RFI ranges by position: the practical guide

RFI means Raise First In: raise when no one has entered the pot before you. It seems simple, but it is one of the fundamentals that most separates an organized player from a lost player.

If you let go too much of UTG, you throw hard pots against strong ranges. If you let go less on the button, you leave money and chips on the table. The secret is to understand that each position has a different responsibility.

Why position changes everything

The sooner you talk, the more players can still act later. That's why the UTG range needs to be tighter. The sooner you talk, the fewer players are left and the more you can attack blinds and earlier.

A practical rule:

UTG: scratches harder and more sharply.
Hijack: starts opening more suited connectors and broadways.
Cutoff: expands a lot, especially against passive blinds.
Button: most profitable position to steal blinds.
Small blind: it depends a lot on the big blind.

UTG: discipline before creativity

At UTG, avoid opening beautiful but dominated hands. Hands like KTo, QJo and weak offsuit aces can look playable, but they often suffer against calls and 3-bets.

The UTG plan is to enter with hands that:

withstand pressure;
dominate part of the opponent's range;
they play well when called;
they don't create too many reverse implied odds.

Hijack and cutoff: where the range breathes

In hijack and cutoff, you can open more hands because there are fewer players to pass. Still, it is not license to open anything.

Dear candidates:

small and medium pairs;
suited broadways;
ases suited;
suited connectors;
some broadways off-set.

The cutoff is one of the most important positions to increase aggression. If buttons and blinds defend little, you print chips by opening more.

Button: theft with plan

The button is the best position at the table. You play post-flop last and press the blinds. But a profitable button is not a random button.

Before opening, look:

big blind defends a lot or little?
small blind 3-beta too much?
are stacks good for post-flop or push/fold?
is there a bounty involved?
do you know what to do against 3-bet?

Opening a lot on the button is good. Opening a lot without a plan is a leak.

Small blind: watch out for ego

In the small blind, you talk before the post-flop. Even against just the big blind, playing out of position makes it difficult. Against weak blinds, opening up more can be great. Against aggressive big blind, you need to defend better and choose hands that can withstand pressure.

In short stacks, small blind becomes very push/fold. In medium stacks, raise/call, raise/fold and limp can enter the strategy.

Raise size

In online tournaments, common sizes:

2.0bb to 2.2bb in medium and deep stacks;
2.0bb in phases with before;
all-in straight into short stacks;
larger adjustments against recreational players who call too much.

Don't choose size by habit. Choose by stack, position and objective.

Common RFI errors

Open too loosely from the first positions.
Open the button too tight.
Always use the same range without looking at the stack.
Ignore bounty/ICM.
Open hands that you don't know how to defend against 3-bet.
Copy table without understanding why.

How to study your RFIs

After playing, filter hands in which you were the first to enter the pot. Compare by position. See if your mistakes appear in patterns:

Negative UTG?
not very aggressive button?
small blind spewy?
fold too much against 3-bet?

The GTO Vyve helps transform hand history into practical review: you see hands, positions, actions and leaks in clear language. The idea is not to memorize a perfect table, but to build a better decision-making routine.

Conclusion

RFI ranges are the beginning of well-played pre-flop. Open tight early, press late, respect stacks and review your patterns. When you understand the logic by position, you stop being a hostage of the table and start playing with a plan.
