David Kim ties for first at the Marshall G/60 with GM Alex Lenderman!

 David Kim (1765, now 1877) went 4-0 yesterday to tie for first at the Marshall G/60, beating NMs Juan Sena and Leif Pressman. Nineteen IS 318 students played. Shawn Swindell and Ed Kopiecki shared the Under 2000 prize with 3/4, and Aleem Awan, Jermaine Cooper, Vaughn Soso, D'Andrea Dey, and Alex Bradford tied with 3 others for the Under 1700 prize.
 The talented 6th grader Brian Arthur (1225) is white here against the experienced and clever 8th grader Jermaine Cooper (1684). Black played the only move, 28....f6. What happens next?

Brian is black here against fellow 6th grader Carlos Tapia (1087). He blundered with 8...Ngf6. How should Carlos have taken advantage?

Mariah McGreen (1446) was black against Michael Mendez (1517). How does she avoid an immediate loss?

1) 1... f6 2. Qxh6+ gxh6 3. Bxf6+ Kh7 4. Rg7+ Kh8 5. Rg6+ Kh7  is a draw.
2) 9. c4! Qe6 (9... Qa5 10. Nd6+ Kd8 11. Nxb7+) 10. Nd4 Qe5 11. Nxf5 Qxf5 12. Nd6+
3) Black has two ways out:  16... Kg7 17. gxh5 Rh8 Now black threatens simply to take on h6, so: 18. h6+ Kg8 19. Nxe6 (19. h7+ Kg7 +/=) 19... Qd7 (not 19... fxe6?? 20. Qxe6+ Kf8 21. Qf6+ Ke8 22. Qxh8+) 20. Ng5 Qxh3 21. Nxh3 and white is better but it's far from over. There is also the strangely simple 16... Qd7, with the idea that 17. gxh5 Nf5 18. hxg6 fxg6 and the 7th rank is covered just fine.
