Bad Wörishofen 2010
QGD Semi-Tarrasch
1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.Nc3 c5 5.g3?!
Teske explained after the game he had been trying to transpose into a Tarrasch Defence, but the text is at least dubious and likely bad.
5...dxc4?!
This is the second choice of Stockfish10 and Komodo10 - they prefer 5...cxd4.
6.Bg2 cxd4 7.Qxd4 Qxd4 8.Nxd4

8...Be7?!
Black is behind in development, but it was probably necessary to play 8...a6 to prevent White's next move.
9.Ndb5 Na6 10.Be3 0-0 11.0-0-0?!
White has no need to restore material equality immediately, but even so the engines' suggestions of 11.0-0 and 11.Nxa7 seem better.
11...Bc5?
The engines' 11...Ng4 12.Bxa7 Nc7!? is unclear, but certainly better than the text.
12.Bxc5 Nxc5 13.Rd4 a6 14.Nd6 Rd8 15.Rhd1 Nd3+!?
This is best, according to the engines, which only goes to show what a mess Black is in.
16.exd3 e5 17.Nxc8 exd4 18.Ne7+ Kf8 19.Ncd5 Rd7??
Better is 19...Nxd5, but after 20.Nxd5 White has two minor pieces for rook and pawn, and is likely to win the d4 pawn before long.
20.Nb6 1-0
LESSONS FROM THIS GAME
A bishop on g2 combined with a knight hopping into b5 can be very inconvenient for Black early in the game. But the real key to losing quickly is making tactical errors.
