Dec-31-03  noone2: noone2: Erwin / patzer2

I do not think 9...Be6 is an error, but I really dislike 11 ... Qe6 + wasting a check and putting the Q in a poor spot.

Instead 11 ... Nfd7 looks interesting(the Black B is very powerful - and black has the great e5 post)

If 12 Nd5 e6 and black's position is extremely active

  patzer2: <noone2> White stands better after 11...Nfd7 12. Be3 (white develops for better position after black moves a developed piece twice), while 11...Qb3+ (best move for Black in the position) 12. Kh1 Qd4 completes development and equalizes.

Black's loss was not contributed to by 11...Qb3+, but was caused by a series of inferior moves after that (such as failing to play 12...Qd4).

Jan-01-04  euripides: Does Back hold after 18...Nxd5 19 ed Qc5 ? There are some counterattacking possibilities on the g-file and the back rank.
Jan-01-04  pim: Euripides, your suggestion 18...Nxd5 19 ed Qc5 looks good. After 20 Rh4 Rc8 (just to make a suggestion) I don't see a real way for white to continue to attack and grabbing black's central pawns with 21 Be7: Qc2: 22 Bd6: Qd1: 23 Bd1: Rc1 doesn't seem to lead anywhere for white.
Jan-01-04  euripides: Pim - thanks. Another possibility is 20 Rh4 Bf6 21 Bxf6 ef with a good game for Black. Or 20 Bb5 f6 and I think Black can cope with the threats.
Jan-02-04  noone2: <patzer2> I disagree with your very brief analysis (can you check if Fritz concurs?)

On 11 ... Nfd7 12 Be3 Nc5 (with pressure on the e-pawn - black looks at least equal.

On 11 ... Qb6ch 12 Kh1 Qd4 13 Qe1 Nb4 14 Ra4 a5 15 Bb5 looks good for white due to black's exposed Q. And if instead 14 Qe1 N:e4 14 Ra4 Nb4 15 Nb5 (wins outright 15 ... N:c2 16 R:d4 N:d1 17 R:e4 ).

There are many times when moving a piece twice (or more) in the early stages of a game is fine (aka Alekhines defence, Scandanavian defence, Poison pawn variation of Sicilian, Petroff's defence etc.). Not moving a piece in the opening is a rule of thumb; you should consider carefully before "violating" it - but if there is a counter reason then of course it is ok (just like a sac of a piece is not really giving away material)

Jan-02-04  noone2: <euripides> and <pim> black does look better after the line you suggested. I would suggest that white's 13 g4?? is bad. He should play 13 Bg5 with a slight edge

  patzer2: <noone2> After taking a deeper look, I'll have to agree with you that 11...Qb6+ is perhaps suspect. After 11...Qb6+ 12. Kh1 Qd4 13. Qe1 Nb4 14. Ra4 <14...Qc5> 15. Qd1 Nd7 16. Nd5 Nxd5 17. exd5 gxf5 18. Rc4 Qa5 19. Rf4 Qc5 20. Rxf5 Ne5 , Frisk 8 gives White a clear advantage with 21. Rh5 (+1.28 @ 13 depth & 654kN/s, based on a move-by-move analysis by Fritz 8).

After, 11 ... Nfd7 12 Be3 Nc5 13. Bc4 a6 14. Qe1 white still has a slight advantage per Fritz 8 (+0.56 @ 12/38 depth & 690 kN/s), and perhaps a deeper analysis will reveal better chances than in the 11...Qb6+ variation.

You may wish to purchase Fritz 8 yourself in order to look at more possibilities here.

My own preference would be to look for improvement earlier in the opening with 9...b5!? as in the two games cited above.

