When Should You Enter Push/Fold Mode In A Poker Tournament?

Players Typically Transition Into Strict Push/Fold Strategy Below 12 To 15 Big Blinds. At This Stack Depth, Non-All-In Open Raises Risk 20% Or More Of Your Stack Without Leaving Room To Maneuver Postflop.

How Do Big Blind Antes Affect Push/Fold Ranges?

A Standard 100% Big Blind Ante (12.5% Per Player At An 8-Handed Table) Increases The Uncontested Dead Money From 1.5 BB To 2.5 BB, Widening Optimal Open-Shove Ranges By 25% To 40% In Late Position.

Why Is Calling An All-In Tighter Than Shoving Yourself?

When You Open-Shove, You Benefit From Both Fold Equity And Showdown Equity. When Calling An Existing All-In, Fold Equity Is Zero And You Rely Entirely On Raw Card Equity Against A Concentrated Range.
