Black: Jarolim - Unrated game, ChessWorld.net, 2004
If you've ever clicked on my profile, you'll have read the words: “genderqueer femme”. In short, that means my gender is “queer” in some unspecified way, qualified by the placement “femme” within the butch/femme spectrum. To explain that in long would mean a conversation and likely some more reading on your part.
And what does it have to do with chess anyway? Not very much. Neither gender, nor sex, is a serious indicator of inherent chess ability. (Nuts to Nigel Short.)
But there is one instance where chess and non-normative gender collide, and that's the Transvestite Attack. This was an invention of US player Jack Young, and involves the moves 1 e3, 2 Ke2, 3 Qe1, 4 Kd1, whereupon White's king and queen are on each other's squares, wearing each other's clothes, as it were.
For instance: 1 e3 e5 2 Ke2 d5 3 Qe1 Bc5 4 Kd1 f5 5 Nf3 e4 6 Ng1 Nf6 7 b3 0-0 8 Bb2 c6 9 Ne2 Nbd7 10 f3 Qe7 11 Qh4 Bd6 12 h3 Be5 13 Nbc3 a6 14 f4 Bd6 15 g4 Nc5 16 gxf5 Bxf5 17 Nd4 Qd7 18 Nxf5 Qxf5 19 Be2 Ne6 20 Bg4 Nxg4 21 hxg4 1-0 was J.Young-D.Sarkisiam, USA 1988. This appeared in Rainer Schlenker's offbeat openings magazine Rand Springer, issue #46 (1989).
Obviously White's set-up has no merit whatsoever. On completing the manoeuvre White is clearly worse, having wasted three tempi with the royalty, and is now unable to castle. But it seems Jack's thing was to see what he could get away with. Hence a few characteristically silly moves, given a name for posterity, and start the game from there. It helped that he was (is?) quite a decent player, rated USCF 2261 in 1988.
I've never tried 1 e3 e5 2 Ke2 myself. Even if I had, it wouldn't be blog-relevant, and trying a similar thing in an Open Game (e.g. 1 e4 e5 2 Qe2 Nc6 3 Kd1 Nf6 4 Qe1) would probably lose by force. However, there is one opening in which it can arise naturally: 1 e4 e5 2 f4 exf4 3 Nc3 (the Mason Gambit) and now 3...Qh4+ 4 Ke2.
In this sequence the white king has to go to e2, and is going to have to move again; challenging queens with Qe1 is then often useful for White; and retreating the king to d1 frees the light-squared bishop. This situation has occurred several times in my praxis. Each time, Qe1 and Kd1 were actually correct and led to an advantage for me (even if I didn't always follow them up correctly). The game below is one example. (I've included another, more recent one in the notes.)
Here 9 Kd1 has uncovered an attack on the a6-knight, which is defending the c7-pawn. A further threat is 10 d4, regaining the f4-pawn with advantage. Black has no satisfactory way to solve these problems. Captain Transvestite strikes again!

White: Ares777 - all-play-all tournament, ChessWorld.net, 2018
An opening sacrifice (8...0-0!?) – first seen in G.Sanakoev-J.Boey, 10th World Correspondence Championship 1978 – gave me good play for a pawn in the early middlegame, which developed successively into a strong initiative, a material advantage, and (after 47...h4!) a winning endgame with queen vs. rook and pawn.
The Shredder endgame database gives this as mate in 50. I spent a long time trying to understand why this is so, searching MegaBase for similar positions, and getting my endgame books down from the shelf.
GM Karsten Müller & IM Frank Lamprecht (Fundamental Chess Endings, Gambit 2001) write: “If the pawn is on its original square or if it is a knight's pawn the position is drawn, as long as the attacking king is cut off and can't get behind the pawn.”
GM Efstratios Grivas (Practical Endgame Play, Everyman 2008) writes more expansively:
“(...) provided that the defending king and rook are close to the pawn and that the opponent's king cannot attack from behind. The basic rules are:
1. With a central (c, d, e and f) pawn, it's a draw if the pawn is on the second, sixth or seventh ranks, but otherwise the queen wins.
2. With a b- or g-pawn, it's always a draw.
3. With a rook pawn, it's a draw if the pawn is on the third or seventh rank, but otherwise the queen wins.”
And yet Shredder says I'm winning. Well, the authors are not wrong in what they say about the g-pawn, since they give the necessary proviso: if the attacking king cannot get behind the pawn. But it certainly doesn't look as if it can from the diagram.
The crucial stages are as follows:
- First of all, 48...Qf2+! 49 Kh3 Qg1 threatens mate, so the rook has to drive the black king out and across the f-file (50 Rg4+ Kf5 51 Rf4+ Ke5).
- Then (after 52 Kh4 Qh2+ 53 Kg4) the passing move 53...Qh1! creates a sort of zugzwang, in that White has to weaken his fortress slightly. In particular, if he moves the rook on the f-file (which offers the longest defence), either immediately or after 54 Kg5 Qh3 (seeing that 55 g4? Qe3 wins at once), the black king will advance up the board.
- Then the queen returns down the board to hassle the white king from in front. Eventually, the rook has to give up control of the f-file, allowing the black king across and behind the pawn.
- Black can then win the pawn, and then win with queen vs. rook.
The first three points above are exemplified in a superb endgame by the Czech master Emil Richter. From the position after 53...Qh1!, play continued 54 Rf2 Ke4 55 Re2+ Kd3 56 Rf2 Ke3 57 Rf4 Qb7 58 Kg5 Qg7+ 59 Kh4 Qh6+ 60 Kg4 Ke2 61 Rf5 Qg6+ 62 Kf4 Kf2 63 g4 Qd6+ 64 Kg5+ Kg3 65 Kh5 Qd7 66 Kg5? (making it easy) 66...Qg7+ and "White" resigned. I've put White in inverted commas there, because the moves were actually 76 Qh8! through to 89 Qg2+ and 1-0 Em.Richter-G.Stoltz, Karlovy Vary 1948, since the colours were reversed.
My game followed V.Burmakin-V.Lazarev, Werfen 1993, with 55...Qc1+! being a critical improvement. Black has to prevent the g-pawn from advancing freely. In the final position (where I claimed the game on time), White can in fact play 57 g4, but then the annoying pin on the rook means he has to waste moves with his king, allowing Black to get round behind; e.g. 57...Qd2 58 Kf5 Ke3 59 Kg5 Qd8+ 60 Rf6 Ke4 61 Kg6 Qg8+ 62 Kh5 Qh7+ 63 Kg5 Qg7+ 64 Rg6 Qe5+ 65 Kh6 Qe7 66 g5 Kf5 67 Rg7 Qf8 68 Kh7 Qa8 69 Rg6 Qh1+ 70 Kg7 Qh2 etc.
Incidentally, the Lomonosov tablebases show that the win can be considerably shortened by refusing the a-pawn on move 39. Apparently, 39...Qxa4 (its sixth choice) is mate in 59, whereas 39...Qe3! and 39...Qf7! are both mate in 37. I rejected those for two reasons:
1. White could have forced the game position by playing 39 Rf2 first.
2. Why on earth would Black refuse the pawn? I'd never refuse the pawn over the board.
Except that now I might. The a-pawn is not going anywhere. Yes, White can defend it with the rook, forcing the queen to blockade it for the moment. But when the black h-pawn comes up the board, White will then have to take it with the g-pawn, giving him two rook's pawns – until one of them drops off, after which he'll only have a rook's pawn, and on an unfavourable square, making the win that much more straightforward.
Damn, I love endgames.
