11 Jan 2026 bluff check-raise exploit ranges Nick Petrangelo and Jonathan Jaffe deliver an advanced masterclass on exploitative poker theory. They analyze player types through hand histories, demonstrate how to identify strategic weaknesses, and show how to construct profitable counter-strategies across all streets. Exploits require deep theory knowledge. True edges come from river decisions and understanding opponent bluff construction patterns. Advanced Exploitative Framework: Soft vs Hard Exploits - Soft exploits adjust frequencies within solver-approved ranges, while hard exploits use completely off-chart hands. Both approaches require understanding equilibrium strategy first. Player Profiling Through Hand Sequences - Analyzing multiple hands reveals strategic patterns. The "range advantage guy" keeps life simple by avoiding check-raises and complex lines, creating massive river exploitation opportunities. Bluff Construction Fundamentals - Players need specific pre-flop three-bet ranges and flop check-raises to have legitimate bluffs on later streets. Missing early node bluffs eliminates river credibility. The Nit With Tricks - Some players appear tight but make "tricky" plays like flatting aces or check-calling premium hands. Recognizing this pattern allows aggressive counter-exploitation when they show weakness. River Decision Making - Elite exploitative play happens on rivers and turns. Understanding what hands opponents needed to continue earlier streets reveals when they're over-bluffing or can be range-folded. Uncomfortable Continues Win Money - Calling with weak hands like low pocket pairs or backdoor draws on earlier streets unlocks massive river bluffing opportunities when turns go check-check. Counter-Exploit Awareness - Every exploit alerts observant opponents. Staying within solver ranges (soft exploits) provides protection against counter-adjustment compared to completely off-chart plays.
