Indian Grandmaster S P Sethuraman crashed through the defences of Russian Andrey Stukopin to score an impressive win and join Yu Yangyi of China in lead on 4.5 points after the end of the fifth round of World Junior Chess Championship.

Stukopin hung in there trying to find some counter play but the Indian came up with a startling manoeuvre to force checkmate after a knight sacrifice.

GM Sahaj Grover outplayed Muhammad Luthfi Ali of Indonesia to jump to joint third spot on four points. Debashish Das and Vidit Gujrathi also moved to four points in contrasting styles.PTI
