A sad tale last night…
4 intrepid Manly lads ventured out to St George to play the leading team in our grade.
We were heavily out-rated on every board but that’s no excuse. We lost 4- zip and I let an easy win slip by blundering a piece.

Mistakes on both sides but marvel at the stupidity of 35 d7?? In a crushing position. :wall: It was a total hallucination. Focused on Bishop taking line so much that when I thought it worked I moved and completely forgot Rook could also take.
Here's the game lightly annotated based on my thoughts during the game,
Sorry it’s a bit long…Maybe someone can put it into Fritz and leave it overnight (or maybe longer!!)

Here are the moves for your entertainment! Comments welcome!

I like 22, Nxf7 followed by 23. d6. Maybe it's losing but it is spectatular! :)

Cool - appreciate the work. But I hope that football team represented by your avatar lose more games than Chelsea do next season!
God bless and good night. Cheers and good luck!

Are you sure it is lost after 48...Rxg4? Start with 49.Ra6! and Black won't become so dominant so easily.

Are you sure it is lost after 48...Rxg4? Start with 49.Ra6! and Black won't become so dominant so easily.Yes, my 49th is one of many moves in the game that are not best.... By then I was short of time too BTW.

Adamski

Err, is that a yes that you think you are lost after Black's 48th or?No, I have chances of saving the game. Must study such end games. Thanks for your input.

On move 15 isn't f5 totally winning for white?

Probably. Played 15 Rd1 too quickly on general principles of R on same file as Q must be right.
What particularly interests me is that even after I blundered my Bishop on move 35 did I still have winning chances? Visions of a mating net for his King e.g....

I woke up this morning with the realisation that in the good old days when the laws of chess permitted me to write my move down before playing it, I would (probably) not have committed this howler. I used to follow GM Alexander Kotov's advice from Think Like A Grand Master and write my move down before doing a final "blunder check" before playing it. In this case I would surely have noticed the Rook, too, could capture my Bishop!

I once noted it elsewhere but I still believe that it was a retrograde step to change the laws to outlaw this (still much used) practice. I haven't got the time now to look it up but what is the penalty/ ies open to an Arbiter to impose if a player protests that his opponent is writing his/ her move down before playing it? In one of my NSWCA grade match games this year my opponent did it consistently and I briefly thought of complaining to an IA who was present (but playing) but let the thought go as I did not want to kick up a fuss about something relatively trivial, and I was in "personal" agreement with the practice anyway! (But I no longer use it because I know it is against the laws of the game.) I know this isn't the right place to discuss this but it's stream of consciousness stuff for me so I am briefly doing so. Maybe someone can link to the appropriate thread. I'm curious, has anyone ever lost a game at high level for consistently writing the move down before playing it? I assume many players have received time penalties for the practice.:hmm:

It was a drawn endgame until 54 Ra6?? after which it is just lost.

Instead white could just play 54 Ra2 and keep moving the rook on the second file. If black moves his rook from the 4-th file then check. There is nothing black can possibly do.

Another possible move is 54 Ra3 and if checked keep the white king on g1 and h1 (h2 square needs to be guarded). Again I do not see how black can progress.

Finally, Ra6 would be a good move if it was made on move 52 rather than 54.
There is a general rule that one should not push pawns on the side that he/she has smaller number of pawns. Even though in this case h3 was not so crucial, it created a hole on g3 and limited number of options for white. So after 52 h3 Rd4 if white plays 53 Ra6 black can reply with 53...Kh4. Now the only move white has is 54. Ra3... (If white plays 54 Rh6 then 54... Kg3 with an ustoppable mate.)

Thanks for your wise words, Vlad. Hope to see you on Monday night. By then I should have stopped having nightmares about this game.

A Manly club-mate and friend of mine put the position after 34..Nd8 into Fritz 11. It came up with the following (in places possible somewhat esoteric?) line with White eventually winning. Black sacrifices a piece to make his passed pawns stronger but it fails. Any comments?

35 Ng3 Kh7 36 Nh5 Nb7 37 Nxf7 a5 38 Rf1 N7xd6 39 Bxd6 Nxd6 40 Nxd6 Rf8 41 Re1 Ra7 42 Nf5 a4 43 Re6 Kh8 44 Rxh6+ Rh7 45 Rg6 a3 46 Nf6 a2 47 Rd1 Rxf6 48 Rxf6 Rd7 49 Re1 Rd8 50 Rc6 Ra8 51 Ra1 Ra4 52 h3 Kg8 53 Re6 b5 54 Re2 b4 55 Raxa2 Ra3 56 Rad2 Ra7 57 Rd5 bf8 58 Kg2 Ra8 59 Nd4 Bh6 60 Rb5 and White wins the last passed pawn and wins the game.

Generally one should be extremely wary when someone's "computer analysis" of a position consists of a single line that is well over 20 moves long with no side-branches. Often the computer will pick a move as apparently the least worst at a certain point and not realise the drawbacks of that move until later.

In the line you give, by 43...Kh8 black is clearly losing. My own copy of Fritz11 after looking at the position for a while is now strongly preferring 40...Re7 to 40...Rf8. That very likely loses as well but black seems to put up much more prolonged resistance without the attacking rook pair on the board.

Fritz revises its opinions of positions based on what it learns about them later, so often if it prefers a line and then that line spirals into disaster, you can go back and check what it now thinks is the best move in that position.

Thanks for that, KB. Wise words! And yes, ...Kh8 seems very dubious. I'll ask my mate how he came up with the line.

There's nothing dubious at all about 43...Kh8 (indeed it's probably the best move in the position by far); I am just picking that as a point at which it is clear (to me) that black is lost.

It looks to me like the long line provided could be either a shootout line (Fritz shootouts are rubbish as an analysis tool IMHO - avoid) or a case of entering what the computer believes to be the best move at each point.

Agreed. 2. I think it's the latter but I will confirm (and also advise a better way to use Fritz 11 for analysis of positions).

So is Fritz 11 good value for money? How long do you generally have to leave it thinking on a move to come up with what seems like the best move? Might put it on my Christmas present list...

Thanks for that, KB. Wise words! And yes, ...Kh8 seems very dubious. I'll ask my mate how he came up with the line.Yes, he has confirmed it was the latter method - new analysis after each move. And yeah KB you're right again. 40...Re7 rather than ... Rf8, although Black still will lose the game but will last a little bit longer.

I think he now has some better ideas on how to use Fritz 11 so thanks again KB for passing that advice on.

Some of this would make good material for "Use and abuse of computers in game analysis", a thread I intend to get around to starting sometime in the next decade.
