Ugandan Chess Master


Every once in a while I have taken a break from posting on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) to mention happenings in Uganda, where Kennedy Kid Jon spent last summer (see "And Now For Something Completely Different..." and "A Short Break from the Jerome Gambit").

Jon's Uganda blog is at
http://www.jbkuganda.blogspot.com/

Word from the Uganda Chess Federation is that Moses Kawuma, a member of the Ugandan Olympiad Chess Team, recently scored 8-0-2 at the 2008 World Olympiad in Dresden, Germany. According to The Chess Drum, this performance (9/10) was enough for Kawuma to be granted the FIDE Master title.

Here are Master Moses Kawuma's games:

Jerome Gambit: Drilling Down (30)

In the last game in this "human vs computers" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) match, Yace Paderborn seems headed for the draw that Crafty 19.19 and Hiarcs 8 had found before it, when RevvedUp decides to vary – after all, his position is better.


Unfortunately, that gives the silicon beast the opportunity to lengthen the game and eventually outplay its human opponent.

Yace Paderborn - RevvedUp

7.f4 d6 8.fxe5 dxe5 9.Qh3+

Kd6 10.Qd3+

10...Ke7 11.Qg3 Kf7


The draw comes with 11...Kd6, when Yace Paderborn likely would repeat with 12.Qd3+, etc. Perhaps RevvedUp was aware of a couple of previous examples of this line of play – where Black won.
12.Qxe5 Bd4

15.Qg5 Rg8

"Objectively" stronger (i.e. a computer thought of it) was 15...Re8 16.Qxg7+ Kd6, but it is not hard to see why RevvedUp preferred the text, even at the cost of an even game.


16.e5 h6 17.Qf4 Re8 18.exf6+ Kf7+
Black's development and relative King safety easily compensates for the lost pawn. But, give White a few more moves to get his position together, and...

19.Kd1 Bxf6 20.Nc3 Kg8


Black has castled-by-hand and retains an edge.

21.Ne4 Rf8

Again, the dynamic aspects of Black's position compensate for the pawn down. Yace Paderborn, however, nibbles away, move-by move.

35.Be3 dxc4


This gives Yace Paderborn a passer, and may not be best.

36.bxc4 Ke6 37.Rb3 Bd4

This exchange opens the floodgates, and White's game improves rapidly. Perhaps something neutral like 37...Bg7 was better.

38.Bxd4 Rxd4 39.Rb6+ Kf5 40.Rxb7 Rd6 41.Rf7+ Kg4 42.Kc3 Kh3 43.f5 gxf5 44.Rxf5 Rh6 45.Rf2 h4 46.d4 Kg4 47.c5 h3 48.d5

Jerome Gambit: Drilling Down (29)



RevvedUp is happy to use the opening innovation in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) introduced by Shredder 8 in the last game (see "Jerome Gambit: Drilling down (28)") but his hopes for an early draw are dashed, nonetheless.




RevvedUp - Yace Paderbornblitz 2 12, 2006

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


7.f4 d6 8.fxe5 dxe5 9.Qe2

9...Nf6 10.Qc4+ Kd6 11.Qd3+

This Queen check, in a position where Black's Knight was not yet developed, led to quick draws in Crafty 19.19 - RevvedUp and Hiarcs 8 - RevvedUp. Unfortunately for White, here the Knight makes a difference.

11...Kc6
Black can go this way, instead of to e2 – but even in that case, White's thematic Qg3 doesn't force a repetition of position: 11...Ke2 12.Qg3 Nxe4 13.Qxe5+ Kf7 14.Rf1+ Bf2+ 15.Rxf2+ 16.Nxf2 and after White captures the Knight at f2 he will be down only the exchange for a pawn, but Black's game will still be much better.

12.Qf3

Fritz 8 prefers the exchange of Queens, but a pawn-for-a-piece is not the ideal Jerome Gambit endgame.

12...Bg4 13.Qb3 Qd4 14.Rf1

A slip, but 14.Qe3 Nxe4 was hardly attractive.

14...Qxe4+ White resigns

And Yet Wilder Still...


