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: Nice pun, nice finish: 35 ... Kxg7+ 36 Ne6+ Kh6 (or h7 or h8) 37 Qh4#. The final attack would make a good POTD, depending on where one starts.

Brenin: White is the exchange and 2P (passed, connected) ahead, but has a little problem from the Black R on d4. Solution: liquidate it with 26 Rxg7+ forcing Kxg7 (else mate on g8) 27 Bxe5+ Kh7 (better to keep Bs on, rather than Bf6) 28 Qxd4, and after 28 ... Qxh3 White has gained another P ...
   May-17-21 D J Ledger vs P K Wells, 2001 (replies)
Brenin: One second to find a good move (31 ... Rh1+), and perhaps another two seconds to follow Lasker's advice and look for a better one, rejecting 31 ... Qh3+ 32 Kxh3 Rh1+ as there is no P on h5 to prevent 33 Kg4.
   May-16-21 I Novikov vs G Shahade, 2001 (replies)
Brenin: <goodevans>: In your line, Black also has 21 ... Qf8, but this loses to 22 Nf6+, e.g. 22 ... gxf6 23 Qxf6 with mate on h8, or 22 ... Kh8 23 Qe4.
   May-16-21 B Socko vs Krasenkow, 2000 (replies)
Brenin: Black needs the quiet but forceful move Rf8 to reinforce the attack, but 32 ... Rg6+ must come first, otherwise White repairs the crumbling wall with 33 Nf1 and 34 Ng3, blocking the g-file and attacking the P on e4. Clearly the h-pawn will need to be advanced at some stage, to free ...
   May-15-21 Chernin vs P Bono, 2005 (replies)
Brenin: <nisharaj31>, <alussinan>: There's nothing wrong with 33 ... Nxe7: after this capture, Black is a piece up, and White has very little compensation. I see three possible explanations for White playing 33 Rxe7 and Black neglecting to take this gift. (a) This was a desperate
   May-15-21 Csom vs Kindermann, 1986 (replies)
Brenin: Yet another POTD in which the first few moves are obvious, but the follow-up is more delicate. OTB I'd consider 3P for the N (even after 24 ... Kg7 the third will surely fall), the exposed Black K, the relative absence and immobility of his lieutenants, and (if all else fails) the ...
   May-14-21 G P Gruen vs D King, 1987 (replies)
Brenin: 30 Be7 was careless; instead, 30 Re3 would have nullified the exchange sacrifice played, since with 32 ... Qxf3 prevented the White K is now safe on h1.
   May-13-21 A Deviatkin vs J P Wallace, 2012 (replies)
Brenin: Nice mixture of strategy and tactics from White. I imagine that by now he is getting a little tired of puns based on his name, whether in English or Russian.
   May-13-21 R Svane vs V S Gujrathi, 2018 (replies)
Brenin: The first few moves, 26 ... Rxe2+ 27 Kxe2 (otherwise White is B+P down and the attack continues) Bd3+ (cutting White's Q off from defending the K) are easy to see. One simply needs to verify that the White K has no route to safety.
