Preflop fundamentals: position, ranges, and why not to limp

Every hand, the player who acts last after the flop has a massive edge: they see what everyone else does before deciding. That seat is the button (BTN), and it's why your range should change dramatically by position.

Think of the table in three buckets:

• Early position (UTH, UTG+1) — many players still to act behind you. Play tight: roughly the top 12-15% of hands.
• Middle / Cutoff (CO) — fewer left to act. Open wider, around 20-28%.
• Button — only the two blinds behind you. This is the printing press: open 40-50% of hands.

The single biggest beginner leak is playing the same hands from every seat. K-9 offsuit is a fold under the gun and a clear open on the button. Same cards, opposite decision — because position changes everything.

Limping (just calling the big blind instead of raising) feels safe. It is almost always a mistake, and it's the leak the trainer will flag fastest. Here's why:

• You give up the pot for free. When you raise, players often fold and you win the blinds uncontested. Limp, and nobody folds — you've guaranteed a multiway pot with a weak hand and no initiative.
• You cap your hand. Strong players know limpers rarely have aces or kings, so they punish you by raising over your limp (isolating). Now you're playing a bloated pot out of position with a marginal hand.
• You forfeit the betting lead. The preflop raiser gets to continuation-bet the flop and win without a showdown. Limpers don't earn that.

Rule: if a hand is good enough to play, it's good enough to *raise*. If it's not good enough to raise, fold it. There is no third option as a beginner. (Limping behind other limpers with a speculative hand is a rare exception — ignore it until you're advanced.)

Modern tournament sizing is small and consistent. You do not need to bet big to win — a small raise risks less and folds out the same hands.

• Standard open: 2.2-2.5bb when first into the pot. At 100bb deep, 2.2bb is plenty.
• Add 1bb per limper. If one player limped, raise to ~3.5bb to charge them and discourage callers.
• Tables with antes (later levels): you can size up slightly to ~2.5bb since there's more dead money worth taking down.

Keep the size identical whether you have A-A or A-J suited. Varying your raise size by hand strength is a giant tell that good players and the trainer's bots will exploit. One sizing, every hand, every time.

Ranges look complex, but you can carry a usable version in your head. Hands are listed as pairs, suited (s), and offsuit (o).

• Early position (~top 12%): 77+, A-J s+, A-Q o+, K-Q s. Tight and strong.
• Cutoff (~25%): 22+, A-2 s+, A-9 o+, K-9 s+, Q-9 s+, J-9 s, suited connectors down to 54s.
• Button (~45%): any pair, any suited ace, A-7 o+, K-7 s+, K-T o+, most suited connectors and one-gappers, Q-8 s+, J-8 s+.

The pattern to *feel*, not just memorize: as you move closer to the button, suited hands and connectors get added first (they flop well and play cleanly), and weak offsuit hands are added last. Offsuit junk like J-4o is never an open from anywhere.

Position and the chart assume a roughly 40bb+ stack in a normal-speed event. Two adjustments matter even for beginners:

• Getting short (under ~20bb): stop min-raising and folding. You shift toward a push-or-fold mindset — shoving all-in with your playable hands so you can't be re-raised off them. (That's its own topic, but know the gear change exists.)
• Loose, passive table: when villains call too much and rarely 3-bet, tighten your offsuit speculative opens (they realize less equity multiway) but value-bet your strong hands relentlessly. When the table is tight and folds a lot, widen your steals, especially from the cutoff and button.

Don't open-limp to 'see a cheap flop' against loose players. The fix for a loose table is *better hand selection and bigger value bets*, never limping.

Before you act, run this checklist every single hand. It eliminates the vast majority of opening leaks on its own.

1. Where am I? Identify your position bucket: early, middle/CO, or button. This sets your width.
2. Is anyone in yet? First to act = raise or fold. Limpers ahead = raise bigger (or fold trash). Never just call to 'see a flop'.
3. Raise or fold — pick one. If the hand clears your chart for this seat, make it 2.2-2.5bb (plus 1bb per limper). If it doesn't, fold without a second thought.

Master this routine and you'll already beat most of the field, who limp, open the wrong sizes, and play the same range from every chair. Tight-but-aggressive from the right positions is the entire beginner edge.
