SPR (Stack-to-Pot Ratio)
SPR（筹码底池比）
SPR (Stack-to-Pot Ratio) is calculated by dividing the effective stack by the pot size. It's a crucial metric that determines how committed you are to a pot and what types of hands play best. Low SPR (0-3) favors one-pair hands, medium SPR (3-10) creates complex postflop decisions, and high SPR (10+) favors speculative and drawing hands that can win big pots.
Example
Preflop, if the pot is $30 and you have $150 behind, your SPR is 5 (150/30).
