Yeoh Li Tian in Dubai open 2019



Yeoh Li Tian was aiming for his third and final Grandmaster norm at the Dubai Open earlier this month but despite playing very valiantly, the mountain was a bit too high for him to climb at the end. Here are his games from the event. There are good lessons in attack and defence for the amateur chess players to learn from them.

A very instructional game below, which I would term as "the dance of the four knights." Just concentrate on the play after 33...Rxg2+.

Li Tian's game plan was very simple: to beat the lower-rated players while against the higher-rated grandmasters, he was play solidly to draw with them. As such, his full point from Sethuraman, the eighth-ranked player in India and the highest-rated Indian player in the Dubai tournament, came as an unexpected present. It certainly eased his quest towards the third norm.

But here came the first setback: Li Tian had to give back the surplus half-point from playing a grandmaster. Both the fifth and sixth rounds were played in the same day. Whether or not Li Tian was tired from the morning's exhilarating win was debatable but he did not play his usual game in the afternoon. Chopping off the knight with 16...Nxe5 would have been called for. Instead, he had to give up the exchange meekly.

This next game in the seventh round was very interesting. The Vietnamese grandmaster managed to break Li Tian's pawn formation into several pawn islands and mopped them up. In the final position, the draw surprised many but the story came out later that both players had thought that their respective positions were worse off. Running short of time, they agreed on the draw. Later, Li Tian's father, Chin Seng, explained that his son was playing well until around the 60th move. He then tried to win but it was a wrong judgement. As a result, Liem then had a winning position. His play was accurate enough but he blundered with 92...Nc2+. After 93 Kb3, Li Tian was better. Liem realised that and he offered the draw. Li Tian said he was too stunned by the offer, thinking that he was losing, and thus agreed to the draw.

And here was the second setback which proved disastrous for Li Tian: losing against someone who was rated lower than him. At first, there was enterprising play and Li Tian gave up his queen and netted his opponent's rook and pair of knights. Ordinarily, this swap would prove more advantageous for the player with the more pieces but Vignesh made some incredibly strong moves to deny Li Tian's pieces from coordinating properly.

The last round was a do-or-die mission for Li Tian. In order to achieve his third grandmaster title norm, he was required to win this game. So he took the risk. Made an exchange sacrifice and began swarming over Dhulipalla's king. But at the end, there was nothing more than a disheartening draw despite the heroics.
