Table 6. Multiplication factor to calculate implied odds based on our<br />

equity.<br />

Our Equity Multiply his bet by:<br />

35% 2x<br />

25% 3x<br />

20% 4x<br />

15% 6x<br />

10% 9x<br />

Table 6 shows how much money we need to make when calling<br />

a bet. This is based on our equity. Let's use a quick example to<br />

show this at work. Let's say you're in a hand and you have 20%<br />

equity on the turn. The pot is $20, and your opponent bets $10.<br />

Since you have 20% equity, you look at the bet you must call<br />

and multiply it times 4 (See Table 6). His bet is $10, so we need<br />

$40. Now, there is already $30 in the pot (The $20 plus his<br />

$10.), so we subtract that from what we need.<br />

$40 - $30 = $10<br />

So, we need $10 more to breakeven on this call. Notice if we<br />

call, the pot would be $40. So, we need to be able to get a 1/4<br />

pot bet on the river.<br />

Let's look at our 67s versus AK hand again. Remember, we<br />

know his hand, he doesn't know ours. He has $20 left after his<br />

$5 bet, and we know his hand is very strong. He bets $5 into a<br />

$10 pot. We know we'll catch our straight about 16% of the<br />

time, but looking only at immediate pot odds, we need to be<br />

good 25% to call. So, we consider how much we need to get on<br />

the river to at least break even. Looking at our chart, we can<br />

estimate we need about 6x more (a bit less) than his turn bet.<br />

His turn bet was $5, so we need $30 (6 x 5) to make the call.
