|Dec-31-03|| ||Erwin damar prasetyo: GREAT GAME,fine combination,black mistake is on the move 9)be6?.he should play d5 an then nb4 and fighting for win |
|Dec-31-03|| ||JSYantiss: Black has two problems here....he has to save his queen and prevent 21. Qh5. Logically, he chose to prevent 21. Qh5, as that would have led to mate shortly thereafter. Masterful move by White here. |
|Dec-31-03|| ||patzer2: For today's problem the solution begins with the combined "clearance," and "double attack" move 20. Bb5! This key move (1) clears the d1 to h5 diagolal for the queen to move to h5 and (2) threatens to either capture the queen (21. Bxd7) or mate in three (21. Rxh7+ Kxh7 22. Qh5+ Bh6 23. Qxh6#). Since, Black can't stop both threats in this "double attack," he choses to stop the mate and lose his queen -- with a decisive loss of material to follow after the exchanges.|
Now while the followup 21. Bxd7Q wins with good technique after Black's 20...Bh6, I think I found a quicker and more decisive win for White with 21. Rxh6!
Fritz 8 verifies my calculation, giving best play as 21. Rxh6! Rxg5 22. Bxd7 Nxd7 23. Qxd5 Reg8 24. Ra1 Ne5 25. Rh3 Nc6 26. Qxf7 R5g7 27. Qd5 Nb4 28. Qd2 Nc6 with an even more decisive advantage than the game continuation (+6.75 @ 17 depth @ 745kN/s). Play could continue 29. Qc3 Ne5 30. Rg3 a6 31. Rxg7 Kxg7 32. Rg1+ Kf7 33. Rxg8 Kxg8 34. Qc8+ Kf7 35. Qxb7 a5 36. Qd5+ Kf8 37. Qxa5 with a very obvious win (+9.56 @ 15/51 depth & 773kN/s).
|Dec-31-03|| ||Minor Piece Activity: Hey you guys, can you help me out? I've been gone for a few days, so I missed the last few puzzles, and couldn't put them in my collection. :-( Can someone give me the links for the last 3 puzzles? Thanks! :-) |
|Dec-31-03|| ||chessgames.com: Jan Cervenka vs NN, 2002
Steinitz vs A Hodges, 1891 17. ?
Perez vs Fernandez, 1947 13. ?
|Dec-31-03|| ||patzer2: <Erwin damar prasetyo> I agree with you that there may be a better move than 9...Be6. However, I'm just not quite sure if an immediate 9...d5 is best here, although it does seem to have very good potential.
After 9...d5 10. e5 Qb6+ 11. Kh1 Ne4 12. Nxe4 dxe4 13. Bc4 Bf5 14. Qe2 Qc7 15. Be3 Rfd8 16. Rad1, Fritz 8 indicates White has only a slight advantage (+0.56 @ 16 depth & 504kN/s) and Black's position looks well developed with potential for achieving full equality. Perhaps it is better to play 9...a5 first to prepare 10...d5, which worked well for Black in A Matanovic vs Fuderer, 1950 (note how similar the play is to the Fritz 8 analysis).|
However, I think a better move here may be 9...b5!? as played in the two pretty Black wins in C Jones vs Christiansen, 1977 and N Castaneda vs D Gurevich, 1994 giving Black aggressive counterplay against White's extended pawn center and cramped queen side.

|Dec-31-03|| ||kaptajn4: 15 sec!!
Happy new year everyone.
|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
|Dec-31-03|| ||kevin86: Hey Kaptajn4 5.7685435432 sec,just kidding,
Happy 2004 everybody!!!
|Dec-31-03|| ||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 |
|Jan-02-04|| ||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.
