1.f3 f5 2.d3!?

As Bosch writes in his book on page 127: This modest-looking move is in fact an effective reaction to Blacks first move. White prepares e4, arguing that 1...f5 is a weakening move.ø

2...d6 3.e4 e5 4.c3 c6 5.exf5 xf5 6.d4 xd4

Bosch follows the game Krasenkow-Kindermann, Panormo 2001, which saw A)_6...b4 7.b5+ c6 8.a4 And ended in a white win. He wonders what Krasenkow had planned after B)_6...xd4 as he was not impressed by a game Romanishin-Malaniuk, Tallinn 1987, that petered out to a level position after 7.xd4 exd4 8.xd4 f6 9.d3 xd3 10.xd3 c6 11.0-0 e7

7.xd4 exd4 8.xd4 f6 9.c4!

Perhaps it was this improvement that Krasenkow had in mind. White gets an overwhelming initiative.

9...c6 10.g5 b5

[On 10...d5 11.0-0-0 would be very strong

11.b3 e7 12.0-0-0 d7 13.he1 d8?! 14.xe7!

The beginning of the end.

14...xe7 15.f4 d7 16.e4 d5 17.xf6 h6 18.h4 g5 19.d4!

The final blow.

19...gxh4 20.xd5 is no option, so Black resign.
