According to holdemresources.net Nash calculator, with the blinds being 150/300 in a 10max SNG with 4 players with identical stacksizes left (3750c each), BU's Nash push range is 33.2% and the SB can call BU push with 2.6% of his range and the BB with 5.4%.
However, when I enter this same situation in SNG wizard and assign Nash calling ranges to SB and BB, SNG Wizard tells me that BU is supposed to push ATC. This I don't understand. Am I overlooking something? I thought that against someone who calls according to Nash calling ranges there is no better way to play than pushing according to Nash push ranges. Yet SNG Wizard tells quite another story.
Edge = 0, of course.