From Edward Winter's A Chess Omnibus (2003):



Back-rank mate


A bizarre game:


1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.Bxf7+ Kxf7 6.Ne5+ Ke6 7.Qxg4+ Kxe5 8.d4+ Kxd4 9.b4 Bxb4+ 10.c3+ Bxc3+ 11.Nxc3 Kxc3 12.Bb2+ Kxb2 13.Qe2+ Kxa1 14.Kf2 mate.


Seven [sic] consecutive captures by the black king and the option of giving mate by castling at move 14. Indeed, page 120 of Robert Timmer's Startling Castling! stated that White played 14.0-0 mate. That source gives White's name as F.C. Spencer, with no other details. When the game appeared on page 158 of the May 1894 Deutsche Schachzeitung White was identified as J. Spenser of Minnesota. Giving the score (also with 14.Kf2) on page 200 of its July 1917 issue, the BCM offered no players' names or occasion, but the score was said to be derived from the Illustrated Sporting and Dramatic News of 1894. It appeared in the 1895 book of Chess Sparks by J.H. Ellis, headed only 'Played at Mineapolis [sic] Chess Club about 1894'

Wildest!


Here's a Wild Muzio, presented in Edward Winter's 1996 Chess Explorations (source British Chess Magazine, September 1903, page 392):

Blackburne, J.H. - Amateur
simultaneous exhibition
Canterbury, 1903
(notes by Blackburne)

1.e4 e5 2.f4 exf4

On this occasion, to follow the fashion, I offered the King's Gambit wherever I had the chance; and to my utter astonishment, nearly allwere accepted. 'That's the way to learn chess', said I.

3.Nf3 g5 4.Bc4 g4 5.Bxf7+

An almost obsolete variation. Some 40 years ago or more, I frequently played it, but came to the conclusion that it did not lead to such a lasting attack as the ordinary Muzio.

When I sacrificed the bishop, one of the lookers-on asked what Gambit I called that, pointing to the next board. 'That', I said, 'is the Bishop's Gambit, and this is the Archbishop's'. The Archbishop was present at the time.

5...Kxf7 6.Ne5+ Ke8

The only move. Any other loses immediately.

7.Qxg4 Qf6

The correct reply is 7...Nf6

8.d4 Bh6 9.0-0 Qg7 10.Qh5+ Ke7 11.Bxf4 Bxf4 12.Rxf4 Nf6 13.Qh4 d6 14.Nc3 c6 15.Raf1 Rf8 16.Nf7

16.Nxc6+ would equally have won, but I could not resist this; it is the sort of move sure to intimidate the ordinary amateur. Anyway it somewhat non-plussed my opponent, for he immediately exclaimed, 'What have you taken?'

16...Rxf7 17.e5 dxe5 18.dxe5 Nbd7 19.exf6+ Nxf6 20.Ne4 Be6 21.Nxf6 Kf8 22.Nxh7+ Kg8 23.Rxf7 Bxf7 24.Nf6+ Kf8 25.Qb4+

How's that, umpire?

Wilder!

Taking the lead from Pete Banks (see "Wild!") I stopped by the Lolli Gambit (aka Wild Muzio) tournament on Chessworld.

He was right: I found a number of quick wins for White, including ten (so far) that followed the same line: 1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. Bxf7 Kxf7 6. Ne5 Ke8 7. Qxg4 d6 8. Qh5 Ke7 9. Qf7 checkmate.

There was another game that was even shorter: 1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. Bxf7 Kxf7 6. Ne5 Ke6 7. Qxg4 Kd6 8. Nf7 Black resigns.

Obviously the Wild Muzio has some "shock and awe" impact.

It's also pretty double-edged, as I noticed some quick wins by Black, in 11, 13 and 14 moves.

Clearly this opening and the Chessworld site are worth a closer look.

In the meantime, here's a bit longer Lolli Gambit win from my database, between two players from the Ukraine:

Nasikan - Pasemko
12th Stepichev Memorial
Kiev, 2004

1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.Bxf7+ Kxf7 6.Ne5+ Ke8 7.Qxg4 Nf6 8.Qxf4 d6 9.Nf3 Bg7

Better is 9...Rg8, according to Polerio – and Fritz 8.

10.0-0 Kf8

This idea seems a bit extravagant and leads to an equal game, whereas 10...Nc6 seems to hold Black's edge.

