First hand - Shulman raises 180k, Negreanu calls. comes down - Negreanu check-calls Shulman's 250k bet.
The turn: Both players check.
The river: Check-check one more time, and it turns out that Negreanu's for, as Jack Effel puts it, "A pair of deuces with a large kicker," is good enough to take the first pot.
