   Nov-14-18 D Perrett vs I Efimov, 2008 (replies)
Bubo bubo: Black forces mate with 26...Re2+: A) 27.Nxe2 Qxe2+ 28.Kg/h3 Qf3+ 29.Kh4 Qg4# or 28.Kg1 Nf3# B) 27.Kh3 Qf3, and White cannot prevent 28...Qg4#.
   Nov-13-18 K O'Brien vs D Salter, 2008
Bubo bubo: Mate-in-4: 20...Qxh2+ 21.Kxh2 Nxg3+ 22.Qh4/h7 RxQ+ 23.Kg1 Rh1#
   Nov-12-18 M de Jong vs V Akotchik, 2008 (replies)
Bubo bubo: 41.Rxe8+ Qxe8 42.e7+ Qf7 43.dxe5 and mate next move, but the simple 41.dxe5 also works (41...Qb7+ 42.Kg1 Qxc8 43.e7+ and mate next move), and so does the modest 41.Qxg6+ Kf8 42.Rxe8+ Qxe8 43.Qxe8+ Kxe8 44.dxe5.

Bubo bubo: Black wins a rook (and a pawn) with 29...Qxf3+: A) If White recaptures, he moves his queen into a pin, leaving the rook unguarded. Hence 30... Rxe2+ wins a rook - and subsequently the queen, because it shoos away the king: 31.K~ Bxf3. B) Fleeing with the king does not help either:

Bubo bubo: Hooray, it's October 24, and we have a very reputable <POTD> at last! RIP Georg Salwe - I wonder how good you could have been if you had learnt to play chess earlier in your life.
   Oct-24-18 Prince Andrey Dadian of Mingrelia
Bubo bubo: Hooray, it's October 24, and the most infamous villain in chess history is not <POTD> again - I consider this a good omen!
   Sep-12-18 W So vs Carlsen, 2016 (replies)
Bubo bubo: Black wins a rook with 28...Qxd1+ 29.Bxd1 (29.Kg2 Bf1+ loses the queen) Re1+ 30.Kg2 Bf1+ 31.Kf3 (31.K~1 Bh3#) Ne5+ and 32...Nxd7.
   Sep-11-18 Y Zherebukh vs Akobian, 2017 (replies)
Bubo bubo: The Rd1 must not leave the back rank, hence Black can fork that rook and the knight with 28...Rd2, winning a piece (29.Nf6+ Kf7).
   Sep-10-18 Michelet vs Kieseritzky, 1845 (replies)
Bubo bubo: I wonder whether the identity of the winner of this spectacular game will be unveiled some day. Probably not, but maybe there is hope after all: for a long time we did not know more about the loser of the famous <two queens lose against a bunch of minor pieces> game ( R ...
   Sep-10-18 R Safar vs I Agrest, 2008 (replies)
Bubo bubo: What a bummer: missed the more Monday-ish 3# featuring one of my favorite checkmate patterns: 26...Qxg2+ 27.Kxg2 Bxh3+ 28.Kh~ Bxf1#
