Hi there,

Hope some one can help with this theoretical question. If I'm on button with no preceding action, and the two players behind (neither are short) will call a my 10bb short stacked shove with 25% of hands, does that mean that the combined chance of a call (from either player) would be 50%?

Thanks in advance.

Not exactly.

If you assume independence, it's 1 - .75^2 which is about 44%

Many thanks guys

Ultimately, I think we should care about the times SB calls and BB calls. If we assume SB is calling with 25% of hands, and BB will call with 25% if SB folds, there will be some smaller range, say top 10%, with which BB will call even if SB calls. In this case, our equity when called is much worse than it was if we assume one caller with a top 25% range.

Which is why I think that just adding up the percent of their calling ranges is an OK approximation.
