Apr-29-11  newton296: I only considered e6 as a winning chance but black can defend everything it seems. after 10 minutes of searching for a win I figured I must be missing something and checked with houdin. can someone show me how white wins this? the position is basically dead even with best play?

Analysis by Houdini 1.5a w32: d=22

1. = (0.23): 1.Qd2 e6 2.Qf4 a5 3.Be3 Qc7 4.Qg3 h6 5.h3 a4 6.b4 cxb4 7.cxb4 g5 8.Qg4 c5 9.bxc5 Bxc5 10.Bxc5 Qxc5 11.Nd4

2. = (0.11): 1.e6 Bxe6 2.Rxe6 fxe6 3.Ne5 Qb8 4.Qh5+ g6 5.Nxg6 hxg6 6.Qxh8 Kf7 7.Qh7+ Bg7 8.Bh6 Qg8 9.Qxg7+ Qxg7 10.Bxg7 Kxg7 11.Re1 Rb8 12.b3 Kf6 13.f4 Rh8 14.g3 Rh5 15.Kg2 Rf5 16.Kf3 e5 17.Rxe5 Rxe5 18.fxe5+

houdinin gives e6 as the second best move actually! lol !

Apr-29-11  scormus: <goodevans: .... After <14 Nf7 Rg8 15 Qxe6+> he ends up at least a whole piece up. In fact it looks even worse than that for black.> Yes, youre right

  kevin86: The point of this one is that a knight outposted on e5 is far stronger than the material sacrificed.
Apr-29-11  YouRang: Like a bunch of others, I saw 10.e6 right away with the idea of sacrificing the exchange (after 10...Bxe6) and putting my N strongly on e5 and then bringing my queen into the attack.

I had trouble seeing the continuation, but the first few moves seemed so strong that I was sure they were right.

When I checked the game, I was at first satisfied to see precisely the moves I expected, but then became somewhat chagrined when I realized that the solution went a *lot* deeper than my expectations.

  thegoodanarchist: After 22.Qf4+ both Black rooks hang and the mate threat is gone. Game over.
Apr-29-11  newton296: houdini finally cracks this postion at the amazingly deep, deep, depth of 26

here is the win for white

Analysis by Houdini 1.5a w32: d=26

1. (0.81): 1.e6 f6 2.Bf4 a5 3.c4 g6 4.cxd5 Qxd5 5.Qe2 Bg7 6.Rd1 Qf5 7.Bg3 which leads to this position

now the best play is:

1. (1.08): 7...g5 8.Nd2 0-0 9.Nc4 Ba6 10.Rd7 Rfe8 11.a4 Qg6 12.b3

leading to what I believe is the following won position.

white is leaning all over the board.

Apr-29-11  ZUGZWANG67: Ok. Last night I was a bit tired and could not find anything crushing after 10.e6 f6 11.Nh4 g6 (to prevent 12.Qh5+ g6 13.Nxg6) and mistakenly suggested 12.Nf5, 13.Qg4 and 14.Nxg6 as a possible continuation. Of course, that is illegal stuff. What I meant is 12.Qg4 (D), with the threat of 13.Nxg6.


click for larger view

And after 12...Rg8 13.Nf5 does W has more than a potential attack? Ok. Let's assume that this is the kind of «B is forced to concede a positionnal avantage to W to avoid losing immediatly» puzzle.

BTW, 11.Nh4 is ranked first best by RYBKA at +0.75 at 17 plys after 7 minutes. 2nd is 11.Qe2 at 0,69 and 3rd 11.Bf4 at 0.62. In my opinion 11.Nh4 is a more human move...

But RYBKA goes 11...g6 12.Qg4, which is what I suggested, but then diviates 12...Qb6 (logical) 13.a4 a5 14.Rb1 Rg8 15.Nf5 Ba6 16.Be3 Rh8 17.Nh4 after 19 plys, 10 minutes (+0.76) (By the time I finished writing this line the evaluation changed...)

Apr-29-11  David2009: Balashov vs R Sabjanov, 1994 White 10?

I can't find a good plan or move for White here. 10 e6 Bxe6 11 Rxe6 fxe6 12 Ne5 g6 gives White nothing. Alternatively 10 e6 Bxe6 11 Be3 seeing 11...Qb6 12 b4 but 11...Qd6 seems to hold the extra Pawn. OTB I would probably settle for 10 Be3 e6 11 Bg5 hoping for exchanges, but 12...Qb6 looks fine for Black. Time to check: ====
Missed it - unless this was a spoiler?

