- Person 1 (short stack) is sitting to the right of person 2 (deep stack)
- Player to the right of Person 1 raises preflop
- Person 1 shoves all in
- Person 2 shoves all in
- Every other player folds, including the blinds and the initial raiser
- Person 1 shows a KQ suited
- Person 2 mucks his cards without even looking at the turn and the river
