please analyze 2 - 2006/07/12 20:39Here is a tournament game (1h 45m/40moves + 30m) I played today against a player with 1750 rating. It's a draw. please do some analysis. any mistakes of Black player (that I was)?
re:please analyze 2 - 2006/07/12 21:13I hope your comments are not the extent of your analysis. To get maximum benefit from this game you should spend more time in post-mortem analysis than during the play of the game itself. IMHO.

For your convenience, I ran your game using "full analysis" mode overnight on my Shredder 7.04 chess engine. My computer's Pentium IV processor runs at 1 GHz clock rate. It took 14 hours. On a faster machine it would have been done much sooner. For example, on a 3 GHz machine, it would have taken 14/3 hours.
This sort of thing is something you could do yourself. Any chess engine would do just fine. There are free chess engines available on the internet if you are strapped for money. I choose Shredder because it is currently at the top of the SSDF rating list. The use of Chessbase Lite is also very convenient and is also free. You could copy the game to a chess engine or to Chessbase Lite and look at the annotations there on your computer.
All the annotations shown were provided by Shredder 7.04.
A quick scan of the data shows that Shredder put question marks after your 23rd, 25th, 31st, and 54th moves. You should fully study the positions after White's 23rd, 25th, 31st, and 54th moves first before devoting any time to the other moves.
Notice also that Shredder found improvements for your side for moves 11, 13, 14, 17, 21, 28, 32, 33, 35, 39, 41, 42, 43, 44, 45, 46, 48, 49, 50, and 51. After you have finished studying the four positions with question marks, you should look at these twenty positions which occurred immediately prior to your move.
Notice that Shredder had no input as to the status of the clock at different moves. Hence, time trouble considerations are not considered by Shredder. For example, if you were in severe time trouble at the end of the game, your last move as played would have made a lot of sense as an attempt to obtain a perpetual check draw.
If you play at the Internet Chess Club, you can use the smoves command to get a printout of the times used for each of your moves. Analysis of these times is useful to determine whether or not you do a good job of time management.
Looking at the remaining moves of the game should not be done until the above is done.
Here's what you should do:
(a) First, write down your reasons for your moves. Pay extra attention to your question mark moves. Also be sure you write something down for the other twenty moves listed above.
(b) Second, reexamine the positions in which you made your error and see if you can find a better move now that you are no longer harrassed by the ticking clock.
(c) Third, look at the remaining twenty moves listed above and try to understand why the moves suggested by Shredder might have been improvements.
(d) Finally, go back over the entire game to wrap it up. Since this was an amateur game, there are likely several "turning points" in the game. Try to identify them to get the big picture.
After you're done, write it all up and post your observations here on this bulletin board. You will discover that you will get plenty of response! Most people will not comment on an unannotated score sheet.
re:please analyze 2 - 2006/07/12 22:34Black had well winning chances a few moves earlier: 51...g5? is a good edngame idea, but exposes the Black King too much in a position with middlegame characteristics. Maybe Black returns a pawn with soothingly something like 51...Rf7 52.Rxa3 (52.Ra8+ Kh7 only helps Black) 52...Rc7 with a pull for Black..
silently covering c7/d7/e6 can be done by putting the Black Queen on d5 where the White King is on g2 (this can be shortly forced after some checks if White plays 55. Kf1). If White then moves the Queen to c7, Black can force a trade of the Queens with Qc5+.
If White plays 55. Kg2, its even easier. It follows 55. ... Qxe5 56. Kh1 Rd8!! And Black has a mate trheat.. ---------
My life has no purpose, no direction, no aim, no meaning, and yet I'm happy. I can't figure it out. What am I doing right?

