Lesson
The $13,000 Leak: Fixing an Overly Tight Preflop Range
Preflop Architecture · intermediate · 7 min
Tyler reviews database results to show how preflop leaks can flatten a winrate even when postflop play looks fine. Viewers learn how to use the "won money without seeing flop" filter, compare bb/100 across samples, and respond by tightening up range discipline around GTO preflop baselines.
Key takeaways
- Use a database filter for results without seeing a flop to isolate preflop performance.
- Compare the same preflop metric across time periods; a shift of a few bb/100 can represent a large dollar leak over a big sample.
- If the number gets much worse, suspect that you may be playing too tight and giving up small amounts repeatedly preflop.
- To correct the leak, return to GTO-based opening, 3-bet, 4-bet, call-vs-3-bet, and call-vs-4-bet ranges.
- Adjust those baseline ranges by opponent type: play looser against looser players and tighter against tighter players.
