Alright… so I just tried to calculate how big of a raise you should call when you have an OESD. This is meant for situations where you are pretty sure you will be able to win a good amount if you hit.
i.e.: you think your opponent has a set or 2pairs, which most people at low stakes won’t usually fold.


the odds of hitting the straight on the turn..

8/47
.170
1 in 5.88

Chance of hitting on the river if you didn’t hit on the turn

39/47 * 8/46
.144
1 in 6.94

Odds of hitting your straight

1 - ( 39/47 * 38/46 )
1 - ( 0.8298 * 0.8261)
1 – 0.6855
0.3145


So over 100 of those situations, lets assume you’ll hit the straight 17times on the turn and 14times on the river.

So you’ll call looking for the straight 100 times on the flop, and 83 times on the turn. (17 times you’ll already have the straight on the turn)

You’ll win 31 hands.

Now let’s calculate the maximum amount to call.

x = amount you can win… pot + your opponents stack (or yours if its smaller)
y = total of calls

31x = 183y
0.169x = y

Or

y = 5.91x


Would it be correct to make a rule such as “call a raise only if the amount you can win is 7x bigger. “ ? (7 for profit and chance of your opponent folding)
