At 1000bb the CO still steals relentlessly — with suited, connected cards. Offsuit is down to the elite.
Only hands that can make the nuts — or fold without regret — belong in the range. Offsuit big cards win small pots and lose enormous ones.
The cutoff attacks the button and the blinds. This is the first position where pure steal equity carries a meaningful share of the range.
Assumes a live-standard open to ~4bb, raise-or-fold. In straddled games, halve your effective big blinds and read the chart at that depth.
