The First App

According to Wikipedia an app is a software that causes the computer to perform useful tasks. It is also a software which runs on smartphones or other mobile devises.
The beauty of the new mobile world is that it gives you a chance to make better use of your free time. Whenever you travel for work or for pleasure you are spending time in various vehicles, precious time that you are mostly wasting.
It is no longer like that thanks to the new app culture. One can use his/her time more productively by learning new things.
A chess app is an idea too.
My first app pays a tribute to one of the most ingenious players ever- Paul Morphy. The way that he attacked his opponents revolutionized the game and brought it to the next level.
What was his secret?
You will find the answers in the app, and here is a bit of it:

A Different Look at the Match Battle

I never knew that it was that difficult to win a match for the World Championship. Watch the exciting battle of Garry Kasparov and Nigel Short revealed.
At least, according to BBC ;)

4NCL


The White Rose of York is the symbol of the House of York and has since been adopted as a symbol of Yorkshire as a whole. During the civil wars of the fifteenth century, the White Rose was the symbol of Yorkist forces opposed to the rival House of Lancaster. This period of the English history is known as the Wars of the Roses. Ever since, the lovely flower became a symbol of the whole Yorkshire to the present. The main city of the Yorkshire area is Leeds.
What does this have to do with chess? Nothing, except for the fact that one of English teams is named White Rose. The people in charge were kind enough to invite me to take part in their wonderful 4NCL.
The British system of play is very interesting. Sixteen teams are divided in two pools of eight each. They compete in all-play round robin tournament where the four winners get a chance to qualify to the top eight and the bottom four will have to show their best in the lower pool to stay in the League. The direct encounters of between the teams in the groups count in the final eight matches.



Each team consists of eight players which have at least one woman in the squad, just like in France.
An interesting point is the eighty-point rule which means that a player who is rated 80 points below a teammate cannot play in front of him/her in the matches. On the other hand, a team which is homogeneous enough provides plenty of unpleasant surprises for their counter parts and tough moments of preparation.
Another interesting point is the wild card rule. This allows any team to add a new team member at any moment during the season. The new player does not have to subscribe in advance, he/she just appear for the weekend games to make things interesting. Saying that, it is not unusual to see at the last and decisive round a player like Ivanchuk popping up out of the blue or Judith Polgar at the female board. True, this usually happens to one of the two best teams. In this year those seem to be Guildford 1 and Wood Green.
One squad can have more than one team in the league and this allows some additional strategies. Guildford was not shy to bring a strong second team in their encounter against Wood Green. The attempt to steal points from the main rival though was unsuccessful and Guilford lost 2.5-5.5.
The weekend games on 15-16 February gathered together the cream of the British chess. Those were accompanied by almost all the best Scottish players and many more players from abroad. The lovely Hinckley Island hotel hosted the event and provided excellent conditions to all.
The White Roses managed to win both the matches and got a nice chance to qualify for the final eight upper division.

Dynamic and Positional Pawn Sacrifice

The seminar Chess 431 – Dynamic and Positional Pawn Sacrifice was concluded this Sunday on one of the best chess sites.
Among the examples that were covered was the following masterpiece by Veselin Topalov:
Topalov,Veselin (2812) - Wang Yue (2738)
Sofia MTel Masters 5th Sofia (4), 16.05.2009
[Rogozenco. D, Topalov V.]


1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 6.Ne5 Nbd7 7.Nxc4 Nb6 8.Ne5 a5 9.f3 Nfd7 10.e4 Nxe5 11.dxe5 [11.exf5 offers prospects of a slight advantage (Huebner,R): 11...Nec4 (11...Ned7) 12.Qb3 Nd6 13.Bd3 g6 14.g4 Bg7 15.Be3 Nd7 16.0–0–0 Qb6 17.Qxb6 Nxb6= Ѕ-Ѕ Carlsen,M (2770)-Wang Yue (2738)/Leon 2009 (47)]

