Lesson of the Week

Take the free pieces

This week's youth chess clubs are looking at the first few moves a game played by two trophy winners at the Winterfest Scholastic. I previously offered a lesson from one of the games submitted in this event on January 24.

In this week's model game, both players engage in a fight for the center. Both use pieces in coordination to create threats. The decisive difference was that White left pieces vulnerable, and Black took the free gifts. The names have been changed.

Santa (754) - Every Good Child (681) [C62]
Winterfest Deer Park, 21.01.2012

1.e4 e5 2.Nf3 d6 3.d4 Nc6 4.Bb5 Bd7 5.Qe2?!

Black to move

5. Nc3, O-O, and even d5 are better.

5...exd4 6.e5? 

6.Bxc6 Bxc6 7.Nxd4 was played in Russia in 2009. See the bonus game below.

6...dxe5 7.Nxe5

It still seems sensible to try 7.Bxc6 Bxc6 8.Nxe5 Qe7 9.Nxc6 bxc6

7...Nxe5 8.Qxe5+ Qe7

White to move


Now Black has a decisive advantage.

White should have tried 9.Bxd7+ Kxd7 10.Qxe7+ Bxe7 or 9.Qxe7 Bxe7 10.Bxd7 Kxd7 both leading to the same position where Black is ahead by one pawn.

9...Bxb5 10.Na3 Qxe5+ 11.Bxe5 Bxa3 12.bxa3 Ne7 13.Bxg7 Rg8 14.Rb1 a6 15.Bxd4 Rxg2 16.Rb4 0–0–0 17.a4 Bd7 18.Bf6 Re8 19.Re4 Bc6 20.Rxe7 Rgg8 21.Re2

If 21.Rf1

Black to move

Black has a pin 21...Rxe7+ 22.Bxe7 Re8

21...Bxh1 22.f4 Rg1+ 23.Kf2 Rg2+ 24.Kf3 Rgxe2+ 25.Kg3 Rg8+ 26.Kh3 Reg2 

A possible finish: 26...Re3+ 27.Kh4 Bg2 28.Bg5 f5 29.Kh5 Rh3+ 30.Bh4 Bf3+ 31.Kh6 Rxh4#

27.Be5 R8g6 28.f5 

28.Bg7 does not save White R2g4 29.Be5 Bg2#

28...Rh6# 0–1
