Full explanation — Short Stack
A short stack in poker refers to a chip stack that is significantly smaller than the average or initial stack, generally defined as less than 20-25 big blinds (BBs). Playing with a short stack requires a highly disciplined and often aggressive 'push-fold' strategy, where complex post-flop decisions are largely avoided. Instead, players focus on shoving all-in or folding pre-flop, using pre-calculated Nash equilibrium charts or similar tools to determine optimal hand ranges for various positions and stack sizes. This strategy aims to maximize fold equity and minimize the impact of position and skill disparities post-flop, making it a common approach in tournaments and specialized cash games where players buy in short. Effective short-stack play is crucial for survival and accumulation, particularly in the later stages of tournaments.
