Tactics, Tactics, Tactics

Staff of Kopec's Chess Camp with GM Lubomir Ftacnik and Irina Krush (second and third from the left) after their match in Lawrenceville NJ, July 1999.

About nine years ago I had the privilege of being a staff member at Kopec’s Chess Camp in Lawrenceville, NJ. One of my responsibilities was to serve as Arbiter in the match between GM Lubomir Ftacnik (Slovakia) and 15-year-old rising star Irina Krush. I also provided chauffer services to the combatants, which included lunch at a local Chinese restaurant with Irina and a trip to Newark Airport with GM Ftacnik while he awaited his flight back to Prague.

We had a few hours to kill, so Lubo asked me to show him some of the sights along the way. I agreed to take him to Princeton in exchange for a brief chess lesson. After walking the university campus, he asked to stop somewhere we could get a good espresso. Coincidently, I knew exactly where to go….a place called Small World Café on Witherspoon Street in Princeton Village. As our conversation turned to chess, I probed for a time when I might get my lesson. “You can have it right now”, he said. “Study more tactics!”.

GM Lubomir Ftacnik-->

“That’s it? More tactics?” I asked. “Actually it’s tactics, tactics and more tactics,” he responded. He went on to say that, as with running, it is necessary to “work out” consistently to gain strength and remain sharp. “The most common deficiency among chess players below expert strength,” he explained, “especially those like you who play a lot of correspondence chess, is in the area of tactics.”

A year later we repeated the same drill and I was eager to show GM Ftacnik my intervening tournament draw against Senior Master Ron Burnett. “That’s a great result,” he said. “But if you had worked hard enough on your tactics during the past year, you would not have agreed to a draw in a winning position.” The game against Burnett has been published elsewhere (ChessCafé.com and one of GM Lev Alburt’s books), so I won’t deal with in in today’s blog.

Nevertheless, the lesson hit home and I have spent the last couple of years delving more deeply into games that I played in the past. Some of the results have been quite revealing…and humbling! Take, for example the contest presented below.

This game is from Round 1 of the 1991 World Open in Philadelphia. Originally, I was very pleased with this game. It was a win against one of the top rated players in my section (under 2000) and it started me off on the right foot in one of my better tournaments. I was playing well, or so I thought at the time.

I understand that this is a game between two class “A” players and, as such, should not be expected to contain much in the area of worthwhile instruction. But, trust me, careful study of the underlying tactics, especially the moves NOT seen by the players during the game, will reveal some of the tactical situations that separate the masters from the masses of tournament chess players. It is well worth your time to follow along with the mental gymnastics if you are serious about improving your game.

Niro (1883) vs. Deschamps (1984)
World Open, Philadelphia, PA
Round 1, Board 308 (!), July 4, 1991
Scandinavian Defense (by transposition) B02

1.e4 Nf6 2.Nc3 d5 3.exd5 Nxd5 4.Nxd5


Regarding the opening, I have never been a fan of either side of Alekhine’s Defense. For a while after the Alburt-Short match (1985) I tried to follow the lines played by GM Nigel Short as White. Somehow I always seemed to come up against players who had memorized the book lines further than I had. Beyond that, the resulting positions were not the type where I felt comfortable. So I started transposing with 2.Nc3 to either the Four Knights (after 2…e5 3.Nf3 Nc6), Three Knights (after 2…e5 3.Nf3 Bb4), Philidor (after 2…e5 3.Nf3 d6), French (2...e6 3.d4 d5) or the Scandinavian (a/k/a The Center Counter Defense) as in this game.

Having said that, the move I usually play after 3…Nxd5 is 4.Bc4. If Black plays the usual 4…Nxc3, then 5.Qf3! forcing 5…e6 before taking the knight on c3 with the queen. It’s a position I have encountered dozens of times with good results over the years. See supplemental games 1-4 for some examples.

On 4.Bc4 Nb6, I always play 5.Bb3 hoping for Rozentalis-Mikenis, USSR 1981 or Vucinic-Djurovic, Yugosalvia 1984 (supplemental games 5 and 6). Curdo-Freeman, Cambridge MA 1957 (!) illustrates
the same line (game 7). The game Kurzdorfer-Men, Erie PA, 1993 is an interesting draw (game 8), White can also deviate a move earlier with 3.e5, Balashov-Alburt, USSR 1974, but that’s an entirely different approach (game 9).

