iChess v5.0 on Android – Its brand new and colorful!

Over the past several weeks, we have been partly busy with iChess release. We slowly rolled it out to few set of users, squashed a lot of bugs (and silly mistakes), but its finally here! The latest Android version is now available for all users!

What’s New?

Background
Sometimes when you start an App project, you develop it with the knowledge and tools you have during that time. Over a period of time, your knowledge improves and you realize that the way you developed something in the past, was probably not quite the best way to do it. It can be made better.
So thats what we did. We changed the guts of the Android version and built-it almost from scratch!
This was done to make it better and improve the stability and fix bugs which creep in some weird scenarios.
Colorful & Curvaceous…



..with new Wooden Board Theme

..and colors!

Brand new Store design and experience!
 
Search any puzzle or publisher. View our Top Puzzles or your purchases, all in one screen! Find puzzles that you want based on various categories!

..and puzzles from ‘New In Chess’ publisher!

Puzzles based on your playing strength or from games of top players like Carlsen, Nakamura, Giri, Kasparov etc.
..and…

  • A single place to view and download all your purchases
  • Choose a different ‘Side to play’, in case your PGN has puzzles where the 1st move is for the losing side.
  • Its not only the App design that has changed, the underlying stuff and architecture
  • Stability improvements and bug fixes and more!
These are significant changes and might cause some bug here and there. It will be great if you could just email me (Can do that via the App too. MenuAbout Feedback)

If you don’t like something, just email me! Looking forward to your feedback!

PS. Some of these changes will be rolling out to the iChess iOS version too

Chess – How to improve your Tactical defense?

Chess is 99% tactics. Many games are won when you spot a tactical shot or simply miss one from your opponent.
Hence, apart from sharpening your own tactical skills, it is also important to improve your defensive skills, so that you don’t easily fall prey to your opponent’s Tactical shots.

The key here is to be aware of THREATS in any given position. When you are aware of the Threats in the position, you would naturally take precaution to not leave a piece enprise or safe guard your King from the impending mate.

So, improving your ability to spot Threats in the position is a sure shot way to bump up your tactical defense.

Take a moment to study the following position (It is White to move and imagine YOU are playing Black). It is a very simple position, but ask yourself.
“What is White threatening?”
“Are any of my pieces undefended?”

Once you notice that your Rook on a6 has no support and it can be attacked by Qc8 (with check!), you would know what to do! So if instead of White, it was your turn (Black’s move), you would naturally safe guard the Rook or exchange off the enemy Queen.

Another simple example (White to move and you are Black).
“What is White threatening?”

Qf8+ immediately finishes the game. So if you were playing Black and it was your move instead, you would protect against the mate with say …Kg7

A more difficult puzzle with Black to move. Ask yourself the same question.
“What is Black threatening?”

Oh, thats infact simple. Black would play Bxg2 mate! You now know the Threat.

What if the position was actually like this with Black to move:

You can immediately spot the tactical motif for your opponent. Remember you are playing White and the idea is to ask “What is Black threatening?”
The threat is: Black will play Qxf4 sacrificing his queen to “deflect” the White queen away from the protection of the g2 pawn. Then after you reply with Qxf4, your opponent (Black) will play the deadly Bxg2 and hold his head high up while the onlookers admire his skill.
Instead, if it was your turn to move (White), you would see the “Threat” and protect yourself against the embarrassing mate!

Summary

  1. Always ask yourself, “What is my opponent threatening?” or “What will be my opponent’s next move”
  2. Watch your opponent’s last move (99% of the times, your opponent’s last move has all the “Threats”)
  3. Always look out for the “checks”, “captures” and “threats” in the position.
  4. After a good amount of practice/training, points 1, 2 and 3 above would actually be obsolete and you would no longer have to do that, since your brain and intuition will automatically make you aware of the impending Threats. You would naturally get a feel for the position. However, never let down your guard!
  5. Practice, Practice, Practice, no short cuts!

