Theory of freeroll (equity)
Lets assume you are playing omaha and get all in with a complete freeroll such as this situation. http://twodimes.net/poker/?g=o&b=8s+...%0Ajc+qs+2h+3d
Usually its (%chance win)(pot size)-(%chance lose)(pot size) to calculate equity. Is it correct therefore to lets say in an all-in 200 dollar pot to calculate your EV as (.615)(200)-(0)(200)=$130 or am I missing something? |

Re: Theory of freeroll (equity)
Well, in a freeroll you have a base line that is the same as a split pot.
So you already own half the pot - its the rest you are freerolling for - your original algorithm dont take into account the chance of a split pot. Add +(%chance split)(pot size) |

Re: Theory of freeroll (equity)
i think the expression should be
(.615)(200)-(0)(0) b/c you can never lose money in this scenario. (it's a bit nit picky, but you lose no money, 0% of the time) also, the equation should give ~123 [ QUOTE ] Usually its (%chance win)(pot size)-(%chance lose)(pot size) to calculate equity. [/ QUOTE ] a normal ev calc applies here, it's just looks a little different than a standard poker ev calc b/c you can never lose money in a free roll. you could also say (win freq)*potsize + (chop freq)*0.5*potsize = (.229)*200 + (.771)*0.5*200 = (.229 + .771*.5)*200 (.615)*200 so you get the same result |
