and i believe white has the upper hand

May-23-06  kellmano: What about opening with ....Nd5 instead?The knight will turn out to be annoying for white whether it is taken or not. 10. g5 Nd5. What was your plan then?
May-23-06  aginis: how about
10...Nd5 11.Ncxd5 ed (cd) 12.Nxg6 fg Bd3 Qf6 c3 looks strong for white
May-23-06  dakgootje: <and i believe white has the upper hand > Doesnt Qh1 at least temporairly saves? eg 16. ...Qh1 17. Ke2 Ke7 and black is out of the pin with its king and has a little threat with g6 attacking the pinned knight. Besides that whites other knight and rook cant do much either as the knight is also pinned by the same black queen. so white cant attack immediately either. Cant really see any better moves in your already given line, but im not very sure white is so much better, even though he has an edge
May-23-06  kellmano: Sorry, i meant 11. g5 Nd5, then there is nothing on g6 for the knight to take.
May-23-06  aginis: 16...Qh1 17.Ke2 Ke7 18.Rc1! g6?
19 Nf2 Qh2 (19...Qh4 20.Rh1 ; 19...Qg2 20.Nf4! Qg3(f3) 21.Rh3 Qg5 22.Nd5+ ; 19...Qf3 20.Nf4 and 21.Rh3 is unstoppable.) 20.Bg5+ f6 21.Bxf6+ Kf7 22.Bxe6+ Kxe6 23.Ng7 Bxg7 24.Rxh2 Bxf6 Re1+

16...Qh1 17.Ke2 Ke7 18.Rc1! Nd7 19.Nf2 19.Nf2 Qh2 20. Rh1 Qd6 (c7) 21.Kc3 leaves lots of attacking chances for white.

Jan-29-07  notyetagm: 29 ... f4! is a nice tactical shot by Flohr.

Position after 29 ... f4!:

The point is that 30 ♗xf4?? creates a second <LOOSE> piece: the White f4-bishop would then be one attacker (Black f8-rook), one defender (White d2-queen) <LOOSE> (only a piece defender), while the White a1-rook is <UNDEFENDED>. Black would then play the <DOUBLE ATTACK> 30 ... ♕e4! against these two <LOOSE> pieces.

(VAR) Position after 30 ♗xf4?? ♕e4!:

Black threatens both 31 ... ♕x♗ and 31 ... ♕x♖+. The only way for White to meet both threats is by playing 31 ♖f1, moving his h1-rook away from the Black queen while adding a second defender to his f4-bishop.

But in moving his h1-rook to f1, he has created a <PIN> down the f-file. Black then simply piles on this <PIN> with 31 ... ♗c7, winning material.

(VAR) Position after 30 ♗xf4?? ♕e4! 31 ♖f1 ♗c7:

29 ... f4! 30 ♗xf4?? ♕e4! <double attack> 31 ♖f1 ♗c7 <pinning theme>
