GGPoker regs fold to 3-bets less than the solver

The short answer

Good 3-bet %: about 10–11% vs a single open — the solver 9.9% at GGPoker NL50, 10.5% at PokerStars NL500.
By position: 5% (big blind vs an early open) to 18–24% (big blind vs the small blind).
Regs’ mistake: the big blind 3-bets too little, the button a little too much — in both rooms, at every stake.
Good fold to 3-bet: about 65% on GGPoker, 57–59% on PokerStars. GGPoker regs call too much; PokerStars regs fold about like the solver.

Your 3-bet % is the share of the opens you faced that you re-raised; your fold to 3-bet is the share of the 3-bets you folded after opening. A HUD adds every seat into one number. We measured both the way you play them — one seat against one other — on GGPoker and PokerStars at NL50, NL200 and NL500, for everyone at the table, the regs, the winning regs and the solver. Pick the room and the stakes on any figure: every figure follows.

Early and middle seats: about 7–10%.
Button vs cutoff: 10.6% at GGPoker NL50, 11.3% at PokerStars NL500.
Big blind: about 5% vs the lojack, 13–15% vs the button, 18–24% vs the small blind.

Why so wide? The later the open, the wider the range behind it, so the more of it you can attack. The big blind is the extreme case: against a tight early open it mostly calls with its discount; against the small blind’s very wide open it 3-bets almost one hand in five — and one in four at PokerStars NL200, whose solution 3-bets smaller. That is why the same 10% can be tight from one seat and loose from another.

Where regs get it wrong

The big blind 3-bets too little, the button a little too much.

Big blind vs small blind: regs 14.8%, solver 18.3% (GGPoker NL50); 18.3% vs 23.6% at PokerStars NL200.
Button vs cutoff: regs 12.3%, solver 10.6% (GGPoker NL50).
Small blind: within a point or two of the solver.

The big blind is red in every column, in both rooms, at every stake: regs defend it by calling where the solver 3-bets. The button is teal against every opener: regs attack the cutoff and the hijack more than the solver does. Both gaps are small next to the big blind’s against the small blind.

Do winning players 3-bet more?

Yes, a little — in both rooms, at every stake.

PokerStars NL500: 11.7%, 11.0%, 10.5%.
Big blind vs small blind: the winners 19.2% at GGPoker NL50 — where regs leave the most on the table.

The winners close most of the big blind’s gap and keep the button’s extra 3-bets. These numbers show what winners do, not that 3-betting more is what makes them win: their 3-bets come with everything else they do.

GGPoker: the solver folds 66.8% (NL50) to 64.5% (NL500); regs 59.8% to 56.4% — they call too much.
PokerStars: the solver folds 59.3% at NL200, 56.6% at NL500; regs 57.7% and 56.7%.
Widest gaps: GGPoker openers facing a small-blind 3-bet, 13–17 points.

The two rooms’ solutions are solved with each room’s rake, and the rake is the difference: GGPoker’s cap is higher, and it rakes 3-bet pots even when they end before the flop. With more rake, calling a 3-bet is worth less, so its solver folds more. GGPoker regs fold about as often as PokerStars regs — which is right on PokerStars, and a leak on GGPoker.

3-bet % and fold to 3-bet, by room and stake

Higher stakes: a little more 3-betting, a little less folding.

Room · stakes	Regs 3-bet	Solver 3-bet	Regs fold to 3-bet	Solver fold
GGPoker NL50	9.7%	9.9%	59.8%	66.8%
GGPoker NL200	10.5%	10.1%	59.4%	65.5%

PokerStars NL200	11.0%	11.0%	57.7%	59.3%
PokerStars NL500	11.0%	10.5%	56.7%	56.6%

From NL50 to NL500 the solver folds less to 3-bets as the rake cap falls, and regs 3-bet a little more. PokerStars NL50 has no solver column: Pokalab has no PokerStars NL50 solution yet.

What the guides say

Their 55% fold to 3-bet is right for PokerStars, too low for GGPoker.

