Hi Luizdn and welcome to the forums.

 

You are not alone in your perception of the success rate of finesses against robots, and it has been brought up in the forums before.

 

And each time it has been brought up it has been challenged by other forum members, and the 50% rate defended, with quite a bit of work done to show that the 50% theoretical rate stands up well to scrutiny.

 

If you want your perception to be accepted, I think you will need to present a block of a significant number of hands, from a set chosen at random, which demonstrates an 80% failure rate (or for that matter anything significantly more than 50%).

Hi there

 

I find the odds that my finesses work to be right in line with what is expected.

 

You probably did something to annoy the Bridgebase owners.

If you ask them nicely, I am sure that they will make more of your finesses work.
