Blind levels

'Blind levels' (NLH tournaments, G0): Chip EV ≠ dollar EV near jumps; name your role (short/medium/big) before you act.

Blinds go up on a schedule. A hand that was a fold at 100bb becomes a shove/fold decision at 12bb. Stack depth in big blinds is the real clock.

Before each level, glance at your BB count. If you don't know your BB stack, you don't know your strategy bucket.
