IECC Jottings #7 9th March, 1997 Editor: Gordon Lee Publisher: Lisa Powell Contributor: Conrad Goodman Bill Wall Phil Hidenbrandt Sorry about the delay everybody. I was busy with my school work and didn't have time to write Jottings. So, well, here it is! Enjoy. If you have any articles you would like to submit, please send them to . They will have a very high chance of getting published. My thanks again to IM Conrad Goodman for writing another excellent article. Improving Your Chess Instinct .. part 2 ======================================= by IM Conrad Goodman CREATE DIVERSION .. This can be accomplished easier in 2-game matches. One strategy is to play for 1.5 points. Try to gain the advantage in one game which forces your opponent to focus on that troubled game. This might let you gain an advantage in the other game as well .. and if you know that your opponent is playing many opponents .. reply as fast as you can to maintain the pressure. CREATE TIME PRESSURE .. Offer if moves whenever you have an advantage .. also if it can add time pressure to your opponent's clock or can help reduce your 10@30. The 10@30 time control simply means each player's last 10 moves must be made within 30 cumulative days .. starting at moves 1 thru 10 .. then 2 thru 11 .. then 3 thru 12 etc .. which averages out to be 3 days per move. Under the 10@30 time control .. players may not take more than 10 days to answer one move. If you can get your opponent to take 5 days on a move .. then 5 more days on the next move .. that leaves 20 days for your opponent to make the remaining 8 moves within that 10 move bracket. It will also take your opponent 10 more moves to clear away each of those 5 day counts!! Send a standard repeat on the 3rd day you are waiting for a reply. This serves as a reminder and tells an opponent .. " your clock is ticking and I am thinking on your time .. " STAY ALERT .. Play as many opponents as you can comfortably handle .. because playing too few games can make one's thinking sluggish .. while waiting for moves to arrive. AVOID SPENDING EXCESSIVE TIME ON A MOVE .. Review the incoming move at several different sittings .. and make notes. The stronger one gets, the fewer lines need be considered. In short .. the more up front thinking that's done .. the faster one should be able to reply to moves .. usually within 1 day of receipt. TRY PROGRESSIVE MOVE ANALYSIS .. If you have an idea, simply move pieces to appropriate squares .. then formulate the best sequence of moves to achieve that idea. KNOW WHEN TO RESIGN .. One saying goes .. " Winner's never quit .. and quitters never win .." another one goes .. " Play the person .. as well as the position .." So .. here's some criteria to consider: a. If playing a two game match and ahead in one game .. try to put more pressure on the 'good' game .. and keep the 'bad' game going to frustrate the opponent. b. If the 'bad' game can possibly be saved .. via perpetual check .. stalemate .. or won on the clock .. keep it going by all means. c. However .. when a bad game simply eats up too much study time .. and appears hopeless .. get rid of it. Here are some more recently completed games without analysis .. as the games speak for themselves ..

However, Jorge felt this move was an error for white. 25.Be5 was the position white had played for .. a mating attack with bishop, knight & queen. Ahead pawns .. black still has to be careful. for example .. here's only one line of analysis based on 'what if black plays 30 .. Bg6' instead of Qd2.

