Playing Holdem Poker like a Bookie means calling all overlays and folding all underlays so determining the overlay/underlay cut point is crucial. Online players use online calculators dozens of times every hour to get the overlay/underlay cut points for their pair, flush, and/or straight draw potentials but David Sklansky has shown how it's almost impossible to do in a live game when combining just two features takes 7 steps, three features takes 9. Poker Systems Engineering "TajProfessor" John "Great Canadian Gambler" Turmel has published the Turmel-Two-Step "in-head" calculator for approximating the win/lose cut point in only two steps. No Division, No Multiplication to master the Turmel-Two-Step. The Turmel-Two-Step Holdem Call Odds System Study Course & Exercise Book includes over 15,000 distinct random hands to exercise counting outs. Visit: johnturmel.com
