Jackal Attack Games

(1) Skelton,A - Kelly,B [C11] Belfast League, 1990 [Adrian Skelton] The game now takes an interesting twist. 10...g5 11.Bg3 g4 This weakening of the pawn structure can easily rebound on Black. 12.Nh4 Ncxe5 13.Bb5 Nc6 14.Re1 Ne7 15.Qxg4 Rg8 Should White retreat the Queen? No definite answer could be reached so .... 16.Qxg8+!? It is not possible to calculate such sacrifices exactly, nor necessary. It is enough to see that White will have a very active attack and will pick up additional material along the way. 16...Nxg8 17.Nxd5 Bxf2+ 18.Bxf2 Qa5 19.b4 Qd8 20.Bg3 Kf8 21.Nc7 Rb8 22.Rad1 Ngf6 23.Rxe6 a6 24.Bxd7 Bxd7 25.Red6 Qxc7 26.Rxf6 Qxc2 and Black soon resigned. 1-0

(2) Skelton,A - Jestadt,J [C11] Internet Blitz Belfast, 2001 1.e4 e6 2.Nc3 d5 3.Nf3 Nf6 4.e5 Nfd7 5.d4 c5 6.Bg5 Qb6 7.dxc5 Bxc5 8.Qd2 Bxf2+ 9.Qxf2 Qxb2 10.Kd2 Qxa1 11.Bb5 Qxh1 12.Qc5 Qxg2+ 13.Kc1 Qxg5+ 14.Nxg5 Na6 15.Qd6 h6 16.Nxe6 [Better was - 16.Nxd5 exd5 17.e6 Nac5 18.Bxd7+ Bxd7 19.exf7+ Kd8 20.f8Q+ Wins!] 16...fxe6 17.Qxe6+ Kd8 18.Qd6 Re8 19.e6 Nac5 20.exd7 Nxd7 21.Nxd5 Re1+ 22.Kd2 Re5 23.Qc7+ Ke8 24.Bxd7+ 1-0

(3) Gerona Maura,Jesus (2026) - Garcia Molla,Victor Manuel (2278) [C11] Cullera op 25th Cullera (9.13), 30.07.2005 [Adrian Skelton] This is a very interesting exchange sacrifice in the Jackal Attack in a game played last year. I doubt many human players would even consider 15.Be7!! which was possible early in the game. The whole course of the game is interesting. Adrian 1.e4 e6 2.Nf3 d5 3.Nc3 Nf6 4.e5 Nfd7 5.d4 c5 6.Bg5 Qb6 7.dxc5 Bxc5 8.Qd2 Bb4 9.a3 Qa5 10.axb4 Qxa1+ 11.Nd1 Nc6 12.Bb5 a6 [Alternatively; 12...0-0 13.0-0 a6 (13...Ndxe5 14.Nxe5 Nxe5 15.Nc3 Qxb2 16.Rb1 can lead to a repetition of moves.) 14.Bxc6 bxc6 15.Nc3 Qxb2 16.Rb1 Qa3 17.Qe1 threatening- 18Rb1-b3 gives White the advantage.] 13.Bxc6 bxc6 14.0-0 Qa4 [14...Qa2 15.b3 remains unclear;eg. 15...Rb8 16.Nd4 Nxe5 17.Bf4 f6 18.Bxe5 fxe5 19.Nxc6 Rb7 20.Nc3 Qa3 21.Nxd5! appears to be winning.] 15.Nd4 Here, after 14...Qa1-a4, White has missed a very strong and shocking move. [15.Be7!! I discovered this having reached this position before in a five minute game on the internet although (not surprisingly) I missed it during the game). If now 15...Kxe7 White wins by (15...Qb5 ) 16.Nc3 Qxb4 17.Nxd5+ winning Black's queen. Alternatively 15...Qa4-b5 [Or 15...c6-c5 16.Qd2-g5] 16. Qd2-g5 is winning against both 16...g7-g6 17.Be7-d6 or 16...Rh8-g8 when again 17.Be7-d6 f7-f6 18.Qg5-h5 is too strong.] 15...c5 16.bxc5 Nxc5 17.b3 Qd7 18.Qa5 Nb7 19.Qb6 h6 20.Bh4 g5 A dubious expansion that harms Black more than White. 21.Bg3 Nd8 22.Ne3 Qa7 23.Qb4 a5 24.Qd2 Ba6 25.Ra1 h5 26.h4 g4 27.Rxa5 Qb8 Care is always needed when placing the queen in line with the enemy bishop. Here, it marks the beginning of the end. 28.Nxd5 exd5 It would have been prudent not to have taken the piece. 28...Kf8 was better although White would have retained a definite advantage.) 29.e6 Qb7 30.Nf5 Qa7 31.Nd6+ Kf8 32.Nb5 Bxb5 33.Rxa7 Rxa7 34.Qb4+ Kg8 35.e7 Ne6 36.Qxb5 Rxe7 37.Be5 Rh6 38.Qb8+ Kh7 39.Qh8+ Kg6 40.Qf6+ 1-0

