  Touch of Knight: I am still investigating the position after 21…Ne5 22.Bb3 Re8 23.Ka1

Deep Fritz 11, 29-ply (lines 3-4 are 28-ply, after running for nearly 20 hours:

1. (0.16) 23...Qc5 24.Qd2 Kg8 25.Nc2 a5 26.a3 a4 27.Ba2 Rg6 28.Ne3 Rd8 29.f4 Nc4 30.Bxc4 bxc4 31.Qd4 Rc8 32.f5

  Touch of Knight: In the line 21…Ne5 22.Bb3 Re8 <23.Ka1> Qc5 24.Qd2 Kg8 25.Nc2 a5


click for larger view

If White plays 26.a3, then 26…Rd8 is probably better than 26…a4.

26…Rd8 27.f4 Nc4 28.Qd4 Rc8 29.Bxc4 Qxd4 30.Nxd4 Rxc4 31.Rd2, 0.00/25

26…Rd8 27.f4 Nc4 28.Bxc4 bxc4 29.Ne3 f5 30.exf5 exf5 31.Nd5 Rb8, 0.05/24

However, I am suspecting that 26.Ne3 is better for White, and I will take a closer look at that.

  Artar1: Playing <21...Ne5> may hand the advantage to White.

<21.Bc2> Anticipates ...Ne5 and adds influence to the a4-d1 diagonal in defense of White's castled position. I am not surprised that the <GMAN> chose this move; it is the best at his disposal.

<21...Ne5> With the idea of eventually playing ...Nc4.

<22.Bb3> Is recommended by <RV>; f4 is also playable, but is more direct and does not allow White to exchange bishop for knight after ...Nc4.

<22...Qe7> Puts the question to the White queen. After the trade, Black moves the king one step closer to the center, a possible advantage in the endgame. Playing ...Rh8 at some point would also allow the two rooks to connect. <RV>, on the other hand, recommends ...Re8. I think the c-rook is better placed on the half-open c-file where it puts pressure on White's castled position.


click for larger view

<23.Qd2> The queen retreat to d2 is preferable to a queen exchange, and it protects the second rank, principally the g2-pawn should Black play ...Rg6. So far White's kingside attack has not materialized.

<23...Kg8> It would be easy for the position to drift into stagnation.

<24.Nc2 Rd8 25.f4> White still holds the initiative with this thrust in the center.

<25...Nc6>

  Artar1: The line, <21.Bc2 Ne5 22.Bb3 Re8 23.f4>, seems to be okay for Black, but further testing is needed.

It would be interesting to see the outcome if White were to play less assertively, beginning with move 23.

  ajile: 21.Bc2 Ne5 22.Bb3 Nc4


click for larger view

Analysis by Rybka 3 32-bit : 22 ply

Initial eval is deceptive. 22..Nc4 is a logical move which provokes Bxc4 since the Nc4 is agressively posted on White's side of the board.

1. ² (0.45): 23.Bxc4 bxc4 24.Nc2 e5 25.Qd2 Bc6 26.Ne3 Ba4 27.Nf5 Rf6 28.Qg5 Rxf5 29.exf5 Bxd1 30.Rxd1 Qe7 31.f6 gxf6 32.Qh6+ Ke8 33.Qxh4 f5 34.Qf2 Qe6 35.Qa7

Analysis by Rybka 3 32-bit : 18 ply

1. = (0.24): 35...d5 36.f4 e4 37.Kc1 Kf8 38.Qe3 a5 39.Rd2 Qd6 40.g3 Qe6 41.h4 Kg8

This is most likely a draw.

Nov-25-08   crazymate: 21. Bc2 Ne5 22. Bb3 Qe7 23. Qd2 Kg8 24. f4 Nc4

this is the line the Ne5 voters like. bringing their knight to c4. attacking the queen to get to retreat.

Now the move they are expecting after Nc4 is a immediate Bishop takes knight. and b3 is supposedly impossibility. I think Qf2/f5 offers white winning position.

25. Qf2 Qf6 26. f5 Rc5 27.

Nov-25-08   crazymate: perhaps 23.Kg8 is a blunder by the computer. maybe if black plays something else. the position wont be as bad. i have to scroll forward a few moves. and check this.
Nov-25-08   crazymate: crazymate's idea on Ne5..

21. Bc2 Ne5 22. Bb3 Qe7 23. Qd2 g5

g5!! and black's exciting return to the kingside!

24. Nc2 Rd8

Rd8 we secure the d6 pawn.

25. Rf1 Kg8 26. Nd4 Rg6

Rg6 we're going to shove that g-pawn straight down the field.. and break him. backs the g pawn with a rook.

27.Qe2 Qf6 28. Rd2 Qf4

Queen is moving up to F4. she wants to get in on this attack.

29. Rfd1 Rf6 30. Nc2 g4

white's trying hard to break our d6 pawn. Nc2 opens up a attack. and we launch our attack.. g4!

31. hxg4 h3! the move that breaks the bank. it looks like well white is winning 2 pawns. but his g pawn cannot take h3.. that would cause his f pawn to fall. to Nxf.. hitting the rook and releasing black's angry light squared bishop to a discovered hit on e5.

move 44 is a pretty combonation. Qe4+ Queen takes e4. Nd2! forking the king and queen! whoop there it is..

black plays g5. giving away a pawn hoping to slow down the black kingside attack.

32. g5 Qxg5 33. gxh3

A couple of questions. What engine did you use? What was the depth of the search? This info is needed to make results meaningful.

Rybka 3 scores the final position 0.36/18. So there is something wrong with black here.

RV's line has 24. Qe3 but I agree on principle that Qd2 is better. I always start at the end of RV's lines and work back. I'm not sure what black's best 25th move is but at 19 ply, Rd8 isn't in the top two. a5 looks better so far.

  Dionyseus: <edda zeitz> <What is the idea of Re8? What is its rationale? I don't understand this move. >

Perhaps to offer protection of the e pawn so that black can advance a protected d pawn. Here's a line as an example of this:

22. Re2 Re8 23. Bb3 Nf6 24. Qe3 Qc7 25. Bc2 Nh5 26. Red2 Ng3 27. Bb3 e5 28. Nf5 Nxf5 29. exf5 Qd7 30. Bc2 d5 31. a3 Rd6 32. Be4 Kg8 33. Qc5 Ba8 *

  Tabanus: 23.Bb3 Rh5!?

24.Qe3 d5 25.e5 Nd7 <26.f4> must be best, for example

26...Nc5 27.Bc2 g6 28.Bd3 Kg7 29.a3 and black is running out of waiting moves (b5 must be covered), 29...Qc7 30.Bc2 Qb6 31.Red2 etc. (31...Qc7 32.g4!)