11.d4 Kg8 12.e5 dxe5 13.dxe5 Nd5 14.Qg3 h6 15.c4 Nb6 16.b3 Nc6 17.Bb2 Be6 18.Nc3 Bxc4

Playing with fire. Wiser was 18...Kh7.

19.Rad1

Why not simply 19.bxc4 ?

19...Qe7

Sealing his doom: withdrawing the en prise Bishop with 19...Bd5 was best.

20.bxc4 Nxc4

After this White either wins the Black Queen or checkmates his opponent.

21.Nd5 Qc5+

This allows mate. 21...Ne3 may be "best", as it "only" leads to the loss of the Queen

22.Kh1 Nxb2

Or: 22...Qxd5 23.Rxd5 Ne3 24.Rd7 Nf5 25.Qg6 Rh7 26.Qxf5 Rf8 27.Qg6 Ne7 28.Rxe7 c5 29.e6 Kh8 30.Bxg7+ Kg8 31.Bf6+ Rg7 32.Qxg7 checkmate

23.Nf6+ Kf7

Or: 23...Kf8 24.Nd4 Nxd4 25.Nh5+ Ke8 26.Qxg7 Kd8 27.e6 Qd6 28.Qxh8+ Ke7 29.Qf6+ Ke8 30.Ng7 checkmate

24.Nd7

Quicker: 24.Nh4 Nd3 25.Qg6+ Kf8 26.Nd7+ Ke7 27.Qxg7+ Kd8 28.Nxc5 Kc8 29.Qxh8+ Nd8 30.Rxd3 a6 31.Qxd8 checkmate

24...Qe7

"Better": 24...Rhf8 25.Nxc5 Nxd1 26.Rxd1

25.Nh4+ Ke8 26.Qg6+ Kd8 27.Nb6+ Nxd1 28.Rxd1+ Qd6 29.Rxd6+ cxd6 30.Qxd6+ Ke8 31.Nxa8

White has his win in mind, and so misses the faster: 31.Qe6+ Ne7 32.Nf5 Bf8 33.Nd6+ Kd8 34.Qd7 checkmate

31...Bxe5 32.Nc7+ Kf7 33.Qe6+ Kg7 34.Nf5+ Kf8 35.Qe8 checkmate

Wild!

A discussion started in "London Calling... Seven Months of Blog", (is there another totally obscure and disreputable tactical opening line or gambit that I could go digging for information about, while I'm researching the Jerome Gambit?) eventually led to a comment by chessfriend and Jerome Gambit Gemeinde member Pete Banks ("blackburne") to the post "Worth a Second Look... (Part 1)"


Rick,

I've just started a
Lolli Gambit (aka Wild Muzio) tournament on Chessworld. It's similar to the Jerome in that a Bishop is sacced very early on f7. 1.e4 e5 2.f4 ef 3.Nf3 g5 4.Bc4 g4 5. Bxf7ch?! It seems to have more potential for quick wins than the Jerome. there have been several wins for White in under 10 moves already.

Pete



Now that's wild!

I did some quick research to learn more about Pete's suggestion, and ran into this game attributed to Greco:

Greco,G - NN, Europe, 1620
1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.Bxf7+ Kxf7 6.Ne5+ Ke6 7.Qxg4+ Kxe5 8.Qf5+ Kd6 9.d4 Bg7 10.Bxf4+ Ke7 11.Bg5+ Bf6 12.e5 Bxg5 13.Qxg5+ Ke8 14.Qh5+ Ke7 15.0-0 Qe8 16.Qg5+ Ke6 17.Rf6+ Nxf6 18.Qxf6+ Kd5 19.Nc3+ Kxd4 20.Qf4+ Kc5 21.b4+ Kc6 22.Qc4+ Kb6 23.Na4
checkmate

Anyone whose King has been hounded to death while facing the Jerome Gambit will sympathize with poor NN, above.

From http://wapedia.mobi/en/Giambattista_Lolli:

Giambattista Lolli (1698 in Nonantola, Italy- 4 June 1769) was an Italian chess player. Lolli was one of the most important chess theoreticians of his time. He is most famous for his book Osservazioni teorico-pratiche sopra il giuoco degli scacchi (English: Theoretical-practical views on the game of chess), published 1763 in Bologna. It contains analyses of chess openings, in particular the Giuoco Piano. In the King's Gambit the variation 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5. Bxf7+ is designated after Lolli. It illustrates the Italian masters' style of uncompromising attack, which clearly differs from the rather more strategic considerations taken by, for example, the French chess player Philidor. In addition, the book contain listings of 100 chess endgames. One of these positions was used by Wilhelm Heinse in his novel Anastasia und das Schachspiel (English: Anastasia and the game of chess).