11...Qxd1+ 12.Kxd1 Be6 13.Kc2 f6 [13...Bc4 14.Bxc4 (14.Be3 Bxf1 15.Rhxf1 is slightly better for White.) 14...Nxc4 15.e6 fxe6 16.b3 Nd6 17.e5 Nf7 18.Re1 gave good compensation to White in Berczes,D (2232)-Carlsen,M (2250)/Heraklio 2002]

14.Rb1



14...Nd7 An over-the-board novelty according to Topalov. Previously: [14...fxe5 was played, for example- 15.b4 Nc4 16.bxa5 (16.Bxc4 Bxc4 17.bxa5 0–0–0 18.Rd1 Rxd1 19.Nxd1 e6 20.Ne3 Ba6 21.Ng4 Bd6 22.Bb2 Rd8 23.Rd1 h5 24.Nxe5 Bxe5 25.Bxe5 Rxd1 26.Kxd1 g6= Ѕ-Ѕ Vallejo Pons,F (2629)-Kasparov,G (2847)/Linares 2003 (41)) 16...Nxa5 17.Be3 Bc4 18.Bb6 Bxf1 19.Rhxf1 Nc4 20.Kd3 and White was slightly better in Berkes,F (2614)-Kiss,P (2394)/Hungary 2005]

15.b4! [15.exf6?! exf6 would be better for Black only.]

15...Nxe5 [15...axb4 16.Rxb4 0–0–0 17.Be3 Nxe5 18.a5 would give strong initiative to White.]

16.bxa5 Bc8 [16...0–0–0? 17.a6+–]

17.a6!



The positional sacrifice disconnects the black pawns and creates plenty of weaknesses in the opponent's camp which can be used by the White pieces.]

[17.Bd2 Rxa5 18.Nd5 Rc5+ (18...Rxa4 19.Nb6) 19.Nc3]

17...bxa6 18.a5 [Black's queenside is very weak, he has problems completing his development and finding any activity. Therefore White's compensation for the pawn is more than enough and secures him better prospects.]

18...Nd7 [18...Be6 19.Rb6 Bc4 20.Bf4 Bxf1 21.Rxf1 Nc4 22.Rxc6 Nxa5 23.Rc7



23...e5 24.Bd2±]

19.Na4 e5 [19...Rb8 20.Rxb8 Nxb8 21.Nb6 Bb7 22.Bc4 e5 23.Be3±]

20.Bc4 [20.Be3!?]

20...Bc5 [White's compensation is more than obvious in case of-20...Bd6 21.Be3 Ke7 22.Rhd1]

21.Rd1 [A good alternative was 21.Nxc5 Nxc5 22.Rb6]

21...Bd4 22.Ba3 c5 23.Rb3 h5



[23...Ke7 24.Rxd4! exd4 25.Nxc5 Nxc5 26.Bxc5+]

24.Rdb1 Ke7?! 25.Bd5 [25.Nc3]

25...Ra7 26.Rb6! Topalov could not stand the temptation to sacrifice further the exchange!



26...Rc7? [The decisive mistake.]

[Necessary was 26...Nxb6 27.axb6 Rd7 and White has nothing forced. After 28.Bxc5+ (28.b7 Bxb7 29.Bxb7 Rb8 30.Nxc5 Rc7!; 28.Nxc5 Rxd5! 29.exd5 Bxc5 30.Bxc5+ Kf7! Topalov) 28...Bxc5 29.Nxc5 Rxd5! 30.exd5 Bf5+ 31.Ne4 Rb8 Black retains good chances of escaping with a draw. (31...Bxe4+ 32.fxe4 Rb8! (32...Kd6 33.Kb3+–) 33.Kd3 Kd6 34.Kc4 h4 is better for White, but there is no obvious win for him (Topalov).) ]

27.Re6+ Kd8 28.Nb6+– Nxb6 [28...Ra7 29.Kd3!? (29.Rd6 Topalov) 29...Bb7 30.Kc4+–]

29.axb6 Rb7


30.Rd6+! Ke7 31.Rc6 Rd7 32.Re6+ Kf7 33.b7

1–0
