Description
A Course Built Purely Around Beating Weak Players
Most cash game content teaches you how to play “correctly.” This one teaches you what to do once your opponent isn’t. Doses of Blue Line is a 37-video Saulo Costa module dedicated entirely to recreational-player exploits — the specific mistakes fish, whales, and overly loose, passive opponents actually make, and exactly how far to deviate from balanced play to punish them.
It’s one third of a color-coded system: this volume is built for fish, Doses of Red Line is built for tough regs, and Doses of Green Line is the opponent-neutral heuristics course the other two are measured against. Running one blended strategy against both fish and regs is itself a leak — the correct bluff frequency and value-bet sizing against a station who never folds looks nothing like the correct line against a disciplined reg who punishes over-aggression.
What’s Inside
- 37 lessons and 2 companion spreadsheets, starting with a framework video on how recreational players deviate from solid baselines
- SRP and 3-bet pot lines, in position and out of position, built around fish-specific calling and folding tendencies
- A full block on multiway pots — sizing, bluff frequency, and overbluff spots that most cash content skips entirely
- Preflop range adjustments for opening wider against a known whale and tightening against a tight recreational player in the blinds
Who Should Take This Course
Regulars who already play a solid, balanced game but keep facing soft lineups without a plan for attacking them specifically. If your winrate is being capped by opponents who simply don’t play back at you, this is the course built to close that gap.
Common Questions
What’s the actual difference between this and Doses of Red Line or Doses of Green Line? Green Line gives you the non-opponent-specific baseline. Blue Line and Red Line each take that baseline and show you the correct deviation for one opponent type — fish here, tough regs in Red Line.
Will this make sense if I’ve never node-locked a solver myself? Yes — Costa walks through the reasoning on video, so you don’t need any solver background going in. If you want to dig into the raw GTO trees these exploits deviate from, the Saulo Costa PIO Pack is a natural companion purchase.
Frequently Asked Questions
Do I receive a physical product or a digital file?
Everything is delivered digitally. Once your order clears, you get an instant download link to the full video course and spreadsheets — no shipping, no waiting.
Is Doses of Blue Line too advanced for me?
It assumes you already understand basic ranges and postflop fundamentals, since it focuses specifically on the exploit layer on top of that foundation rather than teaching the basics from zero.