Source	Good 3-bet %	Good fold to 3-bet
Poker Copilot	5–9% (low stakes)	~55%
PokerStrategy	—	~55%
VIP-Grinders	8–12%	55–60%
Solver, PokerStars NL500	10.5%	56.6%
Solver, GGPoker NL500	9.9%	64.5%

The guides give round numbers with no sample behind them, and they were written for PokerStars-style games. There they hold up: at PokerStars NL500 the solver folds about 57% to a 3-bet. On GGPoker the same spots call for about 65% — a player who follows the guides there calls 3-bets too often.

Reading your HUD’s 3-bet %

Your HUD mixes seats and squeezes: split it before you compare.

It counts squeezes — 3-bets over an open and a caller. The figures here do not.
It adds every seat — a 10% total can hide a 15% small blind and a 6% big blind.
It counts the opens you faced, not your hands — that is the sample that matters.

To compare yourself with this article, filter your HUD or tracker by position against a single raiser: big blind against the small blind, small blind against the button, button against the cutoff — the spots where regs differ most from the solver — and read them for the room you play.

How to use it

On GGPoker, value 3-bet wider; everywhere, expect fewer big-blind 3-bets.

GGPoker regs call your 3-bets too much — 3-bet a bit wider for value, bluff a bit less.
Open the small blind with confidence — the big blind 3-bets it less than the solver would, in both rooms.
From the cutoff, expect button 3-bets — regs 3-bet it more than the solver.
Read your spot live in MDA Explorer.

Judge your own numbers seat by seat and room by room, and give them a sample: after 100 opens faced, a 3-bet rate of 10% is known to about ±6 points; after 1,000, to about ±2.

Questions

What is a good 3-bet percentage?

Against a single open, about 10 to 11% overall in 6-max: the solver 3-bets 9.9% at GGPoker NL50 and 10.5% at PokerStars NL500 over the spots regs face. By seat it runs from about 5% (big blind against an early open) to 18–24% (big blind against the small blind).

What is a good fold to 3-bet?

It depends on the room. The solver folds 66.8% on GGPoker at NL50 and 56.6% on PokerStars at NL500. GGPoker regs fold 6 to 8 points less than their solver; PokerStars regs fold about as much as theirs.

Is a 12% 3-bet too high?

Overall it is above the solver at every room and stake we measured. In the right spots it is normal: the solver 3-bets 12.8% from the small blind against the button at GGPoker NL50, and 18.3% from the big blind against the small blind.

Do winning players 3-bet more?

A little, everywhere: 10.6% against 9.7% for regs at GGPoker NL50, 11.7% against 11.0% at PokerStars NL500. The biggest difference is the big blind against the small blind.

How many hands until my 3-bet % means something?

Count the opens you faced, not your hands. After 100 of them, a 3-bet rate of 10% is known to about ±6 points; after 1,000, to about ±2.

What we measured

3-bet % — the share of single opens (everyone before folded) that the player re-raised, all-ins included. Squeezes are not counted.
Fold to 3-bet — the share of 3-bets the opener folded, everyone else folded.
Games — real-money 6-max cash, no ante, 80–120bb, GGPoker and PokerStars at NL50, NL200 and NL500; 146,310,961 decisions of regs in all, from Pokalab’s database of 364M real hands.
Regs — the REG family (player types); winning regs — the Top Regs, top 10% by all-in EV winrate among players with 50,000+ hands at that room and stake.
Solver — the Pokalab preflop solution each spot loads, 100bb, 2.5bb opens, solved with that room’s rake and cap (GGPoker’s preflop 3-bet rake included); PokerStars NL200’s solution uses smaller 3-bets. No PokerStars NL50 solution yet.
Sample — a population figure is shown only with 400+ decisions. Read from MDA Explorer, the same queries the app runs, on October 25, 2026.

What this does not say

Single-open spots only — no squeezes.
Winning regs are chosen by winrate — some ran well; their numbers are averages, not a recipe.
Sizes differ — the solver uses one 3-bet size per seat, the pool many.
6-max, 80–120bb, no ante only.
