I have being playing 4 tables doing this strategy on Empire/party poker for the last week...

I record every pre flop all in and intend to run all the hands through pokerstove to calculate the average theretical edge I have. Then I will calculate with the binomial formula the probability to have this "bad luck"

So far I have lost clearly more than won despite very often having a dominating hand. This is pretty much what I expected from my earlier Empire/party poker experience. The data set is statistically still too small, but it sure doesn't look like the cards are falling randomly at all!

pre flop all in results against one opponent:

won 57
lost 66

I will count a dominating hand as a one which has a 2 to 1 chance of winning

Dominating hands held: 67
Dominated hands held: 12

So far it doesn't look good, but I will keep on playing to see if the results get any closer to the expected values.
