A random act of kindness

asimpereira vs NightFury
This was a position from my 5min blitz game on FICS today. I have 3 pawns for a piece. My opponent just played …Re8 to support the e7 pawn.

In this position, I played Bb6 since the Queen has no place to move. But my opponent replied with Rc6???

What would you do in this position?

.
.
.
It was obvious that he had a “Freudian slip” (or a mouse slip!) and ofcourse wanted to move his Rook to c7 instead of c6. So I captured his Queen and immediately offered him a draw! He accepted the draw.

Then I asked him on chat if he accidentally moved the Rook to the wrong square which he confirmed. He thanked me for offering a draw.

Feels good! 🙂 Happy Christmas!

Can you find the best move for Black? (Warning: bloodshed ahead!)

My 3 min Blitz game on FICS. Can you find what I played in this position as Black? (full game replay at the bottom)

How should one think in this position?
In a blitz game, there is not much liberty to “think”. But this is where Chess Intuition plays a big role.

1. White has just moved his Rook to e1 (away from his King and the important f-file)

2. Black has a nice pressure against the g2 pawn.
These two points should ring a bell that a Tactical shot is lurking and one should FIRST start calculating …Bxg2 (even before thinking of …Rxg2 since its easier to sacrifice a piece of lesser value)

3. After …Bxg2 Bxg2, the natural Qe4 pinning the piece should be considered. This brings Black’s most important piece in the game and closer to the enemy.

4. Analyze White’s most obvious response i.e. f3 which protects the g2 Bishop and attacks the Black Queen which is on e4.

5. This is a somewhat critical position and you should spend some time here. Consider the “shocking” …Rxg2 which takes away the last defender of the King and since you have another check with Rdg8.
The first obvious reply you should calculate is Kxg2 (Rook). When one has plenty of time on the clock, other King replies like Kh1/f1 can be considered (but why worry, since you have already recovered the piece if the White King does not capture your Rook!).

6. But what happens after Rxg2 and Kxg2 and Rdg8+? What now if the King moves to f2 i.e. Kf2? At this point, one should be happy to spot the nice little …Bh4 which brings the last Black piece into attack and takes away important dark squares from the White King.

7. I did not calculate any other move beyond …Bh4 except a quick little Rg2+ in case the King moves to d2. But this kind of think comes automatically to a “trained chess eye”. It should be comforting enough to know that the White King is all alone (except the passive e3 Bishop which is actually and unfortunately blocking his own Queen from protecting the King-side), whereas Black now has his Queen, Rook and Bishop. Apart from the King moving to f2, you would know that any other King move like Kh1 or Kf1 (moving to a White square) is bad since the Black Queen captures on f3 with a check.

World Championship App, Carlsen and some pics

“The first of its kind!”
This World championship match touched many lives, and mine has been no different.

Back in September, I approached the AICF with a proposal to develop a Android app for the Match. They liked the idea and the rest is history!


There were lots of new things that I had never done before with my other Chess apps. It was a big challenge. 


♚ The first line of code!

On, September 1st, 2013, I wrote the first line of code!
Given my familiarity with Java and affinity towards Google, I chose the Google App Engine as my server. (One of the main reason to use a separate server for my app was to reduce the load on the official servers, especially after the London Candidates’ debacle during the earlier rounds). There were many technical hurdles that had to be crossed.
Line by line, file by file, the Android app and the corresponding server was brought to life.
But the main setback was not a technical problem, but a lack of response from the concerned teams that almost threatened to derail the app or some of its features. 
There were so many questions that needed answers, but there was no one to answer!

♚ First board prototype

The first board prototype, using the color scheme matching the actual board from the Candidates! Lol. The teak theme was too dark on some phones, especially the black pieces on dark square.


♚ What you “fore-see” is not what you get!

But as it happens with so many projects, the end-product is almost always completely different from the initial idea that you had envisaged, and some times its good.
At some point, the “Cool Anand” and “Hot Carlsen” board ideas struck my mind.
The app had to be made personal. After all it was all about the duo. And the fans. Let chess fans proudly choose the board theme matching the player they support, is what I thought!


Tactics were never part of the initial idea, but they became one of the most liked features of the app! (Full set of 300 tactical puzzles of Anand and Carlsen are available for purchase via my iChess Android and iOS app)

Live video was! But even after the app was officially released, there were no details on how to access the live video! (lol, can only laugh when I think about it now!)
Picture gallery was optional, and remains optional till date! 😉
There were so many features that I wanted to add and so many changes that were requested by Chess fans, but then there is a limit to time, energy and motivation!

