What are preflop opening ranges?
A preflop opening range is the set of starting hands you raise with when everyone folds to you. It's the single most important — and most learnable — decision in poker, because it's finite: there are only 169 starting hand classes, and for each seat the answer is a fixed “raise or fold.” Memorize the charts and you'll never be lost before the flop again.
Why position changes everything
The later you act, the more hands you can profitably open — because fewer players are left to wake up with a big hand. That's why the button opens far wider than under the gun:
- Under the Gun:open the top ~14% of hands — First to act with the whole table behind you — play tight.
- Hijack:open the top ~19% of hands — A couple of seats from the button — open a bit wider.
- Cutoff:open the top ~27% of hands — Late position — only the button acts after you, so steal more.
- the Button:open the top ~45% of hands — Best seat in poker — you act last every street, so open wide.
- Small Blind:open the top ~40% of hands — Only the big blind behind you — raise or fold, never limp.
How much should you raise?
When you open, raise to a consistent ~2.5–3 big blindsfrom every seat — unlike postflop, preflop open sizing barely changes by position, so there's almost nothing to memorize. Note that the pot-fraction sizing you may have heard of (half pot, two-thirds pot) is a postflopskill, not a preflop one. And when it folds to you, it's raise or fold— never just call (“limp”), which is a common beginner leak.
