Using Deep Fritz 14 on a smartphone

4/13/2015 – Recently, Danny Gormally wrote an entertaining article ‘The Komodo files’ where the Grandmaster describes his experience of working with a chess engine. While it is certainly the Summa Cum Laude of chess engines, the weekend chess warriors may balk at carrying a laptop. In this article you will see how you can easily fulfill your needs with Deep Fritz on a smartphone.

Meanwhile, in an interview, Vishy Anand said that smartphones were now strong enough to beat the world champion. Here was a nice opportunity to test this assertion. How would ChessBase for Android smartphones, with Deep Fritz 14 built in, compare to GM Gormally’s analysis with Komodo, ‘rumoured to be one of the strongest engines around, if not the strongest’? For those interested in the technical details, I used my two-year old LG Nexus 5 Googlephone and generally followed Fritz’s instant recommendation. In some complex positions, I let the program run up to a depth of 20 ply (taking about a minute on the Googlephone).

In the Engine settings, you will find an assortment of engines. Don't
think of them as stronger or weaker, but rather as different styles, all
of which are World Champion caliber.

Once done, you will see the eninge you chose. Deep Fritz 14 on Android is true to its 'Deep'
roots, and can take full advantage of mult-core processors. Quad-core smartphones are
commonplace nowadays.

Daniel Gormally vs C. Huassernot

As can be seen, sometimes one engine can choose a top move, in minor
disagreement with another engine, but that fits your understanding and
perception of the game. It makes sense to play it than one you find bizarre.

Here is another short example: 

Daniel Gormally vs C. Haussernot

[Event "Hastings"] [Site "?"] [Date "2015.??.??"] [Round "?"] [White "Gormally, D."] [Black "Haussernot, C."] [Result "1-0"] [ECO "B51"] [Annotator "Danny Gormally"] [PlyCount "33"] [EventDate "2015.??.??"] [SourceDate "2015.03.01"] 1. e4 c5 2.

O-O a6 {This may be playable but would be uncomfortable to defend as a human. Nevertheless, having played Qa5+ Black must be prepared for a principled follow-up as the text just leaves White with a strong risk-free initiative.}) 8. d5 a6 9. Bxd7+ Bxd7 10. O-O Nxc3 11. bxc3 Qc7 ({A solid advantage in Fritz's opinion that analyzes} 11... Bb5 12. dxe6 O-O-O 13. Rxb5 $1 axb5 14. Bg5 {and White has a clear plus.}) 12. Ng5 exd5 13. Re1 {Completely winning according to Fritz.} 13... Be6 14. exd6 Qxd6 15. Rxb7 Be7 16. Nxe6 fxe6 17. Qg4 {...} 1-0

As can be seen, in all three examples the key ideas and variations were quickly found by the smartphone. All this at an incredibly modest price of 10 €! While ChessBase on the smartphone doesn’t have all the features of the PC version, it is great value for money and handy to use. It has certainly made my preparation literally lighter as nowadays I don’t bother taking a laptop to a tournament.

Even this handheld device will take down the greatest grandmasters

The key to using engines is to know when to trust their evaluation and when to let them run a little longer. For serious readers, I highly recommend Robin Smith’s book ‘Modern Chess Analysis’ for examples on how this is approached by correspondence chess players.

While looking at the games taking place in the 2015 US championship, the game Holt-Troff caught my eye straight from the opening. I remembered a couple of classics in this Gruenfeld variation such as Petrosian-Fischer 1971 where Petrosian ended Bobby’s 20 game winning streak, but I was unfamiliar with the sacrificial idea 8... Rd8 used by Troff.

Here is a short video tutorial on analyzing your games with an engine in ChessBase for Android

No problem, I fired up ChessBase on my smartphone. It is in situations like these that the app’s value comes to the fore as it combines a database and an engine into one handheld program. I could quickly familiarise myself with previous games and analyse some ideas with the engine. For example, I wasn’t sure why Black refrained from playing 11... Na6 until Fritz showed that White can then win a piece for some pawns. The next day, I was pleased to see that GM Josh Friedel gave the same variation.

By the way, it was clear while watching with the help of the engine in the Playchess app, that White was not following up the opening in the most precise way. Ah well, it just goes to show that chess is played by imperfect humans- if not, it would lose its charm.

One dark side of the smartphone’s power is the potential for cheating. At the professional level, I fully believe it is the responsibility of tournament organizers and FIDE to ensure that it does not happen. At the amateur level, yes it is possible, in the same way I can dope myself with illegal drugs to run a local marathon as there is no monitoring. But what is the point? For most of us, these are hobbies and cheating neither has a large financial incentive nor is it personally satisfying.

How way to compare Kasparov Barracuda with Deep Fritz chesd program.?
maxath maxath 11/16/2015 10:41
Using DroidFish, with my opening book Goi.bin and syzygy ending tables installed, I reached a depth of 28 ply in just in precisely 1:00 minutes. I have a Samsung Galaxy Grand Prime, 4 threads (= # of cores) and 1 GB hash table. I have tested this program against deep Fritz 14 with an intel I7-4771 CPU: DroidFish on my smartphone has won the Deep Fritz 14 engine at its maximum level.

To honour Kotov's classic books GM Nigalidze will publish a book entitled "cheat like a grandmaster".