(4) RoyChowdhury,S (2400) - Yuferev,O (2400) [C11] 2006 [Skelton] 1.e4 e6 2.Nf3 d5 3.Nc3 Nf6 4.e5 Nfd7 5.d4 c5 6.Bg5 Qb6 7.dxc5 Bxc5 8.Qd2 Nc6 9.0-0-0 Qa5 10.a3 a6 11.Kb1 0-0 12.Bf6 Nxf6 13.exf6 gxf6 14.Qh6 Ne7 This position is known from the e-book. White has a standard winning plan. 15.Qxf6? [15.Bd3 Ng6 16.h4! White plans to force open the h file. 16...Rd8 17.Ng5 fxg5 18.hxg5 Nf8 19.Bxh7++- ] 15...Qc7 16.Ne2 Ng6 17.h4 Be7 18.Qc3 Qxc3 19.Nxc3 Bf6 20.Na4 b5 21.Nc5 Ra7 22.h5 Ne5 23.Nxe5 Bxe5 24.g3 Bd6 25.Nd3 a5 26.f4 Bd7 27.Ne5 Be8 28.Nf3 Rb7 29.Bd3 Bd7 30.Ne5 Rfb8 31.Nxd7 Rxd7 32.Rhf1 b4 33.a4 f5 34.Rde1 Kf7 35.g4 fxg4 36.Bxh7 Kf6 37.Bg6 b3 38.c3 Rc8 39.Rd1 Bf8 40.Rg1 Rc4 41.Rxg4 Bh6 42.Bd3 Rxf4 43.Rg6+ Ke5 44.Rxh6 Re7 45.Re1+ Kd6 46.Rg6 1-0

