Advanced

Definition

Different poker formats have vastly different typical stack depths, which fundamentally changes optimal strategy.

Format dictates stack depth, stack depth dictates strategy

MTT middle 25-50 BB Medium stacks
MTT late 10-30 BB Short to medium
MTT final table 10-60 BB Variable
SNG bubble 10-25 BB Push/fold zone
Hyper-turbo 10-25 BB Always short

Factor Adjustment
Implied odds Matter more

Hand Value Changes

Hand Deep (150+ BB) Medium (60 BB) Short (20 BB)
Small pairs High (set mining) Medium Low
Suited connectors High (implied odds) Medium Low
Big pairs Standard High Premium
AK/AQ Very strong Strong Premium shove
Suited aces Good Decent Shove value

SPR (Stack-to-Pot Ratio)

SPR measures commitment level:

SPR Commitment Level Strategy
>13 Low Can fold big hands
6-13 Medium One pair decisions
3-6 High Commit with TPTK
<3 Very high Can't fold top pair

Formula: SPR = Effective Stack / Pot Size (postflop)

Format-Specific Adjustments

Key Takeaway

Stack depth changes everything. Deep stacks favor speculative hands and postflop play. Short stacks are about push/fold and preflop all-ins. Know your stack depth and adjust your hand selection and strategy accordingly.