Crafty End Game Trainer link to the puzzle position as above: http://www.chessvideos.tv/endgame-t...

The EGT finds the Black defence I was afraid of viz. 10 e6 Bxe6 11 Rxe6 fxe6 12 Ne5 g6 and now 13 Qg4 is met by 13...Bg7 14 Qxe6 Bxe5 etc ( ).

Time to read the other kibitzes and see if there is a convincing White win.

POSTSCRIPT: Useful kibitzing, in particular the strategic assessments by <Life Master AJ> and <dzechiel>. On reflection 10 e6!? is the best practical chance in an otherwise bad position. <tacticalmonster> gives 10...Bxe6 11 Rxe6 fxe6 12 Ne5 g6 13 Qf3! (the resource I had missed) when the EGT defends with 13...Qc8 with an unclear position.

If anyone can beat the EGT from the diagram position, please post your winning line. You are White in the free internet link given above, drag and drop the move you want to make. For maximum satisfaction beat it without using silicon - Fritz 6 or 12 out-gun the EGT because they use greater depth of search, but the EGT is always resourceful and aggressive especially when the endgame proper nears.

Apr-29-11  ZUGZWANG67: <<David2009>: The EGT finds the Black defence I was afraid of viz. 10 e6 Bxe6 11 Rxe6 fxe6 12 Ne5 g6 and now 13 Qg4 is met by 13...Bg7 14 Qxe6 Bxe5 etc ( ).>

I would prefer 13.Qf3 as it forces something. And in fact RYBKA gives 13.Qf3 +1.83 at 18 ply after 3 minutes; but assesses 13.Qg4 at -0.61 at 18 ply. After 13.Qf3 Qd6 (13...Qa5?? 14.Qf7+ Kd8 15.Nc6+) 14.Qf7+ Kd8 15.Bf4 (threatening a discovered...) 15...Bh6 (forced?) 16.Bxh6 Qxe5 17.Bg7 (Oooops!)


click for larger view

17...Qe4 etc...By the time I finished writing this Rybka reevaluates 13.Qf3 at 1.76 at 20 ply and roughly 8 minutes; and 13.Qg4= -0.58.

A question arises after 13.Qf3 and it is this one: where play the BQ? At some point during it's analysis RYBKA bet on 13...Qb6 and 13...Qc7 but turned to 13...Qd6. One problem with the b8/h2 diagonal is the arrival of the WB at f4 (moreover 13...Qb8 has the additional drawback of Nxc6+ after the BK reaches d8). But why not 13...Qb6?

Here is what I found: 14.Qf7+ Kd6 15.Qxe6 threatens 16.Nf7+ and 16.Qd7 mate. So 15...Kc7 but 16.Qd7+ anyway; and 16...Kb8 17.Nxc6+ wins the BQ.

Finally, I believe, still, that B should answer 10...f6 after 10.e6. This has the virtue of avoiding several acid moves such as Ne5, Ng5 and removes the teeth from Qf3. Thus, the puzzle today has the point of forcing B into a positional disadvantage if he wishes to stay alive. That is, he must play 10...f6. But then the e6-pawn is strong.

Peace!

Apr-29-11  ZUGZWANG67: <<ZUGZWANG67>:......Here is what I found: 14.Qf7+ Kd6.....>

Rather 14...Kd8.

Apr-29-11  goodevans: <David2009: ... I can't find a good plan or move for White here. 10 e6 Bxe6 11 Rxe6 fxe6 12 Ne5 g6 gives White nothing.>

I do so enjoy pitting my wits against Crafty. This time, though, its chosen defence isn't too hard to crack:

<10 e6 Bxe6 11 Rxe6 fxe6 12 Ne5 g6> (... Qb8 is probably best) <13 Qf3 Qc8 14 Qf7+ Kd8 15 Bf4 g5 16 Bxg5>.

This much I'd worked out previously before you posted the Crafty link.

<16 ... Ra7 17 Bf4 Rb7 18 Nd3> threating Nc5.

At this point Crafty chooses to give up the B with <18 ... Bh6> which leaves white with a clear advantage. After that the win is just "a matter of technique" (which is code for the fact that I screwed up a dozen of so moves later! However, at the point where I blundered I still had a good advantage).

