|Mar-14-12|| ||Once: <VincentL: Given that this game was played between two grandmasters I am a bit surprised that black did not resign around move 24.>|
I suspect the fact that it was a team championship had something to do with it. You wouldn't want to be the first to cash in with an early loss.
Besides, I thought that black had real chances to draw this. Once the rooks were off the board all he needed to do was exchange his bishop for the white rook pawn and it's a draw. And that rook pawn had to cross a couple of black squares to get to a8.
White had to be patient to push his a pawn only when the bishop couldn't snaffle it.

I know from personal experience how painful it is to be the first loser in a team match. Then again, it can be even worse when the scores are lvel and you're the last loser. More than <once> it happened to me
|Mar-14-12|| ||FSR: Surely after 25.Qc2 intending 26.Rd1 White would have won a lot faster? It seems absurd that it took White, up a piece for a pawn, over 60 more moves to win.|
|Mar-14-12|| ||LoveThatJoker: <sevenseaman> Nice one! 1. Ne8+ Ke6 2. f5#|
Although it wasn't hard and I solved it quickly, you are correct in saying that the mate doesn't immediately spring to mind as it isn't a common pattern (like Q+N double check and smothered mate with N, for example).
Another lovely mate that has a similar position to yours is one by Topalov (if I recall correctly): the winning side has pawns on one side of the board and with a B and N they manage to create a most beautiful and unique mating net.
|Mar-14-12|| ||Phony Benoni: You can see the match details here (Olimpbase is wonderful!)|
This game was from round 3, and Miezis' win tied the match. So it's quite possible that match considerations led Navara to play on, not to mention that fact that a 2700-player can't enjoy losing in under 25 moves.
But I think the material configuration was his main motivation. As <Once> pointed out, drawing with ♗ vs. ♘♘ is conceivable. Had it been ♗♗ vs. ♘, I think he would have saved his time and energy.
|Mar-14-12|| ||Once: <scormus> That's an interesting point ... so we are saying the optimal time to lose in a team game is somewhere in the middle. You don't want to be the first as everyone will notice you, and you don't want to be the last as someone will say that your result lost the match.|
Hey, maybe that could be a new chess book .... "How to lose at chess"??? The techniques and strategies for losing with as much dignity as possible.
I think I've got all the experience I need to write that one ;-)
|Mar-14-12|| ||chrisowen: Swell it nice in dilemma again the demon Navara goeas astray it early on |

|Mar-14-12|| ||MichaelJHuman: I saw Nd7, but I missed that the bishop could take the pawn, sadly. So I think I fail.|
|Mar-14-12|| ||pericles of athens: <Memethecat> haha :) i'm a beginner, so it makes me really happy when i solve one quickly. |
also, endgame technique is something that's tough for me. so today was extra special :)
|Mar-14-12|| ||master of defence: Why 20...Rxe3?|
|Mar-14-12|| ||I play the Fred: <Why 20...Rxe3?>
Hopefully someone who's <good> at chess will answer this question too, but after 20...Rxe3 21 fxe3 there's a ton of weak dark squares around the white king.
|Mar-14-12|| ||offramp: Superb ending by Miezes; after ...Bxa7 black may have thought that all was drawn - not so!|
|Mar-14-12|| ||soberknight: I solved it. It's an unusual position but I knew immediately that axb8 could not be right.|
The tablebase has mate in 17 from the moment White takes the last Black pawn (cool knight-fork tactic, by the way).
|Mar-14-12|| ||Once: <master of defence: Why 20...Rxe3?>|
Fritz doesn't understand it either. He reckons that it increases white's advantage from just under a pawn (+0.91) to over two pawns (+2.46).
Black may have panicked slightly as there is no obvious way to stop white from playing Rxd3 to exchange rook for two knights. The black knight on d3 is really going to struggle retreating anywhere safe.
So he <might> have gambled that Rxe3 would give him something to play against - the newly weakened isolated e3 pawn. And later on we see black trying to harass this pawn with Re8 and Ba6. I don't think it is particularly convincing, but at least it is an aggressive plan for black.
I suppose the moral is that if you are losing you might as well go down spectacularly by trying to create a bit of counterplay.
|Mar-14-12|| ||LoveThatJoker: <master of defence> I agree with what <Once> has written regarding your excellent question.|
Keeping with this, it is safe to say that 18...Nbd3? was the mistake that essentially put Black in the hole for the rest of the game.
It's possible that Navara was thinking he had ...Nf4 at some point but missed White's lovely 19. Qc2!
As an improvement, without the aid of my trusted Stockfish, I recommend 18...Nc6 as good for Black. The idea being that 19. b4 and 19. Nb5 are both met by the strong 19...Ne4! when Black's queenside pawns are safe from capture and Black threatens to untangle with ...Qf6 (or possibly even ...Qe7) at some point with a fair game.
Also, if 19. Qc2 Qc8 (not 19...Qe7/19...Qf6 20. Nd5!) 20. Nb4 Ne5 when Black is defending, but defending well.
|Mar-14-12|| ||BOSTER: I guess that <FSR> is right saying <It seems absurd that it took white,up a piece for a pawn, over 60 moves to win>. |
This is the position with white to play move 35.

