 APRIL JUDGEMENT: a_random_guyI am *so* happy, tipsy, that you posted that glowing review *after* I had judged your entry! Else people might think I'd favoured you! *grin* Honestly ... thanks. ================================================================= APRIL JUDGEMENT: a_random_guy (1904) as Black vs. jstevens1 (1915) = 0-1  game ================================================================= ECO: D00e [Queen's Pawn: Stonewall Attack] Opening phase (move 1-12): 5 pts. No errors. White is playing a very solid opening. Black is responding well to it. It may be argued, I think, that 3...e6 isn't the best move as it dooms the c8 bishop to passivity for the time being. On the other hand, it is solid enough and still perfectly playable: no penalty. Middle game (move 12-23): 5 +2 +2 -1 +1 = 9 pts. White uses his space advantage on the kingside well, squeezing Black almost as far back as he can go and still be on the board: +2 pts for move 13-16 (I am not convinced that 16.Qh6 is "inaccurate", as GK flags it, to any determinable degree). Black's counterplay (move 16-21), using the holes in White's center, is well executed and worth an additional: +2 pts. He misses a trick with 22...Rc7 however. The alternative, 22...Rxc1, not only gains material, it also smashes open White's defensive structures: -1 pt. Finally, +1 pt for correctly seeing the fork after White's disastrous 23.Nf3. White resigns rather than face 23...Qxe3+, losing the rook. End game (none): 5 pts. Level of play: +2 pts. Total: 21 pts. |

APRIL JUDGEMENT: blitzkov APRIL JUDGEMENT: blitzkov (1841) as White vs. romrychkov (1720) = 1-0 game ================================================================= ECO: A11 [English: Caro-Kann Defence, 3.e3] Opening phase (move 1-10): 5 -1 = 4 pts. The computer flags 4...Bh5 as an error, due to 5.Qb3 Qb6 6.Qxb6 axb6 7.cxd5 cxd5. Based on the evidence I'd say I agree. Being somewhat finicky about opening errors, I am detracting 1 pt: White should have seen the possibility of saddling his opponent with an isolated doubled pawn. Compared with the game continuation - where Black is quite solid - that's definitely preferable. Middle game (move 11-48): 5 +2 -1 +2 +1 +2 +1 = 12 pts. Nice tactical sparring at moves 17-20: +2 pts. Move 24.Rac1 is, correctly, flagged as an error. Black could have penetrated and caused significant grief by means of 24...Qb6 followed by 25...Qxb3: -1 pt. On the other hand I really like Black's play at move 25-29. Good, sound positional play culminating in a very nice combination touched off by 32.Nxf2. +2 pts for the positional play, +1 pt for the combination itself - a very nice touch, even without the optimal continuation. After 32...Nxf2 33.Kxf3 the advance f5-f4 would be very powerful, wrecking open the defences around White's king and bidding fair - if done immediately - to decide the game in Black's favour. Instead Black chose to invade White's soft underbelly - his queenside; also a valid strategy, even if not the best. But even after that, for the next two moves f5-f4 remains an open - and better - option. GK flags 36.h4 as a mistake, but White is in trouble and has to try to create at least the semblance of counterplay. He has no active threats, no avenues of attack or counterplay at all, which means he is dead - unless he does something to create openings he can use. A very good illustration of exactly how powerless White is: Black's nonchalant capture of the pawn on a4 (move 41). Move 44.h5: we see here the point of White's play - the creation of threats around Black's king, first by advancing the h-pawn (move 36), then the sacrifice of the pawn on a4 (move 41) to win time for maneuvering the bishop to e5 (move 43), and finally yet an advance of the h-pawn (move 44) to create active threats which Black must respond to. The whole plan, conceived and executed over several moves and in the face of stark desperation, is worthy of an additional +2 pts. By correct play - simply ignoring the threat for now and continuing 44...a4, Black could have won; the threat is mainly illusionary. But Black stumbles, lured into a tactical miscalculation, and loses a piece - and the game: +1 pt for the combination touched off by 45.Nf2. End game (move 49-59): 5 +2 +1 = 8 pts. Nicely calculated bishop sacrifice at move 51: +2 pts. Good mate: +1 pt. Level of play: +4 pts. White was outplayed for much of the game, despite being at more than +100 pts relative to his opponent, who played masterfully right up to the fatal error on move 44. The points given are based on Black's play and on White's successful creation of counterplay where none existed. For playing an opponent more than -100 pts worse: -2 pts. Total: 26 pts. |

APRIL JUDGEMENT: darknite13 APRIL JUDGEMENT: darknite13 (1968) as White vs. trigon59 (1934) = 1-0 game ================================================================= ECO: C59b [Two Knights: Morphy, Steinitz Variation] Opening phase (move 1-13): 5 +1 = 6 pts. Black is actually playing a gambit variation, sacrificing a pawn for speed of development and better placed officers. Interesting: +1 pt. Middle game (move 13-43): 5 +2 +3 +1 +1 = 12 pts. Black gives up the bishop pair in order to break up White's kingside (move 15), but White competently neutralizes Black's potential there and initializes counterplay against weaknesses in Black's own pawn structures instead (move 16-23): +2 pts. For the very nicely calculated combination, move 24-30: +3 pts. The Black knight on d4 has no good resting place and cannot take part in the defence of the weak pawn on e5. Black exchange it in return for the restraining White bishop on g6, but the way White handles that exchange leaves Black tactically unable to defend the pawn, despite his otherwise reasonably-placed officers. To my mind, it is a very beautiful example of how to utilize a minor advantage in mobility against an enemy weakness. Nice little combination taking advantage of Black's mistake at move 35: +1 pt. Black places the queen on the same file as the king, which gives White a tactical opportunity to demolish his kingside defences. Forcing the queen sac, move 40: +1 pt. End game (move 44-53): 5 +2 = 7 pts. Tactical sparring, move 47-53. Black trying to stop the mobile pawns, White trying to advance them. In the end White sacrifices his queen and pawns for Blacks remaining officers, forcing a simple and won endgame setup. Classic and illustrative: +2 pts. I am not detracting for going with 49.b4 instead of 49.f6. GK flags 51.Qf5 as a blunder, but either variation wins without doubt so no penalty. Level of play: +4 pts. No real blunders and few mistakes in a game with very clear and competent play from both sides, even though Black is outplayed and at a disadvantage very early on. Total: 29 pts. |

