CO 75bb Push Fold
CO 75bb Push Fold
A simplified preflop strategy from the Cutoff position with an effective stack of 75 big blinds where the player’s only options are to push all-in or fold.
Overview
CO 75bb Push Fold is a restricted strategy concept where a player in the Cutoff (CO) position, holding 75 big blinds (bb) effective stack, chooses only between pushing all-in or folding. This approach disregards standard options like raising to a smaller size, limping, or calling, thereby simplifying decision-making. In typical cash games or tournaments, a 75bb stack is considered deep, and players usually employ a wide range of bet sizes. However, this push-or-fold framework emerges in specific contexts:
- ICM Pressure: In tournament final tables or satellite scenarios where chip preservation is critical, the all-in or fold model can approximate Nash equilibrium ranges even at deeper stacks.
- Training Drills: Coaches may assign push-fold exercises for the CO position at 75bb to teach students about range construction and opponent reactions.
- Solver Studies: Some solver outputs (e.g., from Hold'em Resources Calculator or MonkerSolver) include push-fold solutions for deep stacks to isolate all-in dynamics.
Strategic Implications
At 75bb, a CO push range is typically tight—around 20–30% of hands—because a large all-in bet risks too many chips. The fold range includes marginal hands, small pairs, and suited connectors that would normally be raised. This simplified strategy loses value from post-flop play but can be exploitative against opponents who fold too often or call too loosely.
Limitations
Push-fold at 75bb is suboptimal in many situations because:
- It forgoes the ability to play multi-street poker, losing implied odds from strong hands.
- It lacks adjustment to opponent tendencies such as 3-bet frequency.
- It does not account for the stack-to-pot ratio (SPR), which is high at 75bb.
Despite these drawbacks, the concept serves as a useful abstraction for studying range sensitivity and all-in equilibria in deep-stacked scenarios.
Related Tools
Players often consult push-fold charts from solvers or databases, but these typically target short stacks (<15bb). For 75bb, custom simulations are required.
