075. Testing the Theory


White: Dlanor - all-play-all tournament, ChessWorld.net, 2021

Well, my book is finally out and you can go and buy it... wherever, supposing you haven't already done so. I'd suggest not wasting any time anyway because, as I write in the Introduction: “Stockfish 17 may refute the whole lot in five minutes”. And we're currently up to Stockfish 14.1.

Meanwhile, I'm still testing the theory in my own games, and to considerable depth. For example, in the main line of E22 in Chapter Ten (Jaenisch 4 d3), which follows analysis by GM Dariusz Swiercz (to 27 Bf4), I've since had the chance to test Stockfish's riposte
27...g5!
as far as 28 Be5 Qxc2 29 Qe3 Qc6 30 Rd1 Rfe8 31 Qd4 Re6 (given by me in a bracket), and supported my comment “that Black can, if necessary, await a convenient moment to take on d6 and reach a drawable endgame”. In the game below we liquidated further to rook + pawn vs. rook and agreed a draw.

GM Keith Arkell (or someone) would want me to prove it over the board, I'm sure. To which end, at the end, something like 46...Rg8 47 Kh3 (or 47 f4 Kc5 48 Rd1 Rg4) 47...Rh8+ 48 Kg3 Rg8+ 49 Kf2 Rh8 50 Ke3 (or 50 f4 Rh3) 50...Re8+ 51 Re4 Ra8, intending ...Kd6, should do the trick.

Which also supports my comment here in an earlier post: “If you want to defend the Jaenisch as Black, study the endgame!

  1. Further adding to theory, Vishnuduta-tsmenace, all-play-all tournament, ChessWorld.net 2022, saw 25 e5!? Qa5 26 Rd1 Qxb5 27 Be3 d4 (it's worth returning a pawn to get the rooks off) 28 Rxd4 (not 28 Bxd4?! Qe2) 28...Rxd4 29 Bxd4 g6 30 c3 Qa5 31 Qh4 Qxa3 32 Qxh7 Qc1+ 33 Kh2 Qf4+ 34 g3 Qf7 35 Qxf7 Rxf7 (this endgame is drawn) 36 g4 Kb8 37 Kg3 a5 38 f4 Kc7 39 h4 Rf8 40 h5 gxh5 41 gxh5 Kd7 42 h6 Ke6 43 Kf3 a4 44 Ke4 b6 45 h7 Rh8 46 f5+ Ke7 47 Bxb6 Rxh7 48 Bc5+ Ke8 49 e6 Rh4+ 50 Kd5 Rf4 51 Ke5 Rc4 52 Bd6 Rxc3 53 f6 ½-½.