APRIL JUDGEMENT: miodrags APRIL JUDGEMENT: miodrags (1396) as White vs. dgregoryn (1409) = 1-0 game ================================================================= ECO: D07f [QGD: Chigorin, 3.Nf3] Opening phase (move 1-8): 5 +1 +1= 7 pts. Black's not-very-good queen retreat, 5...Qd8, is promptly and decisively punished by White: +1 pt. Black's follow-up mistake, 6...Nb4, is likewise responded to with proper immediacy: +1 pt. Middle game (move 9-27): 5 +1 +1 +2 = 9 pts. White's active play with 14.dxe6 earns: +1 pt. I am not penalizing White for choosing 19.Ke2 rather than 19.Ne5; though the knight move is better and preferable, the King move is also good. The next move, 20.Rhe1, is a mistake however, and Black's prompt, tactical response to it earns another +1 pt. White correctly sees that 23...Nxa2 is a mistake, and though he does not quite find the optimal response, the tactics he uses, culminating in 27.Qxc5, earns him another +2 pts. End game (move 28-36): 5 -1 = 4 pts. With 28.Qxc7+ White misses a neat trick: 28.Qc2+ Kg7 29.b3, capturing the bishop: -1 pt. Level of play: +2 pts. Some errors, but relatively quite ok. Black gives up a tad early however. Total: 22 pts. |

>> APRIL WINNER << darknite13 (1968) as White vs. trigon59 (1934) = 1-0 game ================================================================= For an extremely competent and well-executed game, tactically interesting, positionally well-played, and with an instructive end-game as additional bonus. White first neutralizes Black's attack on the kingside, then creates successful counterplay against the holes in Black's pawn position - a result of Black's gambit opening and attack. The quietly beautiful tactics in the middle game are well worth a play-through, and his handling of the endgame is examplary. All in all, a game worthy of the GOM title. |

Thank you Thanks to rmannstaedt for taking time out of his day(s) to analyze all these exciting games. I also should thank my opponent trigon59 for playing such a powerful game against me. (In case anyone is interested, we played to a draw in the 2nd faceoff ). Thanks to all of you for letting me be apart of the club. It's nice to be back in the chess world after the hiatus I took. I don't have anything worth sharing for May, as I had to undergo surgery for a leg broken in 5 places. (Must say that the plate and screws put in are quite painful, and they constantly feel like they are rubbing against the bone.) I finished some games, but most were postponed due to the surgery. I won some games, but they were against lower rated players who made considerable blunders that made it convenient to take advantage. Oh and I have my coaching duties. Recently, the kids I coach won several medals and the 3rd place overall prize at a local event. Next step will be to get them registered and play in some rated tournaments. We'll have to see though who comes around to play in the summer, since school is out and I'm sure no one wants to be at school during their time off I was a child too once. So above all, thanks again to all. Best of luck in future months Ken |

Games not won Of course, the winner may also want to enter the same game - but that hasn't been an issue yet. Not sure if we should decide that the prize goes to the game, or if we should evaluate it twice - once for each player? The schema that some of us use does somewhat depend on which side we evaluate for ... but we'll take that as it comes. In short: enter what games you want - whether won, lost, drawn, hung, or quartered! Only requirements: must be publicly available on GameKnot and must have been finished in the competition month. |

Entry for May...game I admit that, as the analysis shows, it didn't go all my way, and I thought for much of the middle game I would have a tough fight of it to draw. It was a late misjudgment by my opponent that finally tipped the balance in my favour. A hard, hard game. |

(after 14...f5): 15.b5!? Ne5 16.Bxe4!? (16.Bxe5 is safer, but may not give as much) 16...fxe4 (if 16...Nc4 then 17.Bc6+ +-) 17.Rxe4 N7g6 And here I had found 18.b6+! And Black is, I think, lost: 18...Qc6 19.Qxc6+ bxc6 20.Bxe5 Nxe5 21.Rxe5+ Be7 22.Rxa7 +-. The alternative, 18...Qd7, isn't much better: 19.Qxa7 Rxa7 20.bxa7! Qc8 21.a8=Q Qxa8 22.Rxa8+ and White wins. |

damalfi 06-Jun-13, 18:23 |
Well Anyway, with only a quick look: after 19.Qxa7 , black doesn't have to take the rook, he can retreat it to e8. White can take the b pawn, but it gives black more tempoes to try to settle a plan for defence. Still:black doesn't have to shield the king. It may be interesting 18. b6+, Kf7, that shorten a step the two rooks' junction. If 19. f4!?, Bc5+, 20. Bd4! (Bxb6, 21. BxB+), but BxB+, and not 22. RxB (releases the knight), but if 22. QxB, Nc6, 23. f5 (what an interesting position for tactics!). Anyway, once the rooks are joined, the b6 pawn is not necessarily definitory. If white goes 20. d4 instead, Bxb6 and as a minimum, black loses a knigth to 21. fxNe5, but if you look at it, material is equal. Not a lost game. It's a pity it ended so soon! |
