Adhiban stole the thunder showing determination and skill to hold a difficult position against Fier.
It was a Four Knights opening by Fier that gave excellent position to the Brazilian as white but he soon crumbled impatiently while going for a quick checkmate with a piece sacrifice.
Adhiban digested the extra piece with remarkable ease and proved that white`s attack was only optical.
Sasikiran went for the trusted Breyer defense as black against Karjakin and the Russian could not do much despite having the experience of playing at the top level. The game was drawn in just 23 moves.
