DAY 156 Opening & Closing

An ideal pawn sacrifice opens lines you want open and closes the ones you don’t.

Now 13 e5 d5! and Black is secure (14 cxd5 xg5; 14 xe7 xe7).

13 d5! exd5 14 fe1

Threatening 15 xe7! followed by 16 xf6.

14...h6! 15 xh6!

Black’s slim chances rested on 15 xh6 e4! 16 f4 d6.

But now 15...dxc4 16 xc4 (threat of xg6+) is strong.

Question 179: Are there good alternatives to 16 xc4 ?

15...g4 16 h4! xg5 17 xg5 f6 18 h6!

Now 18...c8! 19 e3! prepares 20 f3 and xf6.

18...d4 19 e6! e8 20 xg6! resigns.

It’s 20...fxg6 22 xg6+ h8 23 f7 mate.
