Chess Puzzles: World Champions 4+

I purchased this app for .99 and I can honestly say that it doesn't get better than this. The chess computer sometimes moves different than the original game, which is great--sometimes I can solve one, redo it, and take a while to figure out based on the other move it made. Chess books as great, but this tops them all and it's dirt cheap. Another plus, for me, is the custom skin options. I love the Leipzig pieces on gray background. It's so awesome and I wish my other chess apps had those pieces. The next best app is tchess. I was hesitant, but the computer and analyser are AMAZINGLY helpful. Spread the word for these great chess apps!

This app collects over 600 mating nets from real games, from two-movers up to over 15 moves. (Top-flight players resign when the net becomes obvious, but this app gives you the chance to administer the satisfying coups de grace, if you can find them.) would that we could find these positions over the board!

The app has some rough patches that can be fixed. On my year-old iPad Air, it still crashes if I tap "Previous game" even when there is one to select. There are undocumented functions, such as the mysterious "Figurine notion" I'm still trying to observe. Landscape mode, which it lacks, would be nice. A little editing of player names would improve things; I suspect some of the players with different names are really the same ones.

(A previous review commented on the delay when you make a "wrong" move, but I can explain that one: there is an evaluation engine that kicks in and generates a response if you don't make the right move.)

It would be nice to be able to search for mates by your favorite players. (Mine is Lasker.)

All in all this is a very nice collection and a fun app for any chess player to have!

This is a great collection of exercises on the tactical side of chess. They are organized staring with mate in two, then three, four, and so on. You can skip around as you like and I'm currently at the mate is five section. There's still one mate in four that stumps me though. I love that the computer will play any variation, so you can learn why "your" idea doesn't work. Puzzle hero, another great collection, doesn't do this. I recommend both. Thanks for this great piece of solid work!
