Question 1

What is a Push/Fold strategy in poker?

Accepted Answer

When a player's stack drops below 15-20 big blinds in tournaments, post-flop maneuverability decreases significantly. Game theory optimal play simplifies into a binary decision: push all-in or fold.

Question 2

What is the Independent Chip Model (ICM)?

Accepted Answer

ICM converts tournament chip stacks into dollar equity based on the payout structure. Unlike cash games where each chip has linear value, tournament chips diminish in value as your stack grows.

Question 3

What is Bubble Factor in ICM?

Accepted Answer

The Bubble Factor is the ratio between the dollar equity you lose if you bust versus the dollar equity you gain if you double up. A Bubble Factor of 1.5 means you risk $1.50 in tournament equity to gain $1.00.

Question 4

Why does ICM make push ranges tighter?

Accepted Answer

Because chips lost are worth more in real money than chips won near the bubble, players must demand higher equity thresholds before committing their tournament life.

Question 5

How are Nash Equilibrium push/fold ranges derived?

Accepted Answer

Nash Equilibrium represents an unexploitable strategy where neither the pusher nor the callers can improve their expected value by unilaterally deviating from their ranges.
