042. Days of Innocence


Black: C.S. Thomson - BPCTC, 1993-94

Once upon a time, when people used to play 1...e5 against me (which no one has done OTB for three years now), I got to utilize a lot of "unexpected" variations in the King's Gambit. One of these was the Rosentreter: 2...exf4 3 Nf3 g5 4 d4!?, intending 4...g4 5 Bxf4 gxf3 6 Qxf3 with practical chances (see here, for instance), based on the fact that Black has no pieces out at all.

Some players, perhaps surprised by 4 d4, would try to reach a standard set-up with 4...Bg7, intending ...h7-h6, ...d7-d6 and so forth. Only to be confronted by 5 h4 h6 6 hxg5 hxg5 7 Rxh8 Bxh8 8 g3! (Keres), after which they found themselves instead in a fringe line of Becker's Defence, not knowing what to do.



I used to do quite well with this line (8...g4 9 Nh2! is the main point), even against FIDE titled (or future titled) players, such as: Gregory Kaidanov, Mark Hebden, James Cobb, and Robert Eames. My opponent in the game below, Craig Thomson, has a title too (he's an FM – whether at the time or later, I'm not sure), though the Becker wasn't a surprise to him because he started it off with 3...h6. (In any case, the element of surprise tends to be more potent in rapid chess than postal chess.) All the same, he didn't manage to defend correctly, and I won – as I thought then – a nice game.

They feel like days of innocence now. Neither that game, nor any of the others mentioned, stands up to engine scrutiny – especially the one against Hebden, which exemplifies Tartakower's maxim: that the player who wins is the player who makes the next-to-last mistake; i.e. it didn't matter that Hebden blundered first (17...Qf5??), nor that several other moves by both sides were also blunders, because I blundered last (38 Bf4??) and therefore lost.

If there's a reason I stopped playing 5 h4 and 8 g3, I've forgotten what it was. Maybe there wasn't a reason. Today, Stockfish gives Black the edge, but not fatally so. Or as John Shaw put it in his book: “The King's Gambit – not quite as stupid as it looks.” On the other hand, on the few occasions in recent years I've gotten as far as 2...exf4 as White, I've only played 3 Nf3 twice. Coincidentally, the last of those was against Hebden again (in 2016), where he blundered first again, and won again. Some things never change.

018. All Rook Endgames are Drawn


Black: tripoduk - Chess.com, 2017

For five years now I've been playing an ongoing series of friendly games on Chess.com against someone under the name of “tripoduk”. I generally visit the site first thing in the morning, make a couple of quick moves, and go away again. As my opponent is much weaker than me, and as I don't play against anyone else on Chess.com, my win-to-loss ratio is very high indeed. In fact there have been no losses at all, and when I'd racked up a score of +89 =2 -0 (98.9%), the site administrators decided I must be cheating and banned me – albeit only temporarily. Once I'd explained the situation to their satisfaction (CC-SIM vs. relative novice), they let me back on under a new name and gave me a Diamond membership too as a titled player. Well, grand.

Since then we've played another 41 games, the score in which is currently +32 =9 -0 (89.0%) in my favour. Still no losses, but you'll notice that my percentage has decreased somewhat. My opponent is getting better. And in the game below, he should have had me.

Most of the games with me as White have been King's Gambits, and the following critical line of Becker's Defence has arisen several times: 1 e4 e5 2 f4 exf4 3 Nf3 h6 4 d4 g5 5 Nc3, followed by 6 g3. John Shaw's King's Gambit book (pp 171-6, 231) has been useful here, and up to 2016 I'd scored 8/8 as White: five wins after 5...d6 6 g3 Bg7 7 gxf4 g4 8 Rg1!; one each against 6...Nc6 and 6...g4; and one more after 5...Bg7 6 g3 fxg3 7 hxg3 d6 8 Be3.

In our most recent game, my opponent repeated the last of those variations – and much more strongly. After his 12th move I was struggling to find any compensation at all for the sacrificed pawn. I continued struggling to find any as the game progressed, and watched rather helplessly as my position declined from worse to bad to lost. In the diagram below, White is completely lost.



The logical plan for Black now is to trade the g-pawn for the white a-pawn, swap the bishops off in the process, and win the rook endgame with two extra pawns.

It's not entirely trivial: the direct 55...Bb2 56 Kxg5 Bxa3? etc leads to a draw (as in the game); but rather than take the a-pawn at once, the switchback 56...Be5! forces the white rook to give way (57 Rd7+ Ke6 58 Rd8? runs into 58...Bf6+), after which Black should win easily enough. Temporizing with 56 Kf5 doesn't help either, since 56...Bxa3 57 Bxa3 Rxa3 58 Kxg5 wins for Black, if only just (58...Ke7! 59 Rd4 Ra1 60 Rxd3 a3 61 Rd2 Rf1! 62 Ra2 Rf3 63 Kg4 Rb3 64 Kf4 Kd6 65 Ke4 Kc5 and so on); while 56 Bd2 Rxa3 57 Kxg5 (or 57 Bxg5 Rc3) 57...Be5! is equally hopeless for White.