Note: The above game was a friendly match between the Team Captains of ASIGC and PCSI. More tips and games to appear in coming articles. ---------------------------- Simple Endings ============== To fill in the request for endings. I am going to start and write about the most basic endings. The Opposition -------------- Let's imagine that you have just a pawn left in the ending. Where do you think the king would be best placed to take advantage of this? The answer is in front of the pawn, the reason for this is because of the opposition. Put the White king on b1 and Black's on b8. It might surprise you in saying that the White king can force his way to c8 using only a,b and c files. Illustration 1 -------------- Pos: WK-b1 BK-b8 1.Kb2 Kb7 2.Kb3 Kb6 3.Kb4 [White has obtained the opposition since the kings are directly opposed and neither can advance. Black, however must move and have to let the White pass by stepping aside] 3...Ka6 4.Kc5 Kb7 5.Kb5 [The Opposition again!] 5...Kc7 6.Ka6 Kb8 7.Kb6 [And again!] 8.Ka7 Kc7 9.Ka8 --------------- Now if Black does not advance first... Illustration 2 -------------- Pos: WK-b1 BK-b8 1.Kb2 Ka8 2.Kb3 Kb7 3.Kb4 Kb6 [Now BLACK have the opposition, white can make no progress] 4.Ka4 Ka6 5.Kb4 Kb6 6.Kc4 Kc6. --------------- Hence a player is said to have the opposition when the kings are opposing and it is his opponent's turn to move. With correct play, White can take and hold the opposition through out if he/she remembers two points. 1, When Black's king moves to a square on the central file (in this case the b-file), then White moves on to a square on the same colour on the same file. 2, If Black goes sideways to the a or c file, then White should advance to the other file, this is known as by-passing. Illustration 3 -------------- Pos: WK-b1 BK-b8 1.Kb2 Ka8 2.Kc3 [by-passing..] 2...Kb7 3.Kb3! [obtaining the distant oppositon] 3...Kc8 4.Ka4 [still by-passing] 4...Kc7 5.Ka5 Kb7 6.Kb5 Kb8 7.Kb6 [when White reaches a8 or c8] --------------- To see why the opposition is so important, look at the next example Illustration 4 -------------- Pos. WK-f6 WP-f5 BK-f8 [If Black to move first, the win is easy as White has the opposition immediately. 1...e8 2.Kg7 ..etc. While with White to move first] 1.Ke6 Ke8 [Other moves allow 2.Ke7 +-] 2.f6 [Winning since White has now gained the opposition and has a position similiar that have the previous examples] 2...Kf8 3.f7 Kg7 4.Ke7 wins --------------- Illustration 5 -------------- Pos. WK-b1 WP-b4 BK-b8 [White's pawn is already on the fourth rank and the White King has no chance of getting in front of the pawn in order to win the opposition.] 1.Kb2 Kb7 2.Kb3 [gaining the distant opposition] 2...Kb6 [Now white can't keep the opposition as he can't play Kb4] 3.Kc4 Kc6 [Black has gained the opposition and White must give up all hope of getting his king in front of the pawn] 4.b5+ Kb6 5.Kb4 Kb7! 6.Ka5 Ka7 7.b6+ Kb7 8.Kb5 Kb8! [Other moves loses] 9.Kc6 Kc8 1/2 --------------- Illustration 6 -------------- Pos. WK-g1 WP-g2 BK-g8 [Now let's see what happen if the White King can get in front of the pawn] 1.Kf2 Kf8 [Maintaining the distant opposition] 2.Kg3 Kg7 3.Kg4 Kg6 [Where Black has kept the opposition, but White has a pawn!] 4.g3! [Now the boot is on the other foot!] 4...Kg7 5.Kg5 Kf7 6.Kh6 [By-passing, not 6.g4 where Kg7 Black would have kept the opposition and would draw] 6...Kg8 7.g4 Kf7 8.g5 Kg8 9.Kg6 1-0 --------------- Having considered those two examples we should note that, in Ill. 5, White could not get his king in front of the pawn and should be content with the draw. Whereas in the