PW[Shi Ding'an]PB[Fan Xiping]DT[c. 1739]EV[Ten-game Match]PC[Tanghu]US[GoGoD95]AW[pd][dp]AB[dd][pp]C[Fan Xiping was born in 1709 in Haining, China. Just a year later Shi Ding'an was born in the same town, and these two were to become great but friendly rivals.

The father of Fan Xiping was addicted to go and brought the strongest players from all over China to teach his son. By the age of 12 he surpassed all his teachers and went on to become one of the all time Chinese strongest players. 

Let's see a master game between these two boys.]