In any case, I chose 4.Nxd5 here for two reasons. First, I wanted to get out the book as quickly as possible to avoid any memorized lines that my opponent might have in his arsenal. More importantly, this path seemed drawish and I was willing to accept a round 1 draw in a long tournament when paired against one of the top players in the section.

4…Qxd5 5.d4

I played 5.Nf3 in an old correspondence game which continued 5…Bg4 6.Be2 Nc6 7.0-0 0-0-0 8.d3 e5 9.h3 Bh5 10.Re1 Bc5 11.Be3 (11.Nxe5! Qxe5 12.Bxh5+) 11…Bxe3 12.fxe3 Qc5 (Niro-Grimsley, corr. 1984, 1/2-1/2, 33).

5…Nc6 6.Nf3 Bg4 7.Be2 Rd8 8.Be3 e6 9.0-0 Bd6 10.c4 Qh5 11.h3 Bf5

Here’s the first tactical position. Black can have a quick draw if he wants by playing 11…Bxh3 12.gxh3 (12.Ne5 Qh4 13.Nf3 Qh5 etc.) 12…Qxh3 13.Re1 Qg4+ 14.Kh1 Qh3+ 15.Kg1 Qg4+ 16.Kf1 Qh3+ 17.Kg1 Qg4+ draw by repetition.

12.d5?

Not the best. 12.c5! wins material. Black cannot retreat the bishop 12…Be7? because of the discovered attack on his queen. 13.Ng5 Qh4 (13…Qg6 14.Bh5 Qf6 15.Nxf7 +-) 14.g3 Qh6 15.Nxf7 +-. Therefore Black must capture the pawn. 12…Bxc5 13.Nd2! (attacking the queen and simultaneously removing the pin…the move I missed) 13…Qg6 (13…Qh4 14.dxc5 Bxh3? 15.gxh3 Qxh3 16.Qb3 +-) 14.Bh5 Qf6 15.dxc5 Qxb2 16.Qb3 Qxb3 (16…Rxd2 17.Bxd2 Qxd2 18.Qxb7 Nd8 19.Qxc7 +-) 17.axb3 Bd3 18.Rfd1 and White has a piece for the pawns, with the queens off the board.

By the way, 12.Ne5 is also better than the move I played. After 12…Qh4 13.Nxc6 bxc6 14.Qa4 (14.Qc1 is not as good after 14…0-0 15.Bg5 Qxd4 16.Bxd8 Rxd8 17.Rd1 Qe5 and Black has the attack, two bishops and a pawn, more than adequate compensation for the exchange) 14…0-0 15.Qxc6. White is a clear pawn ahead and his queen adds coverage to the castled king. As you might expect, the discovered attack on the queen is a powerful tactic.

The main problem with 12.d5? is that it still allows Black to force a draw by capturing on h3 if he chooses. 12…Bxh3 13.gxh3 (13.dxc6 Bxg2 14.Kxg2 Qg4+) 13…Qxh3 14.dxc6 Qg4+ 15.Kh1 Qh3+ 16.Kg1 =. Note that after 12.c5! the capture on h3 doesn’t work because the Black bishop is removed allowing the knight on f3 to interpose. So 12.c5! Bxh3 13.cxd6 Bxg2 14.Kxg2 Qg4+ 15.Kh1 Qh3+ 16.Nh2 Rxd6 17.Rg1 and White has a winning advantage.

12…exd5 13.cxd5 Nb4 (Position below is after Black's 13...Nb4. Click on photo to enlarge.) 14.a3!

Now White has the edge. First of all, 14…Bxh3 no longer works for Black but is still pretty messy. White must play 15.gxh3 because 15.axb4? Bxg2 16.Kxg2 Qg4+ is the same old perpetual. If 15.gxh3, Black plays 15…Nxd5 then 16.Ng5! is good enough for an advantage. The best follow-up to the capture on h3 for Black (and most complicated) is 14…Bxh3 15.gxh3 Qxh3 16.Qd4! (all other moves draw) 16…Nxd5! (decoy) 17.Qxg7! Nxe3 18.Qxh8+ Ke7 19.Qg7 Nxf1 20.Qg5+ Ke8 21.Bxf1 Qxf3 22.Re1+! Kd7 23.Bg2 and despite being two pawns down with opposite colored bishops on the board, White has a clear advantage. Check it out for yourself.