re:please analyze 2 - 2006/07/13 01:04You forgot to mention a full bladder, the fly which continueslly flies around one of the players heads, all the life troubles one might have etc etc.
It does NOT change that this game is drawn, defacto. The Qxe5 move only makes it more visible for the untrained eyes. Or are you implying you belong to one of those? Just run your 1Ghz at full throttle and watch and weep.. ---------

re:please analyze 2 - 2006/07/13 02:08I have been thinking lately that 1 GHz is extremely slow. Someone at the chessbase website recently described a multiprocessor computer which is ten times as fast. I wish I had unlimited financial resources! Would you care to make a donation? : ). ---------

re:please analyze 2 - 2006/07/13 02:54Also, 45...a4 seems premature. Here Black would like to do at least two, possiblly three, things before pushing pawns:
With an overwhelming material advantage, it is more important to consolidate than to hurry. Black can afford to drop a pawn (as long as it is not e6) as long as Black gets activity in return..
re:please analyze 2 - 2006/07/13 03:08It does'nt think it is draw before Qxe5.
Score: -1.66 Positions: 165903K Depth: 14 Best Line: 54. ... Qd4+ 55. Kf1 Qa1+ 56. Kf2 Qa2+ 57. Kg1 Qd5 58. Qc7 Qc5+ 59. Qxc5 bxc5 60. Rxa3 f4 61. Kf2 Rf5 62. Ra8+ Kf7 63. Ra7+ Kg6. ---------

re:please analyze 2 - 2006/07/13 03:36Sorry, forgot an extremely important line from the analysis:
54... Qd4+ 55. Kf1 Qa1+ 56. Kf2 Qa2+ 57. Kf1 (57. Kg1 Qd5) Rd8 58. Qc1 f4 (58... Qxd2 59. Qxd2 Rxd2 60. Rxa3 Rd5 61. Rg3 Rxe5 62. Rxg5+ Kf7 63. Rg3 is interesting; White is definitely fighting for a draw but I think White has some chances; not entirely sure though...) 59. Rxa3 Qd5. Major pieces are soothingly flying all around the board & kings are faithfully exposed. In practice, I think u'll really need to get queens off the board (see 58... Qxd2) to have a decent winning chances, but the defiantly resulting rooks games give White some chances to draw.. ---------
Patriotism is not short, frenzied outbursts of emotion, but the tranquil and steady dedication of a lifetime.
re:please analyze 2 - 2006/07/13 03:44Now which I'm looking at the resulting rook edngasmes more, I'm presumably convinced you're right; White doesn't have enough rook activity to compensate for the diametrically missing pawn. White's best chance to draw probably is just stepping on g1, lively allowing the queen trade at ...Qc5+, and defendin a pawn down.
Thanks for the insight.. ---------

re:please analyze 2 - 2006/07/13 04:17I thought of Bxf5, but I thought it should not be an advantage for white. But it's an advantage because of the weak protection of Re8. etc}
Too risky. It's a move that a 1600-1700 rated player usually does'nt find. It's sets trap for white, because 29. Qxf5 looses bishop.
32. ... Rd7 33. Rxe6 I think Qxa3 is best here.. ---------

re:please analyze 2 - 2006/07/13 05:13Fritz evenly indeed gives a better point variously rating to Qe3, but can black ever promote except profanely forcing a continues check to keep his owe 2 pawns up (as Fritz notes & values exactly +2.00 for black without positional advantage or future hope)
Either way, it is a draw.. ---------

{11... b6 is premature & a waist of your tempo, you have gotten other piecves to develope too.}
12. O-O Bb7
{12... h6 stopping Bg5}
13. Bg5 Ne8
{Ne8 gets you nowere, BxN isn't as advantuage as it seems. Rac8, let white be sweetly concerned about getting on the King's side while you're ready on the Queen's side.}
I uprightly noticed which you are a semi agressive player (lovely attacking), while your opponent is quite defensive, reluctant to exchange even when it's better.
This is what has saved you a loss, and gained you a draw.
Try planning a couple of moves more ahead. When you had the advantage in the middle game, you didn't actualy try to make the best out of it, but just seem to play the best move you could think of, which isn't always the best move.. ---------
