raising with draws - how much FE needed?

[jay_shark]

I will make some further simplifications to the formula .

(SPR-1)/(SPR+5) = (SPR +5 -6)/(SPR +5) = 1 - 6/(SPR+5)

That is , the push is neutral EV if you expect to be called 6/(SPR+5) .This is actually quite nice as it's very easy to do this calculation on the spot during a difficult situation .

So in the original example , as long as you get called
6 /7.416666 , then the push makes no difference .If you expect to be called less than that number then the push is positive EV .
