   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#

Bubo bubo: Sad news again :( R.I.P. Daniel Freeman, and thank you for!
   May-31-18 E Hansen vs J Xiong, 2017 (replies)
Bubo bubo: The first move seems to be clear: the knight on d5 is attacked four times, but defendes only thrice. Hence 38.Rxd5, setting up a discovered attack against the black queen. A) Black has to recapture, since otherwise White wins another piece thanks to that discovered attack, for a ...
   May-30-18 A Heimann vs B Stillger, 2017 (replies)
Bubo bubo: White skewers the unguarded rook and the bishop with 25.Re4. Retreating the rook loses the bishop, and so does 25...Rcd8 26.Rxc4 (x-ray motif). Therefore Black has to capture, but after 25...Rxe4 26.Nxe4 the double threat of Rxc4 and Nd6+ wins at least the exchange.
   May-29-18 W Jacobusse vs S Potter, 2008
Bubo bubo: As yesterday, mate-in-3: 26.Rxh7+ Kxh7 27.Qh4+ Kg7 28.Qh6#
   May-28-18 M Elgohary vs K Elfelo, 2008 (replies)
Bubo bubo: Mate-in-3: 22.Rxh6 gxh6 (22...Kg8 23.Rh8#) 23.Qxh6 Kg8 24.Qh7#
   May-16-18 K Rathnakaran vs K Arjun, 2017 (replies)
Bubo bubo: White has a strong battery on the f-file supported by the bishop, but at the moment the invasion squares f7 and f8 are sufficiently defended. Hence he needs an additional attacker, and this can only be the e-pawn: 31.e6!, threatening 32.Qf7+ Qxf7 (32...Kh8 33.Bg7#) 33.exf7+ Black ...
