Yet another improvement

I was looking for improvements on my game last week, where my opponent was baffled by my audacious 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 e6 9.Qf3 Nd5 10.Bb5+ c6 11.0-0.

My opponent choose the inferior 11...f6, but I realised black would get trhe upper hand aftre the correct 11...Nf6, as 12.Rf2 complicates things even further, but black remains on top after the simple 12...Be7.

But now I see that 11.0-0 is in fact the bad move ! 11.Rf1 (diagram) is much stronger.

a/ 11...Qh4+ 12.Kd1
...a1/ 12...cxb5 13.Nxd5 (++)
...a2/ 12...Nxc3+ 13.bxc3 (+=)
...a3/ 12...Be7 13.Nxd5 (+=)
...a4/ 12...f6 13.Nxd5 (++)
...a5/ 12...Qf6 13.Qg2 (=)
...a6/ 12...Qe7 13.Nxd5 (++)
...a7/ 12...Bd6 13.Nxg6 (++)

b/ 11...cxb5 12.Nxg6 (++)

c/ 11...Nf6 12.Be2 (=)

d/ 11...Qf6 12.Nxd5
...d1/ 12...exd5 13.Qxd5 (+=)
...d2/ 12...Qxf3 13.Nc7+ Kd8 14.Rxf3 Kxc7 15.Nxf7 (+)

e/ 11...f6 12.Nxg6 hxg6 13.Bd3 (=)

f/ 11...f5 12.Nxd5 
...f1/ 12...Qxd5 13.Qxd5 exd5 14.Bd3 (+=)
...f2/ 12...exd5 13.Bd3 (+=)

So it seems to me that 11.Rf1 is much stronger than 11.0-0. There is no advantage in sight for black and he will soon be drowning the terrible complications against a well prepared attacker.

Also, black can hold in three lines :
> 11...Qh4+ 12.Kd1 Qf6 Qg2
> 11...Nf6 12.Be2
> 11...f6 12.Nxg6 hxg6 13.Bd3

My next post will focus on these lines.


  1. Hello Sir,
    as i have a little look at this game, while playing the moves step by step i think, iwould go another way in this Nd5 Variation, in the Teichmann. My database, my own Blackmar Diemer Book, give 3 Alternatives: Instead 10. Bb5+, i played some games with 10. Bd3 !?, another Option, is 10. h4 Nd7, 11 Nxg6 hxg6, 12. Nxd5 exd5 13. Be3 Rxh4 14. Bh3 and next Castle queenside. Pair of Bishops, open Position, well development will give Compensation for the pawns. And after watching at this line i found another New Idea with 10. Bc4 !?, after Exchange the Knight on c3 , Queen cannot come to d5. So i think we Blackmar Diemer Players have enough Options to Play aggressive and with own Ideas against this early Nd5 line.

  2. Hey Guido,