second case he did manage to get his king he front of the pawn. When faced with the opposition, he had a pawn move to counter it. I hope that this is helpful to your play, good luck! ------------------------- Chess and Sport =============== >From William Harston's hilarious "How to cheat at chess" As the pavilion clock comes up to the hour the umpires are emerging in their familiar white coats to assess the prospects of play. They are walking slowly to the board, but it lloks from here that all the pieces are in place and I think we should soon see the openers coming on to the stage. The big crowd applauds the entry of Spassky and Fischer as they take their stance at the opposite end of the big board. Fischer has won the toss and will open from the White end. He gets ready to take the pawn between his fingers. He gives a hostile glare as he comes in to move and digs the pawn into the board. Spassky's seen it well and judged its path perfectly; it's a four: pawn to king four. And there appears to be a hold-up in play; I think Fischer has appealed against the light. Fischer's on top in the middle-game now and hoping for an early submission. He's got Spassky in a Maroczy bind and the Russian's clearly suffering. Spassky looks appealing at the clock; he has only to last until the adjornment to refresh himself before the next round. Fischer hammers down another blow but his opponent is holding on. With a lightning-swift move Spassky breaks the Maroczy bind and it's bell for the end of the middle game. With only White and Black left on the table, "Battling" Boris is taking a long cool look at the position of his remaining pieces. He walks slowly around the table, examining all the angles before deciding on the next shot. With perfect confidence he plays his queen off the far cushion to pot another black pawn. And as the referee blows his whistle for the adjornment,Spassky passes the pocket set to Geller wearing the no.2, who passes it to Bondarevsky. It is Bondarevsky back to Geller, Geller to Spassky who keeps the possession of the set taking it smoothly out of the door and into the toliet and back into the room again. never losing possession, keeping his concentration and control all the time. And Geller has taken the set; Geller to Bondarevsky who is dribbling up the centre. It's a foul! The referee has blown his whistle for a foul habit. And as they enter the final furlong, it's Spassky, owned by Brezhnev and Kosygin and trained by Bondarevsky, still in the lead by three pawns but he is looking tired, very tired, extremely, very very tired and Fischer has the better finish. Yes, the gap is closing, it's closing, it is definitely closer. Fischer is catching up... two pawns behind now.. Fischer is coming up fast... only one pawn behind... They are now neck and neck! And at the post it is a dead heat - It's a draw, Fischer 1/2 Spassky 1/2 --------------------- Traps in the Ruy Lopez, Exchange Variation ========================================== by Bill Wall The Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5) is one of the oldest openings and has many traps for both sides to be careful of. After 1.e4 e5 2.Nf3 Nc6 3.Bb5, Black need not fear 4.Bxc6 and 5.Nxe5. For example, in the exchange variation, 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.Nxe5, Black simply plays 5...Qd4, threatening the knight at e5 and the pawn at e4. White should continue his development and castle instead. Game 1 ------ 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O. If Black tries 5...Nf6, then 6.Nxe5 Bd6 7.Nc4 Nxe4 8.Qe2 Qe7 9.Re1 Nf6 10.Nxd6+! cxd6 11.Qxe7 mate (Moore-Peto, British Columbia 1980) Game 2 ------ 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Nf6 6.Nxe5 Nxe4, White has the following: 7.Re1 Qd4 8.d3 Qxf2+ 9.Kh1 Nf6 10.Ng4+, winning the Queen (Wall-Flygare, Postal 1995) Another idea for Black is.... Game 3 ------ 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Bd6 6.d4 Bg4 7.dxe5. Now Black should play 7...Bxf3. If 7...Bxe5? 