| Nov-30-07 | | patzer2: Of course <al wazir>'s (and also Fritz 19's) 21. Qc3!!  sets up overwhelming threats against the weakened castled position, and may be an even better "human" than computer solution to today's puzzle. |
|
| Nov-30-07 | | patzer2: <DukeAlba> You're welcome. I'm glad you like the collection. |
|
| Nov-30-07 | | patzer2: Anyone care to venture exactly where Black went wrong in this game? I'm not a big fan of the early 8...Qb6, as the more solid 8...Nc6 as in F Kuijpers vs Botvinnik, 1963 would appear to give Black better long-term prospects. However, Black seemed to do OK with 8...Qb6 after 9. Be3 Qa5 (declining the poison pawn offer) in Jacimovic vs V Kovacevic, 1989. In any event, White's piece sacrifice 18. Raf1!!, offering the White Knight for an overwhelming attack on the weak castled position, appears to be sound. |

| Nov-30-07 | | newzild: I got the order wrong, playing Rxg7 first, then Nf5.
This is the first one I've missed this week. Much harder, and a very impressive game. |

| Nov-30-07 | | YouRang: <patzer2: Anyone care to venture exactly where Black went wrong in this game? > Good question. It's hard to believe that this could be decisive, but it appears that things started going downhill for black after he grabbed the b2 pawn with 9...Qxb2. Sure, black is up a pawn, but at the cost of burning up several tempos and accepting awkward queen position for the rest of the game. Taking the b2 pawn also reveals that black underestimated how quickly and efficiently white could mount a kingside offensive - all while black's queen is trapped queenside. Here is how things went downhill for black:
<1> 9...Qxb2 - takes pawn, but with costs discussed above. <2> 10...Qb4 - another tempo spent trying to get the queen back into the game. <3> 11. e5! - White begins a sequence that takes control of the center and opens the f-file for his rook. <4> 14. Rf4! - White develops his rook with tempo (attacking bishop). Black must burn another tempo to save the bishop(14...Bd7). <5> 15. Nd5! - White develops his knight with tempo (attacking queen). Black must burn yet another tempo to save queen (15...Qa5) -- and it's STILL awkwardly placed. <6> 16. Nxe7+ - So white gets the pawn back, again with tempo (check). <7> 17...Qd8 - Yes, another tempo burning queen move -- just to return the queen back to her home square! Anyway, you can see that since move #9, white has been developing and black has been shuffling. It's not hard to see why, by move #18, black is terribly underdeveloped and white has a robust attack underway. I would say that Pb2 was poisoned. |

| Nov-30-07 | | GannonKnight: Missed ... I dismissed 21. Nf5 a bit too early. I knew that somehow you had to get the black Bishop out of the way, but I didn't see that way. It looks so easy now ... 4/5 so far ... |
|
| Nov-30-07 | | RandomVisitor: After 9.Be3, best for black is likely 9...Nc6:

| Dec-01-07 | | CaptGeorge: I still new at this, but I missed it. I thought 21.Nf5 Qxe6 refuted N move. Oh, well. |
|
| Dec-01-07 | | patzer2: <You Rang> <RV>, Thanks for the analysis and suggested improvements. |
|

26...Ke8 27. Bc5 Kd8 |
|
| Feb-06-10 | | Figs: What if 21...Nc6, Freeing the rook on the 8th rank, covering the d4 square, and threatening the fork on e5? |
|
| Feb-06-10 | | Chess Carnival: Figs, too slow at this moment. The fork threat is an illusion: 22.Nxg7 Ne5 23.Nxe8 Nxd3 and Rf8 is mate! |
|
| Feb-06-10 | | Figs: I see, thanks Chess Carnival |
|
| Feb-08-10 | | kevin86: I like an attack where the opponent take pieces,but the attack just grown in intensity. |
|
| Mar-21-10 | | donehung: Now thats how you punish a pawn grabber! |
|
| Oct-14-10 | | sevenseaman: Combinations in Boxing, Fencing, Wrestling many other games are attractive but in chess I find them irresistibly alluring. |
|
| Oct-14-10 | | ughaibu: Guess the move score: 49 |
|
| Dec-30-10 | | falso contacto: in this game, white has too many knights. |
|
| Jan-07-15 | | bharat123: An interesting continuation is
25.Qb3+ Kh8 (25..Kf8 26.Bc5+ Ke8 27.Qg8+ Bf8 28. Qxf8) 26.Bxg7+ Kxg7 27.Qxb7 winning the rook |
|
| Dec-17-15 | | Whitehat1963: Truly impressive finish! |

 | | GoldenKnight: 18. N(d4)f5 jumped out at me right away. White did play it later. I don't feel like analyzing it. Can anyone give me an indication if this would work on move 18? It still looks strong to me. Thanks! |