(5) Rutter,Nick - Morgan,Ben [C11] Shropshire v Cambridge, 31.05.2008 [Skelton/Rutter] 1.e4 e6 2.Nf3 d5 3.Nc3 Nf6 4.e5 Nfd7 5.d4 c5 6.Bg5 Qb6 7.dxc5 Bxc5 8.Qd2 Nc6 9.0-0-0 Bb4 10.a3 Bxc3 11.Qxc3 This position is analyed extensively in the Jackal Attack e-book. 11...Nc5 12.Be3 Ne4 13.Qe1 Qc7 14.Kb1! This is quite a useful move as it removes the king from the c-file and sets up possibilities of c2-c4 so as to destabilize Black's centre. 14...Bd7 15.Bd3 [15.c4!? ] 15...Nxe5 Although it is possible to win a pawn, Black really needed to castle at around this point. 16.Bxe4 dxe4 17.Nxe5 Qxe5 18.Qb4 Now Black's inability to castle and dark square weaknesses are serious problems that plague him for the remainder of the game. The opposite coloured bishops are a distinct disadvantage with the heavy pieces still in play. 18...Bc6 19.Bd4 Qg5 20.h4 Not just depriving Black of another dark square: This pawn can cause further difficulties if allowed to advance too far. 20...Qh6 [After 20...Qe7 21.Bc5 Qf6 22.g4 is good.] 21.Qd6 Now Rd8 loses to Qxd8+ 21...Bd5 22.Be3 Stronger than 22.c4 22...Qg6 23.h5 Qf5 24.Bc5 [24.h6! was the most accurate. For instance: 24...Rd8 25.hxg7 Rg8 26.Qg3+/- ] 24...Qg5 25.h6 gxh6 [It is difficult to defend under these circumstances. The best hope was 25...g6 But now White would have a winning attack with 26.f4! Qd8 27.Rxd5! exd5 28.Qe5+ Kd7 and here 29.Rd1 illustrates Black's plight. The h6 pawn gives White a win in any simplified rook ending. Meanwhile... 29...Kc6 30.Qc3 (Or White might prefer 30.Be7 Qd7 31.Qc3+ Sample line: 31...Kb6 32.Qc5+ Ka6 33.Rxd5 Qa4 34.b3+- ) 30...Kb5 31.Qb4+ Kc6 32.Be7 and it is over.] 26.Rxh6 Rd8 27.Rxd5 1-0

(6) Soozankar,A (2221) - Hassan,A (2352) Dubai Op 10th, 2008 [Skelton] 1.e4 e6 2.Nf3 d5 3.Nc3 Nf6 4.e5 Nfd7 5.d4 c5 6.Bg5 Qb6 7.dxc5 Bxc5 8.Qd2 Nc6 9.0-0-0 a6 10.Na4+/= Qc7 11.Nxc5 Nxc5 12.Qe3 b6 [12...Ne4 seems a bit more active. But after either 13.Kb1 or 13.Bh4 White should probably be slightly the happier of the two sides. Sample line: 13.Kb1 Nxg5 (13...h6 14.Bh4 g5?! would only give rise to later problems.) 14.Qxg5 0-0 15.Bd3 h6 16.Qh5 Bd7 17.g4|^ and we know where that is heading.] 13.h4 Looks like a fair attempt: If the pawn gets to h5 then White's bishop will nestle into h4 if attacked. Thereafter, Black can wave goodbye to any chances of later sneaking his king over to the safety of the queenside. [13.Kb1 Bb7 14.h4 seems level since White has yet to find a way of disturbing the position to the advantage of the bishop pair.] 13...Bd7 [13...h6 was probably best. 14.Bf4 Bb7 15.Kb1= ] 14.h5 h6 Too late. 15.Bh4 a5 [15...Rc8 16.Kb1 and White's position is now to be preferred. Black's king can no longer castle safely.] 16.g4 a4 17.a3 d4 After this, the position begins to open up to White's increasing advantage. 18.Qe1! d3 [18...Rb8 maybe] 19.Bxd3 Na5 20.Nd4 [20.Qb4 was well worth a look; though there are other moves.] 20...Nxd3+ [20...Nab3+ Getting rid of the a5 knight looks better. 21.Nxb3 axb3 22.c3 Nxd3+ 23.Rxd3+/- ] 21.Rxd3 0-0 Black never recovers from this and his position rapidly deteriorates. But in any event, after say, 21...Nb3 22.Nxb3 axb3 23.Rxb3 castling would meet with the same general response. 22.g5-> hxg5 23.Bxg5 f6 [23...Rfc8 24.h6 Nb3+ 25.Rxb3 axb3 26.hxg7+- ] 24.exf6 e5 25.fxg7 [Or 25.h6 ] 25...Kxg7 26.Qe4 Qd6 27.Nf3 [27.Nb5 is amongst others.] 27...Bc6 [27...Bf5 28.h6+ Kh7 29.Qxa8+- ] 28.Qg4 Bxf3 The Jackal bishop is given the last word. 29.Bf6+ with a forced mate. 1-0