Also playable here, and tactically rich, was 14.Qd4 with a double attack on the a- and g-pawns. After 14...0-0 15.Nh4 c5! (15…Qxe2 16.Nxf5 f6 17.Nxd6 Nc2 18.Qc4 Qxc4 19.Nxc4 Nxa1 20.Rxa1 Rxd5 21.Bxa7 b6 and White is better because after 22.b4 Black can’t play 22…Ra8 due to 23.Bxb6 cxb6 24.Nxc6 forking the rooks) 16.Qxb4 (desperado!) 16…Qxe2 17.Bxc5 Bxc5 18.Qxc5 Be4 19.Rfe1 Qxb2 20.Rad1 b6 (20…Qxa2 21.Rxe4) 21.Qc4 and White is better. Sad to admit it, I don’t remember seeing any of this stuff during the game.

The position has also adopted a profound strategical theme: the isolated queen pawn. Despite the myriad of tactical opportunities, the outcome will revolve around whether Black can capture the isolani before it can advance and wreak havoc.

14…Na6

14…Nc2?! 15.Nd4! Qg6 16.Bh5! Qf6 17.Nxc2 Bxc2 18.Qxc2 +-

15.Qa4+

15.Nd4!? Qg6 16.Nxf5 Qf5 17.Qa4+ Kf8 18.Bxa6 bxa6 (18…Qe5 19.Bf4 Qxf4 20.Qxf4 Bxf4 21.Bxb7) 19.Qxa6 Qxd5 20.Qxa7 Qe5 21.g3 Qxb2 22.Bc5! with advantage for White.

15.Ng5! may have been even better 15…Qh4 16.Rc1 0-0 17.Rc4 Qh6 18.Ne4 g5 (18…Qg6 19.Bh5+-) 19.Bxg5 Qg7 20.Bxd8 Rxd8 21.Nxd6 Rxd6 22.Qd4 Qxd4 23.Rxd4 +-

15…Bd7 16.Qe4+ Kf8 17.Qh4?!

Releasing the pressure. Better was 17.Bxa7 Re8 (17…b6 18.Bxa6) 18.Qc4 b5 19.Qd3 Nc5 20.Bxc5 Bxc5 21.Rac1

17…Qxh4 18.Nxh4 Nc5 19.b4

With the queens gone, play will revolve around White’s isolated queen pawn. Strength or weakness? This will decide the game (with a few tactical skirmishes remaining to muddy the water). Objectively speaking, the game is dynamically equal at this point.

19…Ne4 20.Bd3 Nc3 21.Bc4 b6 22.Rfe1 Be5 23.Rac1

23.Bxb6!? Ne2+ 24.Rxe2 (24.Bxe2 axb6 {24…Bxa1? 25.Bc5+ Kg8 [25…Ke8 26.Bb5+ Be5 27.Rxe5#] 26.Rxa1+-} 25.Rac1+) 24…Bxa1 25.Bxc7 Rc8 26.d6 and the isolani arrives on the 6th rank. It’s progress, but not a win yet.

23…Ba4?

23…Bf6! was correct removing the discovery opportunity.

24.Bc5+?!

Right idea. Wrong direction. 24.Bg5! was the preferred choice. Then after 24…Re8 25.Nf3! is clealry winning.

24…bxc5 25.Rxe5 f6 26.Re6 cxb4


If 26...Nxd5 instead of 26...cxb4, snagging the pawn costs too much after 27.Ra6! Be8 28.Rd1 c6 29.bxc5! +-


Position after 26...cxb4. Click on photo to enlarge.

27.Rce1?!

Bishops move backwards, of course. I wasn’t alert enough to see Black’s bishop covering e8. The way to maintain the advantage was to let the isolani go in exchange for a pawn plus in the endgame. 27.axb4 Nxd5 28.Bxd5 Rxd5 29.Rxc7 Rd7 30.Rxd7 Bxd7 31.Ra6 Ke7 32.Rxa7.

27…b3

27…bxa3 wiping out the may have been better. Then 28.Re7 Nxd5 29.Bxd5 Rxd5 30.Rxc7 leaves Black with the only winning chances in the endame. Maybe I should give my opponent credit for setting a trap.

28.Nf3?