♚ Who will annotate the previous encounters?

The previous encounters had to be annotated. With my limited time and Chess skills, I could never had done justice to the master pieces. I initially approached a couple of Indian GM’s, one of whom is well known for his satirical posts. But I did not have the money to offer nor did they have the time. (Note, the app was developed for FREE with no monetary payment. Just for honor and pride, or “loyalty huh?” as Vishy Anand told me at the pre-match dinner party!)
Then entered, Sagar Shah, the most energetic and entertaining Chess annotator I have ever seen. His annotations are like poetry! He agreed to annotate for the share of the “glory” and no money, although I did tell him that in case there is a chance to monetize the app, then I shall pay him 30% of the revenue. Thanks to the server costs, the revenue is negative! Ofcourse, being the “official” app, it could not serve any Ads and generate revenue. Imagine the app saying, “you can only watch the first two games for free. Rest of the games need $0.99, each) 😛

♚ The first version

After several internal Beta test versions from Oct 21st to Oct 25th, the first version was released for public download on Oct 26th. I could now breathe easy, atleast that is what I thought!
Then followed a series of changes, bug fixes, improvements, additions, deletions. Overall, 15 versions were released since then, each carrying some improvement or bug fix or some unavoidable design change!

♚ Stats & Dates

  • Development started – Sep 1st
  • First version released – Oct 26th
  • Total active users – >45,000 (as of Nov 27) (my expectation before the match was a modest 5000!)
  • Average rating – 4.72/5 (389 of 471 were 5 stars!)
  • Top 3 countries – India (37.8%), Spain (7.72%), Germany (7.52%). Norway was #5 with 3.87% sessions.


♚ Thanks

This app would not have been possible without the kind support of so many Chess enthusiasts and even non-enthusiasts (the app icon was developed by a “non-Chess” guy!)
Starting with Bharat Singh, who liked the app idea and immediately called up to take this forward. Sagar Shah and Swayams Mishra who helped with the Previous encounters and Tactics respectively. Such was Sagar’s enthusiasm and commitment, that he would burn the midnight oil and stay up late till the morning and annotate the game (before he got busy with his own tournament)! I think it took a toll on him and he had a disastrous performance at the recently concluded Chennai Grand Master open tournament.
Soni Prasad, my college mate who designed the app icon even though he was faced with some personal tragedy and difficult situations.
Aart Bik, who offered the first “foreign” hand and translated the app to Dutch. BTW, he is the developer of the popular “Chess for Android” app.
Many of them came ahead on their own accord and helped with the translation. This is the real Chess spirit! Bruno Pellanda, David Kaufmann, Houssem Collo, Jan Hotarek, Michael Meyer, Sverre Eugen. And the many people on G+, Twitter and FB who helped with their kind and encouraging words.
Some times users don’t realize how their words (reviews in this case) can positively or negatively affect others. For instance, a user did not like the recently added Norwegian translation and chose to give a bad review. That was enough to upset Sverre, who had spent the time and effort to help translate and had personally offered his help in the first place. “So let them do it from here. I stick to only playing chess”, Sverre argued. The user who chose to award a bad review, never offered any help to correct the translation, inspite of asking for his feedback! Thats life!

♚ Future of the app?

Dalila – “I’ll miss seeing the coloured notification ‘a move has been made’“. It was indeed a part of my life for the past 3 months and for many fans world wide. This is quite evident from the amazing response the app received. And I am truly grateful.


At one point, the app was #6 in the Top New Free Apps in the Brain & Puzzle Category on the Google Play Store!
So whats next? Like Deep Blue, the super computer, the app will be disassembled! But the parts will be used for a future project with the intention of watching live games and even more! Stay tuned!

♚ Perks of the job

Watching the Opening ceremony from the front row!


Sitting on that chair, touching those pieces!



Oh and, congratulations to MAGNUS CARLSEN, the new World Chess Champion!
(My 10 year old niece, who was “not interested” in Chess, now likes Magnus Carlsen and has taken to chess again! She plays Chess with her 8 year old brother who coincidentally likes Anand…still!)

TIPS N TRICKS

  • Live Board – Swipe down to flip the board


  • Tactics – Swipe right-to-left to load next puzzle


  • Tweets – Pull down to refresh tweets


FAQs

“Google Play Services not available.” What does this mean?

