A tight-aggressive 6-max opening chart looks like this:
Always open (any ): AA, KK, QQ, JJ, AKs, AKo, AQs, TT, KQs, AJs, AQo, KJs, 99, ATs, QJs, 88, KTs, QTs — roughly the top 13%.
MP adds: 77, AJo, JTs, A9s, KJo, 66, some suited Ax (A5s, A4s), T9s.
CO adds: 55, 44, more suited Ax (A8s–A2s), KQo, QJo, K9s, Q9s, J9s, 98s, ATo.
adds: 22, 33, K2s–K8s, Q8s, J8s, T8s, suited connectors down to 54s, KTo, QTo, JTo, offsuit broadways.
The pattern: as improves, you add suited hands first (they play better on all streets), then small-medium offsuit hands, then dominated offsuit broadways.
Never limp (call the first-in). Always raise to 2.5–3x.
Key points
✓Top 13% opens from every position including UTG
✓Add suited hands first as you move toward the button
✓Suited is always wider than offsuit — they make flushes + straights
✓Offsuit broadways (KTo, QTo, JTo) only open from BTN+
