Poker Calculator Online
How many times have you rushed into a river bet, only to lose a pot when it was a close
call whether you should have been involved?
Improving at poker is all about going back and re-assessing your old hands. All good
poker sites have 'History' options where you can look back at hands, but using a poker
calculator is better still.
What is a Poker Calculator?
A poker calculator works out the odds of you winning a hand in any given situation. It
can, in some circumstances, be used while you play, but they're particularly good for
revisiting old hands so you can learn from your mistakes.
You tell the calculator what hand you're holding, in what position, and what your
opponent has. Then, you select from a bank of playing cards to decide the flop, turn and
river, and the calculator will display the changing odds of the hand on-screen.
Use a Poker Calculator For:
- Texas Hold'em
- 7-card Stud Hi/Hi-Lo
- Omaha Hi/Hi-Lo
How Does it Work?
First, select your game, whether it's Hold'em, Omaha or Stud. Input your own hole cards
and the cards of your opponent or opponents, and then hit the 'Calculate Odds' button.
You can reset the board any time.
Now, it's possible to work out whether it was right to chase that flush draw, whether
calling with trips on the flop when your opponent needed four outs to a flush was smart,
or whether you're really learning from the game at all.
Effectively, the calculator takes a few things into consideration:
You know how many
cards are left in the deck, and how many have been dealt out/burned. You also know your
outs (cards in the deck that can improve your hand) and what those particular outs are.
Poker Calculator In Action
Game: No Limit Texas Hold'em
You: Jd 10d
Opponent: Ad Jh
Board: 10c 8d 9h Jc
In a big hand you played online, you're sitting with J-10 suited and find an aggressive
opponent behind you. From the history you see he held Ad Jh.
After a raise and call, the flop comes 10c 8d 9h. With top-pair you hit
the 'Calculate Odds' button and see that you have a 90.81 percent chance of winning the
hand after the flop.
You bet, and with an open-ended straight draw the opponent calls. The turn comes a Jack,
giving you two-pair but also potentially completing your opponent's straight. Hitting
the 'Calculate Odds' sees your win chances reduce to 74.94 percent.
Now you're a little more cautious. You lead out again, and your opponent calls. The river
comes a meaningless 2d and you win the hand with two-pair. However, even with the clubs
on the board and the straight draw, you're still almost a 75 percent shot to win the
Why is Calculating Odds Important?

kit without spending a cent.
