I'm a semi-retired mathematician, born in Cardiff and living in Southampton UK. I played a lot as a student, coming second in the 1967 Welsh Senior and British Junior (under-21) Championships. After a long career-and-family break from chess I started playing again in 2011, mainly in the local Southampton league, but occasionally in international team tournaments on lower boards for England Seniors. My FIDE rating is 1926.

Brenin: 35 ... Rxg1+ 36 Kxg1 Ne2+ 37 Kh1 (37 Kf1 Bh3+ 38 Ng2 Bxg2+ 39 Ke1 Bxe3 40 fxe3 Nxc3, followed by Ne4 and advance of the f-pawn) Bxe3 38 fxe3 Be4 as in the game.
   Sep-21-23 P Johner vs F D Rosebault, 1910 (replies)
Brenin: 22 Re5!, threatening 23 Bxf8+ gxh5 24 Rxh5 mate, and if 22 ... gxh5 then 23 Rg4 and 24 Bg7 mate.
   Sep-20-23 A Antunes vs A Bejaoui, 1997 (replies)
Brenin: I saw 19 Nc6, and expected 19 ... bxc6 20 Rxb8 Bxc3 21 Qxc3 with a moderate advantage to White, but not a clear win. Black's 19 ... Bxc3 20 Nxe7+ Kg7 21 Qxc3+ f6 22 Qxc5 simply loses a piece. With the Black Q on b4, why didn't White play 18 Nxg6? If 18 ... fxg6 then 19 Bxg7, ...
   Sep-20-23 J Mason vs F Perrin, 1873 (replies)
Brenin: I chose 20 Rxd5+ Kxd5 21 Qd3+ Ke6 22 Qd7 mate, overlooking 21 ... Bd4+ 22 cxd4, which still wins for White, e.g. 22 ... c4 23 Rb5+ Ke6 24 Qe4+ and mate in a few moves.
   Sep-19-23 A Needleman vs A Cordero, 2003 (replies)
Brenin: OTB I'd go for the quick, clean kill 44 Rd8+, 45 Bg5+ and 46 Qxe4: Black's moves are forced and he immediately loses his most active piece. In <mel gibson>'s Stockfish line 44 Bg5 Qa8 45 Qd4 Be7 46 Bxe7 Rxh6 Black is threatening mate on h1, forcing 47 Bh4; I'd need to be very ...
   Sep-19-23 H Caro vs Lasker, 1890 (replies)
Brenin: "I am dead, Horatio. Wretched Queen adieu." 14 ... Kf6 15 Nd7+ seals her fate.
   Sep-18-23 A Kovalev vs A Ushenina, 2003 (replies)
Brenin: 14 ,,, Bb7 looks like a natural developing move, but it leaves the Black K fatally weakened, and vulnerable to 15 Rxe6+, which nets an immediate 3P and a crushing attack as compensation for the R. Black needed to be bolder with 14 ... g4, e.g. 15 Qxh6 gxf3 16 Rxe6+ fxe6 17 Qxe6+ Be7 ...
   Sep-18-23 Moreau vs Albin, 1903 (replies)
Brenin: <Teyss>: Namibia drew 0-0 with Canada in 2019, when the match was cancelled due to a typhoon. Colonel Moreau wasn't so fortunate, though he fared rather better as a military officer and as a mathematician.
   Sep-18-23 L De Veauce vs J N Sugden, 1971 (replies)
Brenin: Black's 42 ... Qxe4 was a blunder, leading to a quick (and easily spotted) mate. He could have avoided this with 42 ... Qd1+ 43 Kf2 Qd2+ 44 Qxd2 Nxe4+ 45 Ke3 Nxd2, with almost equal material, but then today's second choice move 46 Ng6+ restores White's significant material advantage.
   Sep-17-23 M Ragger vs M Leon Hoyos, 2008 (replies)
Brenin: <K.A.B>: After 30 Bxd4 Qxd4 31 Qxe2 Qd8 I think that 32 Qc2, aiming at g6, is stronger than Qc4, e.g. 32 ... Qf6 33 Qc7 Kg8 34 Qh7+ Kf8 35 Rc6, and the Black Q cannot guard all the mating squares.
