Hi, I was just practicing with the ICM Trainer and was a little surprised about a pushing range (Any two), so I checked the situation with the HoldemResources Nash Calculator. HoldemResources says to push 49.9% in this spot. Unless I made a mistake I do not understand why there is such a big difference in the ranges. Can someone explain it to me?

HoldemResources Nash Results

Edit: OK, I just realized that there was set an edge of 3%. When I put it to 0% it is approximately the same range. But now I ask myself why 3% edge can affect the result so much???
