A timed pot-odds drill. You're shown a pot and a bet — pick the equity you need to call, as fast as you can. Thirty seconds on the clock; every correct answer adds time pressure to your recall until the math becomes automatic.
Each round shows a pot size and an opponent's bet. Choose the break-even equity you'd need to call. You have 30 seconds — answer as many as you can.
Pot odds tell you the minimum equity a hand needs to make calling a bet profitable. The formula is simple: divide the amount you have to call by the total pot after you call.
Say the pot is 100 and your opponent bets 50. You call 50 to play for a final pot of 200 (the 100 + their 50 + your 50). Your required equity is 50 / 200 = 25%. If your hand wins more than 25% of the time, calling is profitable. That's exactly what this trainer drills — fast.
Most real decisions cluster around a handful of standard bet sizes. Learn these anchors and you'll rarely need to do the full calculation:
| Opponent bets | Equity needed |
|---|---|
| 1/3 pot | 20% |
| 1/2 pot | 25% |
| 2/3 pot | 28.5% |
| 3/4 pot | 30% |
| Full pot | 33% |
| 2x pot (overbet) | 40% |
Once you know the equity you need, compare it to your hand's actual equity. On a draw, the Rule of 2 and 4 gives a fast estimate: multiply your outs by 4 on the flop (for both cards to come) or by 2 on the turn. A flush draw has 9 outs ≈ 36% on the flop — an easy call against a half-pot bet.
Pot odds only count the chips already in the middle. When you have a draw that can win a big pot later, factor in implied odds too. For the full framework, see the study guide, and drill your preflop ranges in the preflop trainer.