To save device battery and data charges, the app uses Google Cloud Messaging (GCM) to send moves and other details from the server down to the devices. If the correct version of Google Play Services is not available on your device, then cloud messaging will not work. Instead, the device will resort to pulling moves from the server. This has the following implications:
  • Server will not be able to push any move notification to the device. This in turn means that the device will periodically try and fetch this information, resulting in higher Battery and data charges
  • No move notifications from the server. Hence moves may be delayed
  • Game start/end notification will not work 
  • Home/Lock screen widget will NOT automatically show the latest board position.


With “Google Play Services” error, will I be able to watch live games? 

Yes! However, there will be no moves pushed by the server to your device automatically, nor will there be any game start/end notifications. As long as you are on the “Live Board” screen, the app will show the latest board position and refresh at a 2 minute interval.


How do I add the Board widget to my Home screen?

Click ‘Widgets’ category on your Android device and scroll right till you locate the ‘World Championship Match 2013’ widget shown below:

Then drag it and place it some where on your home screen. The widget will automatically update and show you the latest game position, when the game is in play*.





How do I add the Board widget to my Lock screen?

Lock your device and swipe the lock screen widget till you see the below:
Touch the ‘+’ area and scroll to locate the World Championship match widget.

Then touch to select the widget and it will be added to the Lock screen.

Now when the game starts, you only have to look at your lock screen to see the current game position!*
Adding widgets to lock screen is available only on Android 4.2 and higher

CREDITS


* – Notification feature is not available on devices like the Amazon Kindle Fire etc which do not have the Google Play Services.
Please see ‘Google Play Services not available’ FAQ above for other restrictions for devices that do not support Google Play Services.
Lock screen widgets are only available on devices running Android 4.2 and above. 

** – If you would like to help and translate the App to your international language, please mail me at pereiraasim@gmail.com. Only the App could be translated. The vast amount of Game annotations and commentary will still be in English.

♚ IMPORTANT: The app supports nearly 4200 different Android devices! So there is a possibility that the app may not always look “pretty” on your device. If you are one of those, please drop me a mail at pereiraasim@gmail.com and I shall try to fix it. A bad review will not automatically fix the issue since most likely I would need more details from you!

Minor update to Analyze This app – Stockfish 4.0 & less battery drain and heating!

I have just released v2.0.6 of Analyze This app, with some important improvements:

  • Stockfish 4.0 – The Stockfish engine has been upgraded to v 4.0! I have found this version to be definitely better. This is also good on your battery, since by default it uses only a single core.
  • Less battery drain and heating – Using iChess on a multi-core device would often cause the device to heat up when continuously solving puzzles. This update brings better battery usage and definitely lesser heating!
  • Bug/Crash fixes – Some important bugs and crashes have been fixed.

This is just a small release. More “feature” updates are in the pipleline!

iChess v3.5 released – New dimension to solving chess puzzles

I am absolutely thrilled to release a new version of iChess with lots of interesting features and changes. This is iChess’ 21st release in 2 years!


NEW IN v3.5

  • iChess automatically tracks the puzzles you find difficult. Then you can go to the Bird view of that puzzle set and choose “SOLVE FAILED PUZZZLES” option to start solving them. This will start loading all the amber and red colored puzzles in sequential order so you can keep your bird view clean. Go green!
  • Now you can choose to rotate the board so that you can practice solving puzzles for the other side. By default, iChess always places the board so that the winning side is at the bottom. But solving puzzles with the winning side on top can give a new dimension to your Chess and improve your defensive ability as well as ability to spot tactics for your opponents! See Settings
  • Lots of UI improvements
    • Added Sound
    • New Open PGN screen to quickly load your pgn file without having to wait to auto-scan
    • Hint button changes color per the side to move so its easy for you to know which side wins in that puzzle
    • Dark Theme to cool your eyes if you don’t like staring at a completely white screen
    • Cool blue color
    • Prices in the puzzle store are in local currency plus other minor changes.
  • Remove Ads right from within the Free version. Now you don’t have to worry about losing your PGN files or score. See Settings to remove all Ads from the Free version and make it identical to the Paid.
  • Lots of bug fixes and battery improvements.
  • Support different languages. Some of the language translations may be incomplete. More coming soon.

Special thanks to Dejan, Dorian, Felipe, Fermin, Gergely, Michael, Raymond, Rudy and others who helped with the app.