The immediate 55...Be5! is good too; e.g. 56 Rd7+ Ke6 57 Rd8 Bb2, when White can't take on g5 and otherwise Black takes on a3 and wins again.

Instead, I was given a reprise: 55...Bc3? 56 Bxc3 Rxc3 57 Kxg5 Rxa3 58 Kf4 and this rook endgame is drawn since Black can make no progress; e.g. 58...Rb3 59 Ke3 a3 60 Kd2 Ke7 61 Ra6 and if the black king advances up the board it gets checked away from behind; or 58...Ra1 59 Rxd3 a3 60 Rd2! a2 61 Rf2 (safeguarding the white king from checks) and if the black king advances up the board to the third rank, it gets checked away from the side. This made me think of Tarrasch's maxim: “All rook endgames are drawn”. By which he meant that even quite favourable-looking rook endgames can be difficult to win, and sometimes they can't be won at all.

As it happens we've just started another game with the same line (up to 8 Be3 so far), so I'll have to find an improvement pretty soon. Hmmm.

200 Open Correspondence Games


Back in 1992, when I began my tenure as editor of the BCCA Magazine, Correspondence Chess, contributed copy was scarce, as it often was, before and since (nobody got paid). So, in order to fill a few more pages of my first issue (CC#117, January 1993), I wrote the following article:

_______________________________________________________________________

Three Open Games

If I had to pick one book from the 1992 crop of chess literature, it would be the re-publication of Grandmaster David Bronstein's 200 Open Games. If you are ever feeling fed up with chess – disillusioned by a horrible loss, perhaps – this book is a tonic guaranteed to restore your enthusiasm.

But the most unique feature of 200 Open Games is the manner in which Bronstein presents his games. Instead of conducting the usual wall-to-wall analysis, he introduces each one with a little story bringing to life some aspect of the game or of the chess world in general.

Of course, few writers can be as gifted or as entertaining as Bronstein, but his method has the advantage of allowing an author to include games that would not normally be considered for a selective collection; for example, the twelve-move draw, Bronstein-Ivkov, Vienna 1957.

It is this approach that I would like to exploit in presenting my own Three Open Games.

White: T.F. Deery - BCCA Major, 1988-89

The reader might consider the following game to be little more than the technical realization of an advantage. White misplayed the opening and lost a pawn without sufficient compensation. In postal chess, an error of this magnitude is usually decisive.

But what would you think if, instead of 27 Nc2, White had gone 27 Nb5 Rae8 28 Nc3 ...? The game could then have adorned the anthologies for years to come, given Black's spectacular sacrifice 28...Qxc3!!.



You will see that, despite having no less than four ways of winning the queen, White is lost no matter which one he chooses:
(i) 29 R1xc3 Re1+;
(ii) 29 R4xc3 Re2 (threatening 30...Bg2+) 30 Qxe2 Rxe2 31 Rg1 Bg2+ 32 Rxg2 Re1+;
(iii) 29 bxc3 Re2 30 Qxe2 (30 Rd4 Bg2+ and 31...Rxd2) 30...Rxe2 31 Rd4 Bxd4 32 cxd4 Re3 with a winning endgame;
(iv) 29 Qxc3 Re2 30 Rd4 R8e4 31 Bc4 Bxd4 32 Qxd4 Rxd4 33 Bxe2 Rxd5 again with a winning endgame; for example, 34 Rxc7 Rd2 35 Bf3 Rf2.





Black: K.W. McLaughlin - BCCA Premier, 1989-90

An entertaining variant of chess, other than those outlined by Malcolm Horne in CC#115, is the one known to me as ‘Scotch Chess’. The only difference in the rules from ordinary chess is that on capturing a piece or pawn, you must immediately replace it on the board – on any unoccupied square, subject to the restrictions that pawns cannot be placed on the 1st or 8th ranks and, obviously, you should not put yourself in check.

As neither player loses material, the main strategy of the game involves reducing the scope of the opposing army – usually by clustering enemy pawns towards one corner and putting pieces in behind them; e.g. black pawns at a6, a7, b6, b7, c6, c7 and bishop at b8 will form a close cage (for the queen) around a8. The extrication period can be used trying to checkmate the king.

It may have been familiarity with Scotch Chess that led me to a similar idea in the following game.

