1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd6
A fashionable ways to play the Scandinavian nowadays ! 4.d4 Nf6 5.Nf3 a6 6.g3 Bg4 7.Bg2 e6 7...Nc6 8.0-0 0-0-0 is another way to play in this opening. 8.0–0 c6 This move looks like to slow especially after white play 9.Bf4 chasing white queens with a tempo. Probably 8...Nc6 is better. 9.Bf4 white develop with a tempo. Black have to waste time with his queen where as his pieces development , not to mentioned his king safety...is way behind. 9... Qd8 10.h3 Bxf3 11.Qxf3 Be7 The problem with 11...Qxd4 is white will have a strong initiative after 12.Rfd1 whereas black's queen will have to "run" every where to find a shelter 12.Ne2 0–0 13.Qb3 Ra7! I like this move because it's not only guard the b7 pawn, it also move the rook from the attck of white Bf3 bishop. One more idea is after black play b5, his rook on a7 can later go to d7 14.c4 b5 15.Rfc1 Bd6 16.Be5 dxc4 17.Rxc4
Black c6 pawn is weak but he can defend it with 17...Nd5. Black Knight on b8 look passive whereas white could probably double his rook on c file later.
17...Nd5 18.Nc3 Bxe5 19.dxe5 Qg5?! A typical blitz players move. They usually like activities but probably better is exchanging the queen with 19...Qb6 20.Qxb6 Nxb6 21.Rd4 Nd5 20.Re1 Nd7 21.Rxc6! The problem is 21... Nxc3 (21...Nxe5 22.Bxd5 exd5 23.Qxd5) 22.Qxc3 21...Nxe5 22.Bxd5 probably black missed 22...exd5 23.Qxd5 and black will face problem after 23...Re7 24.Re3
h6 25.Rxa6 Qf5 26.Kg2 Qc8 27.Ra4 27.Rxe5? is a blunder for e.g 27... Rxe5 28.Qxe5 Qxa6 27...Rd8 28.Qb5 Rd2?? Bosboom is in serious time trouble ( he has 56 seconds left to reach move 40) which is a typical problem for strong blitz players when playing in longer time control. Probably they think they can play better in time trouble but Bosboom 28...Rd2 cost him a piece after 29.Rxe5 Rxb2 30.Rc5! Rxf2+? a desperate counter play 30...Qb8 31.Qxb8+ Rxb8 and white a piece up 31.Kxf2 Qxh3 32.Ra8+ Kh7 33.Rh5 1-0