Apr-29-11  newton296: <If anyone can beat the EGT from the diagram position, please post your winning line.>

houdini mated EGT in 34 moves! lol! guess egt isn't as strong as you thought.

Apr-29-11  rilkefan: I seem to be making progress against the EGT with h4, but it keeps playing ...c4 and I can't resist opening up the qside and then can't keep both wings under control enough to win.
Apr-29-11  cyclon: Quite late now, but let's see. I'd suggest 10.e6. Other moves are rather developing moves. Aim of this move is to hinder Blacks development. If Black rejects the sacrifice by 10. -f6, then 11.Nh4 g6 (-h5 12.Qd3 and Blacks got simply too many holes in his boat) 12.Qg4 Rg8 (-f5 13.Nxf5/-Bg7 13.Nf5) 13.c4 and Blacks got some serious cramps. If he accepts by 10. -Bxe6, then 11.Rxe6 fxe6 12.Ne5 and if -Qd6/c7/b8, then 13.Bf4 with clear advantage, also 13.Qh5+ may be plausible. After (12.Ne5) -g6 13.Qf3 Qc8 14.Qf7+ Kd8 15.Be3 Black is almost completely locked. Whites plan may be Bxc5-c4-Rd1. If (12.Ne5) -Qc7, then 13.Qh5+ g6 14.Nxg6 hxg6 15.Qxh8 o-o-o 16.Qg8, Whites edge. If (10.e6) -fxe6, then 11.Ne5 g6 (threat was 12.Qh5+) 12.Be3 with clear bind though I did not find a short clear-cut win for White.
Apr-29-11  ZUGZWANG67: <<newton296> 1. e6 Bxe6 2. Rxe6 fxe6 3. Ne5 g6 4. Qf3 Qc8 5. Qf7+ Kd8 6. Bf4 g5>

Funnily RYBKA prefers 13...Qd6 (see my previous post).

The move 15...g5 is probably the best way to prevent something like Nd3 followed by Be5, I guess. From d3 the WN would eye c5, and from there e6.

But again I think 10...f6 is best for B.

Took me about 20 tries again, but eventually was able to keep EGT bottled up until I could force favorable trades, get the exchange back, and come out a couple of pawns ahead in a Bishop ending.

  patzer2: <Phony Benoni> Yes it was, I've already deleted it here.
Apr-29-11  stst: Tiresome vs Difficulty!
Apparently the two poles for Bk K are f7 and d7, both of which will be under attack if W N can go e5, this gives clue as first to advance P to e6: 10.e6 Bxe6 (if fxe6, the h5-e8 diagonal will be exposed) 11.Rxe6 (R sac) fxe6
12.Ne5 g6 (forbid Qh5+)
13.Qf3 Qd8 (allow escape sq for K)
14.Qf7+ Kd8
15.Bg5 Kc7 (escaping)
16.Bxe7 Kb8...

and it's still a long way to go

  Phony Benoni: When chessgames.com first started these puzzles, they often called them <tactical exercises>. I think that's a good description of what we've got today.

Generally, a puzzle has a more or less definite answer. It may be hidden and fiendishly difficult to find, but it's there.

Today, we are presented with a common tactical device: sacrificing a pawn and/or the exchange on e6. This doubles Black's e-pawns, establishes a strong outpost knight, and slows Black's kingside development. Most everybody has found the first three moves or so, but trying to decide if either side has sufficient compensation is like trying to decide if the Sicilian Defense is sound or not; there's just too many variations. Even our Dueling Engines are having problems making a definitive justment.

What we can do instead is consider ideas for both sides that arise in this type of position. In other words, <tactical exercise> that will benefit us when the opportunity arises.

Yes, this is an example of chess for dumbbells.

  Once: <Phony Benoni> Excellent summary!

I would only add one thought. I am not so sure that the term "tactical" quite does it for me. This puzzle seems to be bordering on the strategic where precise calculation is not as important as imprecise fuzzy judgment.

The patzer adds up the material values of pieces to decide whether a line is worth playing or not. By contrast a GM puts a "value" on things that cannot be measured - open lines against the enemy king, depriving him of the right to castle, an outpost for a knight, etc.

Perhaps that is why CG dropped the term "tactical exercise"? It's not just a case of "white to move and mate in 3", but "what would you play in this position?".

And that could be just as much a matter of intuition and judgement about a strategic position as it could be a matter of analysis and calculation about a tactical position.

Apr-30-11  cyclon: <Once:> A good comment.