Consider the position after 11 Qd2. As compensation for White's lead in development and strong, mobile centre, Black has three extra, advancing kingside pawns. However, suppose White plays 12 Rxh4 and, after 12...Qxh4, 13 Bg5, forcing the queen down the h-file in front of the pawns, Black tries to drive away the bishop by ...f6 but White ignores the threat, allows ...fxg5, and instead manoeuvres a knight to f1, pushing the queen back to h4.

Look now at the diagram! Black's once-menacing pawns now merely encage their queen which, devoid of sensible squares, will take no further part in the game!



A rather fanciful idea, perhaps? No doubt the reader will find many flaws in it, but with a little help from Black, who knows? Unfortunately, Keith had other, more vigorous plans for his pawns and so carefully retreated his bishop out of their way with 11...Bf6.

As for the game itself, I have included it in my Three Open Games largely because I do not understand it and so cannot annotate it properly; but please do not be deterred from playing the game through to the end, since the final position of Black's rooks' pawns is quite unique.





Black: W.F. Lumley - BCCC Candidates, 1991-92

Ishlinsky, when asked “is it worthwhile putting so much effort into chess?”, replied “it is worthwhile because chess gives a man more than he puts into it.”

I should expand the context of this quote to ‘he/she’ and ‘man/woman’, but it can become tiresome to do so and makes for clumsy writing. There is much to be said for the adoption of Marge Piercy's personal pronoun ‘per’ in such cases.

But never mind that! The gist of Ishlinsky's statement is clear – and how much more so for correspondence chess players! The reader will know from per (!) own games how analysis can yield amazing variations when not fettered by over-the-board time limits. However, it may be possible to get too carried away.

The following game was almost one of my favourites. After achieving a sizeable plus from the opening, I was very pleased with my play, realizing this advantage in the rest of the game. Except that, at the end, I gave up my queen for a mate that was not there.

Look at the position after 24 Nb5.



I considered 24...Bg7 to be forced, as 24...fxg4 25 Rd8+ Qxd8 26 Rxd8 is mate. So I immersed myself in some pretty lines following 24...Bg7 25 Qg1!; e.g. 25...Qa5 26 Qxa7+! or 25...Qxf4+ 26 Kb1 b6 27 Nxa7! Kxa7 28 Ra5+ and wins. Consequently, I was not a little dismayed to receive by return of post the reply 24...fxg4!. Of course 25 Rd8+ Qc8! is not mate at all, so I had to resign.

Bitter self-recriminations followed and I gave up chess for nearly a week. I hardly need to point out to you that 24 Nxf5 wins quite easily for White.




_______________________________________________________________________

I was quite pleased with that, and still am, even if some footnotes are now warranted:
— In the first game, there's no actual need for 27...Qxc3!?, since 27...Bg4 (among other things) wins far more easily.
— In the second, the queen cage is pretty much impossible. White would have to play something like 12 Rxh4 Qxh4 13 Bg5 Qh2 14 Kf1 f6 15 Qe3 fxg5 16 Re1, be given several free moves (Re2, Ke1, Nb1, Nd2, Nf1), and has a losing position even so.
— In the third, I'd now offer the non-binary inclusive, singular “they” as a gender neutral pronoun; while in the game, 24 Nxf5 isn't the best move either: 24 Qg1! was correct, followed then by 25 Nb5 (even after 24...a6), when my variations actually work.

I have, I confess, occasionally thought about writing my own book: 200 Open Correspondence Games, based on my experiences at “remote chess” (Fernschach), by post (snail mail), by email, and (nowadays) on online servers. The issues with that idea are obvious: who would want to publish what is primarily a vanity project? And more pertinently: who would want to buy it?

But that's the great thing about blogs, isn't it. It doesn't cost anything to post things online, and if no one much (or at all) reads your posts, never mind, you've had fun writing them. So here it is, my new blog: 200 Open Games.

All will begin with the moves 1 e4 e5 – or transpositions thereto – the prerequisite for an Open Game. Bronstein arranged his book by openings: “The Queen's Attack”, “The Bishop's Attack”, “The QP Attack”, and so forth. I won't be doing that. Instead, I'll add tabs for opening names and ECO codes, C20 through C99 – within which I have some areas of special interest:

C23: Calabrese Counter-Gambit: 1 e4 e5 2 Bc4 f5.
C34: King's Gambit, Wagenbach Defence: 1 e4 e5 2 f4 exf4 3 Nf3 h5.
C57: Two Knights, Traxler Variation: 1 e4 e5 2 Nf3 Nc6 3 Bc4 Nf6 4 Ng5 Bc5.
C63: Ruy Lopez, Jaenisch Gambit: 1 e4 e5 2 Nf3 Nc6 3 Bb5 f5.

And the second one there in particular, since we (János and I) have been playing and analysing the Wagenbach for, what, 25 years now.

So I might as well start with one of those...