8.Qxd8+ Kxd8 9.Nxe5 wins a piece (Bradley-Bath, Ohio 1978) Game 4 ------ 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Bd6 6.d4 Qf6 is too dangerous. After 7.Bg5 Qe6 8.dxe5 h6 9.exd6 Qxd6 10.Bh4, White is up a piece (Wall-Ellena, San Antonio 1970) Another idea is 5...Qd6 instead of 5...Bd6 Game 5 ------ 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Qd6 6.d4 Bg4 7.Bg5 f6 8.Be3 O-O-O 9.h3 h5 10.hxg4 hxg4 11.Nh2 exd4 12.Bd2 Qxh2 mate (Duncan-Wall, Dayton 1984) Game 6 ------ [After] 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O [popular is] 5...Bg4 [Black needs to be careful.] 6.h3 Bh5 7.g4 Bg6 8.Nxe5 Bxe4 9.Re1 Qd5 10.Nc3 Qxe5 11.Rxe4 wins (Wall-Henline, North Carolina 1977) Game 7 ------ [Instead of 6...Bh5, Black can play ]1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Bg4 6.h3 h5!? [White should not play] 7.hxg4? [better is 7.d3] hxg4 8.Ne1 Qh4 9.f3 g3 and 10...Qh2 mate (Garner-Rowland, Arkansas 1979) Game 8 ------ 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Bg4 6.h3 h5 7.d3 Qf6 8.Nbd2 Ne7 9.Re1 Ng6 10.Qe2?! (better is 10.d4) 10...Bc5 11.hxg4? Nf4 12.Qd1 hxg4 13.Nb3 Qh6 wins (Gonzales-Dyke, Los Angeles 1976) [Instead of 8.Nbd2, White can also play 8.Be3. But after 8...Ne7 9.Nbd2 Ng6 10.hxg4 hxg4 11.Ng5 Nf4 12.Qxg4 Qxg5! Black wins after 13.Qf3 (13.Qxg5 Ne2 mate) 13...Qxg2+ 14.Qxg2 Ne2 mate (Bohm-Hernandez, Amsterdam 1979)] Game 9 ------ [Black can try to defend his e-pawn with f6.] 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O f6. [White can continue, ]6.d4 exd4 7.Nxd4 [and if]7...Bc5?? 8.Qh5+ and 9.Qxc5 wins a piece (Foley-Hoffman, Ohio 1979) Game 10 ------- 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O f6 6.d4 exd4 7.Nxd4 c5 8.Nb3 Qxd1 9.Rxd1 Bd6 10.Na5, now 10...Bg4? is bad (better is 10...b5). After 11.f3 O-O-O 12.e5! (and not 12.fxg4? Bxh2+ 13.Kxh2 Rxd1), White wins (Hort-Zheliandinaov, Havana 1967) If 9...Bd7 istead of 9...Bd6, then 10.Bf4 O-O-O 11.Nc3 c6 12.Na4 b5 13.Nb6+ Kb7 14.Nxd7, winning a piece (Glass-Bauer, Switzerland 1977) ------------------------- Games of the Week ================= [Event "Pyramid"] [Site "IECC"] [Date "1996.??.??"] [Round "1"] [White "Ma Whee Ky"] [Black "Cohen Harry"] [Result "1-0"] [ECO "B12/01"] [WhiteRating "2594"] [BlackRating "2191"] 1.e4 c6 2.d4 d5 3.f3 e6 4.Be3 dxe4 5.Nd2 exf3 6.Ngxf3 Nf6 7.Nc4 Be7 8.Bd3 Nd5 9.Bd2 O-O 10.h4 Nd7 11.Nce5 N7f6 12.Ng5 Qb6 13.c3 Qxb2 14.Rb1 Qxa2 15.c4 Nc7 16.O-O h6 17.Rf3 hxg5 18.hxg5 Nce8 19.gxf6 Nxf6 20.Rxf6 Bxf6 21.Bc3 Bg5 22.Qh5 Be3+ 23.Kh1 f5 24.Ng6 Bh6 25.g4 Qf2 26.g5 Bxg5 27.Qh8+ Kf7 28.Ne5+ Ke8 29.Qh5+ Kd8 30.Qxg5+ Ke8 31.Qg6+ Kd8 32.Qxg7 Qh4+ 33.Kg2 1-0 ------------------------- Fried Liver Attack ================== by Phil Hildenbrandt Whenever one plays the Two Knights defence, he has to decide if the Fried Liver Attack will be played. A dangerous attack can be had after 4.Ng5 if Black does not play accurately. White should be ready for the Willkes-Barre (Traxler if you prefer) if Black answers with 4...Bc5, which is his best answer. Still, it takes nerves of steel to play any variation arising out of the Willkes-Barre. The following game I played was very heartbreaking to lose but I learned never to play 12.Bb5+ in the Willkes-Barre.
