按钮位15大盲注全下或弃牌（BTN 15bb Push Fold）

Overview

BTN 15bb Push Fold is a common simplified strategy in poker tournaments, applicable when the stack depth is around 15 big blinds and you are on the button. The core of this strategy is that the player no longer makes standard raises or calls, but instead chooses to go all-in or fold based on hand strength and opponent ranges, to maximize expected value and reduce complex decisions.

Strategy Background

In the later stages of a tournament, the blind-to-stack ratio increases, raising the cost of mistakes. When the stack depth drops to around 15BB, a standard raise (typically 3-4BB) consumes a significant portion of the stack, and there is limited post-flop maneuverability. Shoving all-in puts pressure on opponents to call, thereby exploiting fold equity to gain profit. The button position offers positional advantage and allows acting first, making this strategy more effective.

Typical Application

• Shoving Range: Usually includes strong hands (such as TT+, AQ+) and some speculative hands (e.g., small pairs, suited connectors), depending on the opponent's calling range.
• Folding Range: Weak hands like 23o, T2s are folded directly.
• Adjustment Factors: Opponents' calling tendencies (loose or tight), stack sizes of the blinds, ICM pressure, etc. For example, if the small blind and big blind have tight calling ranges, you can widen your shoving range; conversely, tighten it.

Mathematical Principles

The Push Fold strategy is based on game theory optimal (GTO) range calculations. A typical example: With BTN at 15BB, if the small blind and big blind have calling ranges of about 20% and 25%, BTN can shove approximately 40% of hands (including all pairs, A-high hands, suited connectors, etc.) with positive expected value. In practice, adjustments are made using software or experience.

Notes

• This strategy is a simplified model; actual play should consider opponent types, dynamics, and tournament stage.
• When reliable post-flop skills are present, mixing in standard raises can sometimes be better.
• 15BB is not an absolute boundary; a range of 10-20BB can be referenced with adjustments.
