   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 ...

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 ...

Bubo bubo: After 28.Qc7+, Black loses his queen: 28...Qe7 29.Rg7+ or 28...Ke8 29.Bb5+.
 
   May-14-18 F Beltz vs A Guerrero Rodriguez, 2008 (replies)
 
Bubo bubo: White, who is already up a piece, wins with 31.Rxg6+ Kxg6 32.Qf6+, and it's mate after either 32...Kh7 33.Rh3+ Kg8 34.Rh8# or 32...Kh5 33.Rh3+ Kg4 35.Rh4#.

Bubo bubo: L’Année dernière à Marienbad
 
   Apr-09-18 O Ladva vs B Assaubayeva, 2017 (replies)
 
Bubo bubo: White exploits the pin on the long diagonal with 37.Bxf7+. Black cannot afford to capture with the rook (37...Rxf7 38.Rd8+ Rf8 39.R/Qxf8#), hence he has to give his queen by playing 37...Nxf7. A bit unusual for Monday, since White's win after 38.Qxb2 is not completely trivial.
 
   Mar-13-18 O Korneev vs Aronian, 1996 (replies)
 
Bubo bubo: White turns the double rook ending into an elementary win of two advanced passed pawns against a rook: 52.Rxh4+ Rxh4 53.Rxh4+ Kxh4 54.c6. Since his king is offside and the white king is close to the pawns, Black won't even reach the notorious Q vs R ending.
