The heso is the pyramidal cavity carved in the underside of a floor goban.

According to YMI ([1]), the cavity at the bottom of a goban (heso?) has to do with the drying of the goban.

Some say that it also improves the sound quality.

axd IMO, I cannot imagine how such a relatively small cavity in such a big mass of wood can contribute significantly in the sound of a stone put on the goban. But I'm note sure.

"6. Navel (blood reservoir) carving

6. Navel (blood reservoir) carving

When Go was brought to Japan (in the mid-5th century), the boards were made out of boxes, and a hole was cut into the center of the underside to improve the acoustics. The navel is a remnant of this tradition.

The other name for this indentation, "Blood Reservoir", comes from the story of an accomplished samurai's game. One of the spectators offered an unsolicited opinion as to where one of the players should play next, and the furious samurai beheaded him and placed the spectator's head on the overturned Go board, filling the indentation with blood.
