SIXTEENTH-RANKED Austin Jacob Literatus of Davao City upset No. 8 Jiang Tianci of China in the sixth round but struggled to keep pace with the leaders of boys under-14 event in the ongoing Asian Youth Invitational Chess Championships 2010 in Beijing, China Monday.

Literatus, an Asean Age-Group Chess Championships double gold medalist, landed at 16th place with three points he shared with five other players.

Top-seed Girish Koushik of India lived up to his billing by scoring with 5.5 points thus far to grab the solo lead over compatriots Sahoo Utkal Ranjan, Bajaj Prince and Das Sayantan, who took the next three places, respectively.

Ranjan tallied five points while Prince and Sayantan along with China's Wang Dongsen earned four points each.

Literatus stunned sixth-seed Ayan Akhmetov of Kazakhstan in the opening round but lost to No. 32 Rustem Nazarov of Turkmenistan in the second. He split the point with No. 30 Sardor Israilov of Uzbekistan and No. 26 Wei Chao Chu of China in the third and fourth rounds, respectively, only to fall at the hands of No. 18 Fide Master Che Quoc Huu of Vietnam.

He was still playing No. 10 Sumiya Bilguun of Mongolia in the seventh round as of this posting.

The Davao ace has a slim chance of making it through the top five unless he sweeps all his remaining matches. But the highly-touted Indians are strong forces to reckon with considering the way they've been playing in the past six rounds.

RP juniors champion Paulo Bersamino, meanwhile, kept Filipinos' hopes alive as he placed seventh in the boys under-12 with four points. China's Wei YI was on top with 5.5 points followed by India's Karthikeyan Murali and Ghosh Diptayan with identical 4.5 points.

The ninth-seed Bersamino first demolished No. 24 Munkhdorj Enkhdalai of Mongolia then drew with No. 30 Zhuang Hongyu of China but lost to Diptayan.
