NL100 strategy: playing against regulars who study and adapt

What a typical NL100 table looks like

At NL100 almost every opponent knows the preflop charts, the standard sizes and concepts like MDF and blockers. Many use databases of their hands with stats on every opponent, so they are studying you too.

Recreational players are few and highly sought after: when one sits down, the table fills up with regulars. Outside those tables, the game feels like a conversation between players who know each other: each one has a fair idea of what the other does, and the edge lies in spotting who deviates from the baseline strategy and in which spot.

Money also starts to weigh in: one stack is 100 USD, and a bad 5 buy-in session is 500 USD. How you handle that emotionally is part of your strategy.

Priorities and the costliest mistakes at NL100

NL100 mistakes usually come from habits that worked lower down:

1. Using small-stakes exploits against regulars. Betting big only for value, or never bluffing the river, shows up quickly in a database.
2. Sizes that give your hand away. If your big bets are always strong hands and your small ones are always bluffs, a good regular plays perfectly against you.
3. Not planning your stack. Betting the flop without knowing how you get to the river with a sensible size leaves value hands unpaid and bluffs stuck halfway.
4. Trusting reads with a small sample. Five hands do not define an opponent; fifty do not either, in spots that rarely come up.
5. High volume, little review. Playing more hands without reviewing the hand histories of big spots repeats the same mistakes on a larger scale.
6. Playing with money you are afraid to lose. Fear makes you fold good spots and call bad ones out of pride: it is another form of tilt.

Exploits at NL100: with a sample and with care

At this stake exploits still exist, but they take a different shape. The question is not "is this opponent bad?" but "in which specific spot does he deviate from what he should do, and how many times have I seen it?".

• The regular with a high fold to 3-bet. If over a large sample he folds a lot to 3-bets, adding 3-bets with hands like K♥9♥ or A♦4♦ wins chips without needing to see a flop.
• The regular who does not defend against turn overbets. If he folds too much to bets bigger than the pot, an overbet with strong hands and some bluffs with blockers gets the most out of him.
• The regular who rarely bluffs big river bets. Against him, folding medium bluff-catchers is correct even if MDF says otherwise.

NL100 regulars adapt. An exploit that works for you today may stop working next week, so check it against new data every so often.

Preflop adjustments: mixed ranges and 3-bets from the blinds

At NL100 your range should not be transparent. That is why POKER AULA's preflop charts use mixed strategies: the same hand sometimes takes one path and sometimes another.

• BB vs a BTN open with A♠4♠: a mix between a 3-bet to 11 bb and a call. As a 3-bet bluff it has an ace blocker and plays well when called.
• BB vs the BTN with J♣J♦: also a mix of 3-bet and call. If you always 3-bet JJ and always call 99, an attentive regular could read your range from the size of the pot.
• BTN facing the BB's 3-bet to 11 bb with 7♠6♠: call. In position, the suited connector realizes its equity well.
• BTN facing the same 3-bet with A♣5♣: a mix between a 4-bet to 24 bb and a call.

Mixing is not improvising: the frequencies come from the chart, and you deviate from them only with data on a specific opponent.

Postflop adjustments: geometric sizing and c-bets by texture

Geometric sizing means betting the same fraction of the pot on every street so you are all-in on the river. In the typical 3-bet pot (you called 7.5 bb with 100 bb: a 16.5 bb pot and 92.5 bb behind), the fraction for three streets is 65.1% of the pot:

With very strong hands, that plan gets the whole stack in without an oversized bet on any street.

On the flop, texture decides the plan. On dry, high boards like A♦7♣2♠, the opener has the range advantage and a small c-bet with the whole range (a range bet) works. On low, connected boards like 8♦7♦5♣, where the nut advantage is shared, the c-bet becomes selective and bigger, with a more polarized range.

Bankroll for NL100

With 30 to 50 buy-ins of 100 USD, your bankroll for NL100 is 3,000 to 5,000 USD. With the 40 buy-in plan, you move up from NL50 once you have 4,000 USD, and if you drop to 3,000 USD you go back to NL50 with 60 buy-ins.

At this stake the number of buy-ins matters as much as the amount. A session with 5 lost stacks is 500 USD, and if that number affects your expenses or your mood the next day, the bankroll is too tight even if the buy-in count checks out.

If poker is a source of income, keep your living money apart from your bankroll. Cashing out for expenses and leaving the bankroll at 25 buy-ins is one of the most common ways to end up playing under pressure.

What to study to move up to NL200 and which level covers it

NL100 sits squarely in POKER AULA's Professional level (NL50–NL200). To prepare for NL200, the topics that pay off most are:

• Deep stacks: what changes in ranges and in SPR with 200 bb.
• 4-bet and 5-bet pots.
• Squeezes and multiway pots.
• Sample size: how many hands you need before trusting a read or your own results.

The Professional course works through those topics with full hands; Training puts you in frequency and sizing spots with an explanation for every answer, and the Calculator helps with geometric sizing, line EV and variance. You can try it all with 48 hours free. No amount of study guarantees results: variance and many other factors affect what happens at the table.
