The Longest Win of the Week

It's time to get back into looking at some endgames, and the best way to start is to download The Week in Chess  (TWIC) and sort the games according to how many moves were played in descending order. The latest TWIC is number 1038 and Mark Crowther has been running the site for over 20 years now, an amazing achievement and a great service to chess.

Anyway, once downloaded I like to look through some of the longest games, and see if there are any endgames which interest me. In the latest edition, I saw a game between A. Bergougnoux(1895)-J. Hebert (IM 2378) which reached the following position:

Like most club players, I'm guessing my knowledge of rook endings is pretty patchy. This game ended in a win for black, and my first thought was why isn't this is a draw? So I went to Averbakh's "Comprehensive Rook Endings" and looked at the section on where a rook fights against rook and doubled pawns. Here's what the Russian Grand Master and endgame expert has to say about these types of positions:

"Compared with the other forms of pawn structure, doubled pawns are less dangerous. We will first consider examples where the defenders king stands in the way of the pawns. In this case the result is normally a draw"

Ok, that is pretty much the same for rook and pawn versus rook endings, and it describes the position above. Averbakh then goes on to say that a passive rook, or when the defending king isn't in front of the pawn can affect the result. The examples he uses are excellent!

In this position, the defender has to use the same procedure as if the d4 pawn wasn't there. That is, wait till the pawn reaches the 6th rank, and then move behind the enemy king to start checking. 1.Rb7 Rg6 [Cutting off the white king] 2.Rb6

 2..Rg4!! [This is important. Heading for the back rank now is premature: 2..Rg1 3.Kc6! when either check fails] 3.d6 [3.Kc6 Rxd4 doesn't help white 4.Rb8+ Ke7 is a theoretical draw as the defending rook is behind the pawn and the king isn't cut off] 3..Rg1! [Now the rook heads for the back rank when there is no useful shelter for white's king]

White can make no progress. 4.Kc6 Rc1+ forces the king to retreat, while 4.Kd5 doesn't require any special treatment, so black could play 4..Rh1 gaining checking distance and waiting for white's king to try to advance. Now, if you look at the position in the first diagram, you'll see a position not unlike this one, a cast iron draw!

Sometimes, the draw is not so easy:

Here, for example, white has advanced the pawn to the brink of promotion, and the threat is Re8+, so black must seek drastic measures. 1.Rh2+ Kg6, and now that the black king is stalemated, 2.Re2!! and black's rook will keep diving in front of its white counterpart!

If the defensive rook is passive, things aren't easy, and maybe even impossible.

Black's rook is passive and white's king has penetrated the 6th rank. 1.Rd6 [Taking control of the 6th rank] 1..Rf8!? [A last attempt]

2.g5! [2.g7? Rf6+!! another stalemate possibility] 2..Ra8 3.g7 Rb8

White has a very simple plan. Rf6-f8, leading to a won pawn ending. 4.Rf6 Ra8 5.Rf8+ Rxf8 6.gxf8=Q+ Kxf8 7.Kh7 and white will promote on 3 moves.

Finally, take a look at this amazing technique!

Black's king is cut off, but the win isn't as straightforward as you'd think. Without the b6 pawn, white would build a bridge on the 5th rank, but that is now not possible. 1.Rd2+ [Driving white's king further from the action] 1..Ke7

[2.Rd5 fails to work after 2..Ra1 3.Kc7 Rc1 and white's king must go back to b8!] 2.Rd6!! [An unbelievable technique!] 2..Rc3 [Taking the rook doesn't help 2..Kxd6 3.Kc8 Rc2 4.Kd8 Rh2 threatening mate, but white promotes with check! 5.b8=Q+]

So what now? 3.Rc6!! [Building a bridge! If the rook isn't taken, then white's king will escape to c7] 3..Rxc6 4.Ka7, and black has no checks and cannot stop promotion!

So that's the theory, what about the example we started with?

I guess we've all been in this sort of position where we're struggling to draw against a much higher rated opponent, who just keeps playing and playing. Hebert changes the structure to try to upset his opponent. 1..f2. White still manages to keep playing solid moves. 2.Ra7 Kg5 3.Rg7+ Kf4 [A repetition is a good sign for the defender] 4.Ra7 Kg4

[My first reaction when I saw this position was to play 5.Ra3 cutting off black's king. 5..f4 and now throw the rook up the board 6.Ra8 when I don't see how black will progress. White played differently, but still good enough to draw] 5.Ra8 [According to Nalimov Tablebase, this position is drawn] 5..f4 6.Ra7 [Again, I like 6.Ra3 cutting off the black king. If 6..f3, white has the stalemate try 7.Rxf3!] 6..Kg3

In this position, after an heroic defence, the game ended. I'm not sure if white ran out of time, but I hope white didn't resign. According to Tablebases there is a move to draw, but only one. 6..Ra3+! [6..Rg7+ 7.Kf3 is hopeless for white] 7.f3 [Retreating the king back to g4 is no winning attempt] 

7..Rxf3+ with the same stalemate  theme! 8.Kxf3 stalemate!

Recharging the Batteries

Holidays and travelling can be many things. One can go somewhere for relaxation, or for adventure, to party or pamper, to discover new experiences or revisit favourite places. There seems to be no end of reasons for going somewhere. However, on coming back home, we are all hoping to be invigorated from our holiday experience and ready to jump back into normal life with a refreshed outlook.

This last week I've spent time in the southern island of New Zealand. I've been there before, and visited places both new to me and where I'd travelled before. I went with my lovely wife Caroline, and our friends Nick and Zoe, spending a week in Queenstown, with an overnight excursion to Milford Sound. The point of the holiday for me was to relax, walk a bit, see some of the most beautiful landscape in the world (and cleanest air and water), and spend quality time with those people I most value.

It's less than 4 hours flight to New Zealand, and we stayed in a lakeside apartment. The view from our apartment was already refreshing.

 We arrived on Nick and Zoe's anniversary which was a nice touch. It meant heading to town and a meal on Saturday night. The biggest noticeable difference between Melbourne and Queenstown is the amount of people and traffic. Even Saturday night in Queenstown was a gentle experience with no trouble finding parking or a place to eat. A week without queues or traffic jams was indeed a refreshing experience.

Queenstown is an adventure playground for those who are that way inclined. You can ski, bungy, canyon jump, white water raft, climb, mountain bike, jet boat etc. I must admit that I'm not into that sort of thing, but it doesn't stop me taking in the views of those who do.

Queenstown was only a base for us, albeit a beautiful base. We hired a small car for the week which took us to some historic and scenic places. The area became populated in the mid to late 1800's due to the discovery of gold in the Otago region. Arrowtown is a living monument to this, with a Chinese Settlement area which preserves the buildings of the early Chinese miners.

Arrowtown was more than just history, nestled in magnificent scenery

There is no doubt that the area is amazingly beautiful. I'd be hard pushed to decide whether Queenstown or Wanaka were more stunning, not to mention Te Anau, or the areas between these places. The mountains, lakes, rivers and forests are beautiful. However, these are eclipsed by Fjordland, the scale of the beauty I'm unable to capture in pictures. You really do have to go there to experience just how amazingly beautiful this area is. I took my second trip to Milford Sound and was just as stunned as the first, perhaps even more so as the weather was completely different making the Fjord look totally different.

It was worth getting up at 5.45 am to get this view of Mitre Peak, Milford Sound

So am I recharged? Absolutely! It was just the break that I needed. A week of losing oneself in a pristine environment to come out the other end ready to take on the world. Highly recommended!
