Lau Can't Improve

Alan Lau was in early position, facing off against a player on the button. Lau first checked the flop and saw his rival fire 6,400, then he check-raised to 19,000. The other player was contemplating his decision for a few minutes and someone at the table called the clock. The floor person gave the player 30 seconds and a verbal five-second countdown and he moved all in for 39,700 with three seconds left to act. Lau double-checked his hand and called.
