Congrats to Irina Krush and Fabiano Caruana for winning individual silvers and Jennifer Yu for winning individual bronze! #BatumiChess2018
10.Qd2
An interesting novelty by Ding Liren.
Normally White plays 10.Be3 and attempts to create one of the following setups:
A) Be3-Qd2-Rfd1
B) Be3-Qc1-Rfd1
C) Be3-Qc2-Rad1
10...O-O 11.Qf4 Rb8 12.Nc3 f5 13.Qg3 Kh8 14.Rd1 Nb4 15.b3 cxb3 16.axb3 a6 17.Bc4 1-0

30.Ne1!
A strong knight retreat by Parham in order to play h5 or in some cases e4.
30...Bf6 31.h5 Qg7?
A mistake. Now Parham fully exploits the situation.

An exchange sacrifice that quickly wins two pawns in return.

19... Nc6?
A carelessness. Stevic should have continued with 19...Kg7 or even 19...Qxd7. The Black's king will now be under a huge attack by the enemy pieces.
20.hxg6 hxg6 21.Qd2!
A powerful retreat to join the attack!

13.Be2! [There is an important difference between the knight on e5 and the knight on e4. The white knight has been placed on a permanent outpost but the black knight can be forced to evacuate after f3. With 13.Be2, White tries to launch this plan.]