I guess on <CG> site everybody would play 35.Nxf7.
Here couple lines:
35.Nxf7 b5 36.Nxh6+ Kh7 37. Ng5+ Kxh6 38.Qh4#
or 35.Nxf7 Rxf7 36.e6 Rxf3+ 37.gxf3 Qe7
38.Qe4 and game is over.
|Mar-14-12|| ||JG27Pyth: @sevenseasman
I like that puzzle. I think it's like today's puzzle -- a perfect wednesday --
|Mar-14-12|| ||An Englishman: Good Evening:
Easy, but only because I composed a puzzle with a similar theme. Mate in 4.
White: Kb6, Bc7, Nd7, Ne7
Black: Ka8, Rc8
Main line: 1.Nd5,Rb8+; 2.Ka6,Rb1; 3.Nb6+ (either) and 4.Nxb6X. Not great, but a little amusing, as the key puts the Knight in position to attack two squares occupied by his comrades.
|Mar-14-12|| ||chessgames.com: <This is perhaps a little easy for Wednesday.> We know, but we deemed it a little too lovely for a Tuesday. In fact it's one of the prettiest puzzles we've had in a long time; relying only on real games, it's a rare treat when we can display something as pretty as a composition.|
|Mar-14-12|| ||stst: Simple enough, observing the B has only two options: (A)c7, (B)!c7 (programming language,) i.e. non/not c7.
IF (A), ... Bc7, 89.other Nxc7#
IF (B), ... B but not c7, 89.Nb6# (neither N would be bothered by the B=Bishop!)
|Mar-14-12|| ||sevenseaman: Good that two of us, <LTJ> & <JG27Pyth> tried and cared to write about it. I hope some others too have.|
Being a tad pedantic but the position can be slightly juggled for a similar solution.

w t p & w.
These puzzles are all about the human mode.
<BOSTER> A very interesting and engaging discussion! I like such ideas on a chess page.
<CG.COM> I completely endorse the view you have taken in deciding to present this composition-like puzzle on the POTD forum. Its exactly the puzzle I saw on a Tactics Computer.
When I first met this one there, a mere day before, I found it hard to believe it was from an actual game. I almost precipitated into daring them to prove.(They claim all their problems relate to played games). Very nice.
|Mar-14-12|| ||karnak64: I guess the thing I really admire is Miezes hanging in there this long to eek out the win. I don't thing I have the mental stamina to play something like this out. I'm rather impressed.|
|Mar-14-12|| ||avidfan: <An Englishman>: Good Evening: The final position in your composition has the Bishop controlling b8 instead of a white square in a normal ♗♘ mate.