W. John Lutes' fantastic Cunningham Gambit (1980) (anything written by Lutes is fantastic - he was a relentless researcher) has an in-depth history of the King's Gambit, and it's worth tracing the Wild Muzio a bit.

One such series of Italian manuscripts were written by the brilliant analyst and player, Giulio Cesare Polerio, around 1590. He had accompanied Leonardo da Cutri to Spain in 1575 and had first-hand knowledge of the opening analysis done by the Spanish players. As well, his recorded variations and comments show that he had both played and analyzed the King's Gambit for some time.

Polerio discusses the King's Gambit at considerable length and a few examples are necessary to illustrate the extraordinary depth of his play... 1.e4 e5 2.f4 ef 3.Nf3 g5 4.Bc4 g4 5.Bxf7+ Kxf7 6.Ne5+ Ke6 7.Qxg4+ Kxe5 8.Qf5+ Kd6 9.d4... ["And although he has lost two pieces, yet he will win the game by force from the given position, provided he knows how to go on with the attack. If Black observes the loss of the game after 6...Ke6, and does better, perhaps by 6...Ke8!, then 7.Qxg4 Nf6 8.Qxf4, and seeking to Castle, White will have the best attack, despite having lost a piece for severals Pawns, as Black can no longer Castle."]

In a footnote, Lutes adds

5.Bxf7+ is presently known as the Lolli Muzio Gambit, from its having appeared in the Osservazioni Teorico-pratiche sopra il Giuoco degli Scacchi; ossia Il Giuoco degli Scacchi..., 1763, written by Giambatista Lolli.

Polerio's observation that the best defense is 6...Ke8! 7.Qxg4 Nf6! (7...Qf6 was Lolli's idea) was borne out by extensive analysis by Zukertort (1868), Schmid (1886), Alapin (1889), and Savenkoff (1897). The main line runs: 8.Qxf4 d6 (8...Bd6 [Zukertort, 1868] 9.0-0 Rf8! 10.d4 Nc6 11.Qh6!, gives White a strong attack. Analysis by Paul Bohl, 1884; Alapin, 1899; and Savenkoff, 1897) 9.Nf3 (9.Nc4 Nc6 10.0-0 Bg7 11.d3 Be6 12.Qg3 Qe7. -/+. Allgaier, 1802) Rg8! 10.e5 de 11.Nce5 Bd6 12.0-0 Bh3 13.Re1 Bc5+ 14.d4 Bxd4+ 15.Be3 Rxg2+ 16.Kh1 Rg4! -/+. Dr. C. Schmid: Deutsche Schachzeitung, 1886, p. 325.

The Lolli connection shows up later, after several authors, including Greco

With Greco, the King's Gambit became a fearsome weapon of attack. He whipped together the best analysis of the old Italian masters and hammered out a system of uncompromising assault on the enemy f7 square; sacrificing as many Pawns or pieces as necessary to achieve this objective...

According to Lutes,

Lolli took Ercole del Rio's bare analysis from the Sopra il giucco delgi Scacchi..., 1750, and added copious notes and explanations; as well as a few well chose contributions. The following variations from Lolli are of interest: (A) 1.e4 e5 2.f4 ef 3.Nf3 g5 4.Bc4 g4 5.Bxf7+ Kxf7 6.Ne5+ Ke8! 7.Qxg4 Qf6 8.Qh5+ Ke7 9.Nf7 Qxf7 10.Qe5+ Qe6 11.Qxh8 Nf6 12.b3 Nc6 13.Bb2 Ne5 14.Nc3 c6 15.0-0-0 (K at b1 and QR at e1) Qf7 16.Nd5+ cd 17.ed Bg7 18.Rxe5+ Kd6 19. Qd8 b6 20.d4 Bb7 21.Ba3 mate...

Again, playing through the analysis, it's hard not to see themes that show up in the later Jerome Gambit.
