of Queens as pocket cards. This hand can be selected by clicking button next to “Hero” header in Hands pane. Cards pane pops up (pic.1-6) and we can select  QsQc (queen of spades and queen of clubs).

Continue reading the article. Ad6d7h (Ace of diamons, 6 of diamonds and 7 of hearts) are flop cards. Flop, river and turn cards are seleced in the Card pane. Please refer to pic.1-7.

Now pick opponent`s card range. For example, VPIP is 20%. VPIP is Voluntarily Put Money In The Pot Percentage. Input 20% in the text field next to Op1 and press button.


Pic.1-8. The opponent`s range is 20% of all hands

Open a new window “Hand Range Op1”. Down we can see a slider for PFR (Preflop Raise Percentage) and VPIP definition. In this matrix view there is number of combinations with Hero and board cards taken in account. There are 3 suited AKs and 9 off suited AKo combinations resulting in 12 AK combinations. On the top right we can see our equity versus opponent equity. Without considering blocking cards range consisting of 270 combinations from all 1326 pocket cards. With considering the blocking cards 198 combs left in the opponent range. 114 of those are winning combinations and 83 are losing ones, 1 comb is resulting in draw. Opponent range contains 40 pairs, 68 aces, 63 suited combs and the combs by suits. In this case only hearts can be a worry for us. There are only 20 such combs. Let’s move to the next example from the article. Clear open cards and choose a new cards. Assume that АсАs and QsJdJh came on flop. Let opponent have the same range as article range: 22+, А8+, К9+, Q9+, J9+, T8+, 98, 76. Input the range with Copy and Paste. Then press button Op1 . Please refer to pic.1-9

4 combs AQo and 2 combs AQs (AQ – 6 combs). KQ – 12 combs etc. Remove combs that opponent supposedly folds on flop. Remove 22-88,А8,А9. Please refer to pic.1-10

Pic.1-10. AA versus range 22+, А8+, К9+, Q9+, J9+, T8+, 98, 76 after Hero bet on the flop


156 combs are winning, 38 combs are losing. Same result as in the article! Now let`s consider second opponent. Let`s suppose he has 10% range and press Op2 button and drag Hand Range Ор2 tab to the right. Please refer to pic.1-11