A tactical blunder. The only excuse for the last few errors by both players was the clock. According to the notes on my scoresheet, I had 9 minutes left to make 12 moves and my opponent had 4 minutes left for 13 moves. Still, rooks belong on the seventh rank. Instead I took time to get my knight back in play. This mistake should have cost me the game. My opponent’s time pressure was even worse than mine and it saved me. The right way to go here was 28.Re7! Nxd5 29.Bxd5 Rxd5 30.Rxc7 Rg8 31.Rxa7 Bd7 32.Rb7 Rd3 and be content with a draw.

28…b2! 29.Nd2 Bc2

Black may be objectively winning but his flag is hanging. Another reason for practicing tactics is obvious from this game: you will learn to calculate faster, thus saving time on the clock. Besides the move played, Black has some other good paths at his disposal. 29…Nxd5!? 30.Bxd5 Rxd5 31.Nc4 Rb5 32.Re8+ Kf7 33.Rxh8 b1=Q 34.Rxb1 Rxb1+ 35.Kh2 Rc1 36.Ne3 with a healthy extra passed pawn in the endgame. Or, he could have tried 29…Rb8 30.Ra6 Rb7 31.Re3 b1=Q+ (31…Bb5 32.Rxc3 b1=Q+ 33.Nxb1 Bxa6 34.Bxa6 Rxb1+ 35.Kh2 Ke7 36.Rxc7+ Kd6 37.Rxg7 Ra8 38.Bb7 Rb8 39.Bc6 Black is up the exchange but he failed to eradicate the isolani. So a win in this position will be difficult for either player.) 32.Nxb1 Rxb1+ 33.Kh2 Rc1 34.Rxa7 Nd1 35.Re2 Rxc4 36.Ra8+ Kf7 37.Rxh8 Nc3 38.Rd2 h6 39.d6 cxd6 40.Rxd6 Ne4 reaching a position where Black is ahead the exchange but, more importantly, time trouble would no longer be a factor in trying to maneuver for a win.

30.Re7

30.Rc6 b1=Q (30…Bg6 31.Rxc7 a5 32.d6=) 31.Nxb1 Nxb1 32.Ba2 Nxa3 33.Rc3 Nb5 34.Rxc2=

30…b1=Q?

Black must take the isolani off the board here. 30…Nxd5! 31.Bxd5 Rxd5 32.Re8+ (32.Nb1 Rd1) 32…Kf7 33.Rxh8 Rxd2 34.Rb8 Bd3 35.Kh2 c5 36.Kg3 c4 37.Kf3 c3 38.Ke3 Re2+ 39.Rxe2 Bxe2 40.Kxe2 c2 41.Rxb2 c1=Q 42.Rb7+ Kg6 and Black’s queen should outdual White’s rook. If White captures the a7 pawn he will be vulnerable to double attacks from the queen because the king has no place to hide. Especially bad would be 43.Rxa7 Qc2+ 44.Kf1? Qd1 mate.

31.Nxb1 Bxb1 32.d6!

The pawn finally advances a square and now White is winning. He needs to beat the clock to move 40 (5 minutes vs. 1 minute for Black). 32.Rxc7? is a blunder after 32…Bg6 33.Rxa7 Bf7. For example, 34.Ree7 Bg8 35.Rxg7 Nxd5 36.Rgb7 Rc8 37.Bxd5 Bxd5 38.Rd7 Ra8 39.Rxa8+ Bax8 40.Rd8+ Kg7 41.Rxh8 Kxh8 42.Kf1 Bc6 43.g4 Kg7 44.f4 h5 and it is unlikely that White can hold a draw.

32…Ba2

32…Ba4 also loses to 33.Rf7+ Ke8 34.dxc7. On 32…Bg6 White wins with 33.dxc7.

33.Rf7+ Kg8 34.Rd7+ Bxc4 35.Rd8+ Kf7 36.Re7+ Kg6 37.dxc7 Nd5

37…Ba6 38.Rxh8 is hopeless.

38.c8=Q Nxe7 39.Qg4+ Kh6 40.Rxh8 1-0

White made time control and Black resigned.

As I stated earlier, I was pleased with this game when it was played. After studying the tactics in detail, I have enjoyed it even more all these years later. I hope you will enjoy it as well. If you really want to improve, it’s all about tactics, tactics and more tactics.