Oct-12-04  Whitehat1963: Awesome game. Great example from the player of the day.
Dec-19-21  Brenin: The main theme of White's attack is clear: play Rh4 (attacking h7), exchange the defending N on f6, play Bb5 to attack Black's Q and (more importantly) clear the Q's route to h5, and then play Rxh7+ followed by Qh5+ with threats against the exposed K. The problem is to get these moves in the right order, and to prevent Black from interfering too much with the plan, or at least, to ensure that if he does it costs him material. Exchanging the N first would allow recapture with the B and then Rg7, defending h7, so I would start with 19 Rh4, as in the game, and then adapt the plan depending Black's response. Rabinovich's removing the defensive N himself with 19 ... Nxd5 seems very obliging (and after exd5 may allow the R on a4 to join the attack), so 20 Bb5 comes next. I haven't convinced myself that White is winning in all lines, but OTB I'd try it and hope. At least, 19 Rh4 costs nothing.
Dec-19-21  mel gibson: I saw 2 lines of attack:
19. Bh5 or
19. Rh4

The first line doesn't work.
But I failed to see that Black's Queen would be lost in the 2nd line.

Stockfish 14.1 says:

19. Rh4

  raymondhow: No solve for me. I was somewhat on the right track, figured Bb5 and Rh4 would be involved.

  OhioChessFan: Wow. Might have solved it if I'd stuck with it for an hour. Or two.
Dec-19-21  EasilyConfused: I think 19..Nxe4 partially salvages the situation at the cost of losing a minor piece for two pawns. I think White�s best response is 20 Ra4xe4 to prevent Nf2+ forking the Queen, but this allows Qxf5 bolstering the Kingside defense. Of course a disadvantage is this allows White�s Rook on a4 to join the attack.

  agb2002: White has the bishop pair for a bishop and a knight.

White has Rxa7, Bxf6 (with the idea 19... Bxf6 20.Nxf6 exf6 21.Rd4 Rd8 22.c3 followed by Qd2, Rf1 and Rd1) and Rh4 (with the idea of getting rid of the knight on f6 followed by Bb5 and Rxh7+).

19.Rh4 seems to be most promising:

A) 19... Nxd5 20.Bb5 Qxb5 21.Rxh7+ Kxh7 22.Qh5+ Bh6 23.Qxh6#.

B) 19... a6 20.Nxf6 Bxf6 21.Bb5 Bxg5 (21... Qxb5 22.Rxh7+ Kxh7 23.Qh5+ Kg7 24.Qh6#) 22.Bxd7 Bxh4 23.Bxe8 Rxe8 24.Qd5 is winning.

C) 19... Rfg8 20.Qf1 looks very good for White. For example, 20... Ng8 21.Qh3 h6 22.Bxh6 Nxh6 (22... Bxh6 23.Rxh6+ Nxh6 24.Qxh6+ Kg8 25.Rh1 wins) 23.Rxh6+ Kg8 24.Ra1 f6 25.Rg1 Kf7 26.Rxg7+ Kxg7 27.Rh7+ Kg8 28.Rh8+ and mate next. Or 20... Nxd5 21.exd5 Ra8 22.Qh3 Rfc8 23.Rxh7+ Kg8 24.Rxg7+ Kxg7 25.Qh6+ Kg8 26.f6 and mate next.

D) 19... Qc8 20.Qf1 with the same ideas as in C.

Dec-19-21  AlicesKnight: I was with <raymondhow> in seeing the h-file attack and the Bb5 decoy but not the detail, and was at first surprised that Black took the N as he did, but looking again I take the points made above by my superiors about the choice of preventing mate or conceding the Q. The final f6 touch is lethal; either R move concedes fxe7 (if ...Rc7 then Qe4+ first) and the R goes to stop a new Q - how far ahead was this seen?
Dec-19-21

  Teyss: <OhioChessFan> Or three. And then still miss it.
Wow, just beautiful.

At the end of course if 28...Rd8 29.fxe7 Re8 30.Qd7, or 28...Rc7 29.Qe4+ and 30.fxe7, so Black has to try 28...e6 29.dxe6 fxe6 30.Qe4+ and 31.Qg6(+) (better than Qxe6+ Rf7 which still wins though) with the threats Qxh6, Qe8+ and f7.

Dec-19-21  Stanco: I found it's 19.Rh4 having in mind the idea of Bb5 bringing the queen in action. White threatens to take Nxf6 and eliminate h7 defender, i.e. 19.Rh4 Rd8 20.Bb5 Qb5 21.Nxf6 etc...
Dec-19-21  ndg2: While I saw Bb5 as a potential threat I didn't manage to make it work in combination with a king side attack, so fail for me.
