Enter your hole cards, add community cards, and set the number of opponents to see how your equity changes street by street. It also compares pot odds to your hand odds so you can tell when a call is profitable. Use it to study spots you play often or to build intuition away from the table.

Understanding Expected Value (EV)
+EV (Positive Expected Value): Over many hands, this play makes money on average. Even if you lose this hand, it's the right decision mathematically.
-EV (Negative Expected Value): This play loses money long-term. Even if you win this hand, repeating this decision will cost you money over time.
💡 Professional poker is about making +EV decisions consistently, not winning every hand.
The Formula
Examples
Pocket Aces (AA) pre-flop vs 1 opponent
About an 85% win rate.
Flush draw on flop (9 outs)
About 35% to hit by river, about 18% on the turn.
Pot odds 3:1, hand odds 4:1 to hit
FOLD. Pot odds do not justify the call.
Pot odds 5:1, hand odds 4:1 to hit
CALL. The call is profitable long-term.
Tips & Strategies
Pot odds = (Bet you must call) / (Pot after you call). E.g., call $50 into $200 pot = $50/$250 = 1:5 = 20%
If pot odds > hand odds. calling is mathematically profitable
Flush draws have ~35% equity with 2 cards to come. ~18% with 1 card
Open-ended straight draw = 8 outs = ~32% with 2 cards. ~17% with 1 card
Position matters. being last to act is worth 10-15% equity
