Go, the strategy game invented in China more than 2,500 years ago, is known for its simple rules and parity. Two players alternately place black and white stones on a grid, with the simple objective of winning a larger portion of the board.
But as any Go player will testify, it may be the most complex of games, involving constant reading ahead, plotting and strategising.
So the set of Go that US President Barack Obama bore as a gift for President Hu Jintao last week may symbolise, to a certain degree, the character of Sino-US relations over the coming years.
Two of the world's greatest powers have finally sat as equals at the same table, in a relaxed manner. But they will be involved in constant manoeuvring to capture or save stones, always mindful of the overall board.
To a visibly annoyed White House, the overseas media focused on how Obama was 'harmonised' by the mainland leadership, accusing the US president of shying away from conflict and failing to gain concessions on key issues such as the currency and Iran's nuclear programme, while appearing weak on human rights.
For many overseas analysts, the much-hyped joint statement issued after the Obama-Hu meeting was more of a bland summary of issues, lacking substance.
