In Expresso, half your opponents are recreational players making huge mistakes. Exploiting these leaks is the fastest path to profit.
Strategy #1: Never Limp from BTN in 3-Max
This is rule number one, with no exceptions in Expresso. Limping from the button is a mistake because:
You apply no pressure: you enter a multiway pot with no fold equity
You miss free fold equity: an open raise from BTN forces folds from SB/BB 40-60% of the time
Simple rule: from BTN in 3-max, you have two options — open raise or fold. Never limp.
Strategy #2: Play Tighter from SB in 3-Max Than You Think
In SB with 3 players, many beginners defend too wide. The problem:
Calling from SB forces you to play postflop OOP with a short stack — terrible combination
The 3-bet shove applies maximum pressure and forces BTN to make a binary decision
With a stack <15BB in SB, most playable hands become push-or-fold decisions
Strategy #3: Adapt Your Calls Facing Open Shoves
Facing an all-in, your call decision must be based on stack depth, position, and opponent’s estimated range.
Rule of thumb: the shorter the stack, the wider you can call. At 10 BB, call with top 40-50% of hands.
Exploiting Fish Error #1: They Call Too Much
Recreational players have an overly wide calling range. They call with any pair, any ace, and sometimes any face card.
How to exploit:
Iso-raise wide against limpers with any playable hand — they’ll call with worse
Bet more for value: if the fish pays with anything, bet 75-100% pot with strong hands
Reduce bluffs: against a calling station, bluffing has negative EV. Pure value extraction.
Exploiting Fish Error #2: Not Enough Open Shoves
Recreational players are too passive with short stacks. They limp when they should be pushing.
Iso-raise their limps wide — you take pot odds to your advantage
Facing their min-raise, 3-bet all-in with a wide range — they fold too often
GTO vs Exploitative: The Simple Rule
GTO (Game Theory Optimal) is a mathematical strategy that’s unexploitable. But against fish, exploitative play is far more profitable.
Against good regulars: play closer to GTO to be unexploitable
Against fish: play exploitative without guilt. If the fish calls too much, value bet more and bluff less.
In Expresso, the population is often mixed: adapt to each opponent individually.
Summary
Never limp from BTN in 3-max — raise or fold
In SB, prefer 3-bet shove over calling OOP
Against fish who call too much: value bet more, bluff less
Against passive fish with short stacks: iso-raise wide and 3-bet shove
GTO against regulars, exploitative against fish — flexibility is the edge