How to practice?

  1. Pick up your favorite puzzle book (even if you have already solved all the puzzles). Now solve the puzzles all over again from the losing side’s perspective, every time asking yourself the simple question, “What is my opponent threatening?” (you play as the losing side). However it is better if the winning side is actually on Top (for a change!)
  2. iChess for Android has a very interesting feature which can be very useful for defensive training. iChess can rotate the board, such that the losing side (remember YOU are playing the losing side for now), is at the bottom. For every puzzle you solve, ask yourself the above question and go ahead and make moves for the winning side. This kind of training is bound to help you improve your Tactical defenses and overall “Threat” perception. (To turn ON this option, open iChess > Menu > Settings > Board Rotation > Select “Winning side on top”. Now for every puzzle, iChess will show the winning side on top and you have to make moves for the other side as if you are guessing what moves your opponent is going to make)
May Caissa be with you!
PS. All the above images are from iChess, with the board rotation feature turned ON as mentioned above.

iChess FAQs

How does the Scoring work?


For each puzzle solved = 10 points
Failed =  minus 5 points
Hint = minus 5 points
Total score = Total Solved – Total Failed – Total Hints taken

What do the Bird view colors mean?

Green = Solved
Red = Failed
Amber = Puzzles that you find difficult.

I do not want the app to automatically load the next puzzle. I want to review the current puzzle after I solve it. How do I do that?

Its in the Settings! Open iChess Settings > deselect “Solve and Load Next“. Now iChess will stay on the same puzzle once you solve it so that you can analyze it further.

Why does the Hint button change color?

The Hint button changes color according to the side to move. This should make it is easier to recognize the side-to-move than reading the “White/Black to move” text on top of the board.

If I choose to “Remove Ads”, do I have to pay again for other devices or if I re-install or reset?

No! Once Paid, your purchase remains with you forever, just like the Paid app! So even if you buy a new device or reset the existing device or uninstall-reinstall iChess Free again, you should no longer see Ads.
(IMPORTANT: You should be using the same primary email account on your device with which you made the purchase, else it wont work.)

How to practice Chess Openings with iChess

iChess v3.1.3 was released today with several bug fixes and stability improvements.

As you know, iChess is great for solving the pre-shipped puzzles as well as any PGN-puzzle file that you may have.
One minor unplanned feature, which was released in v3.1.3 is the support for studying Chess openings.
You make moves for the winning side while iChess plays the other side.

Here is how you can do it:
1. Prepare a PGN file with your favorite opening lines. This will be your opening repertoire.
It is better to have each variation as a separate game in the PGN. For your preferred side, mark the game as won, in the PGN. Say you like to play the Kings Indian with Black. Then save the full or partial game and mark it as 0-1 (in the game header). 
(This is the most important step for any serious Chess player and once you have your repertoire PGN ready, it can be used for many other functions within Chessbase PC software.)


2. Open the puzzle file in iChess.
3. Now just like regular puzzles, iChess will ask you to make the best move. One additional feature is that, if the game result it 0-1 (Black wins), then iChess will automatically make the first move for White. You make the best move for Black.

Ofcourse, you can use a Hint and all other iChess goodies!

This can be a good opening workout and imprint your favorite variations in memory. (Note: Even the top players need to “memorize” their opening lines”)

This nice little feature can also be used for Solitaire or Guess the Move kind of Chess. Load a PGN with master games and try to guess the moves for the winning side!

Note: Currently, iChess does not give points for every move you make, but only for the complete game.

Update to “Magic of Tal” pgn puzzle set

I have updated the “Magic of Tal” pgn puzzle set with the following changes:

  • Removed some puzzles which did not make much sense
  • Added some puzzles
After the cleanup, the puzzle set now has 275 puzzles in all (down from 300).
If you have already purchased, you should see a “Download” button when you click “Get more puzzles”.
