Jun-19-17		lost in space: Had also thoughts about 16. Rg7 but Rf8 is so much simpler - fitting better my brain-status

Jun-19-17		agb2002: White has a pawn for a bishop. Black threatens Qxh5. The queen should be on f7 instead of the rook. Therefore, 16.Rf8+ and 17.Qf7#.

Jun-19-17		FSR: Good point, everyone.

Jun-19-17		Once: Fritzie confirms that 16. Rg7+ is mate in 4 while 16. Rf8+ is mate in 2. One point to watch is 16. Rg7+ Qxg7 17. e7+ Nxc4 click for larger view Now the temptation is to magic a second queen onto the board with 18. e8=Q+. Like cheesecake, who can resist a second piece of queen? Except in this instance we ought to think about our waistlines. The instant coronation would be met by 18...Bf8 and black has a lot of pieces to compensate for white's extra queen. The win from this position (which others have already mentioned) is 18. Qe8+ Qf8 19.Qxf8# click for larger view Good little puzzle.

Jun-19-17		stacase: White's Queen needs to occupy f7 instead of the Rook. Hmmm, how to move the Rook and not lose tempo? 16. Rf8+ does the job nicely.

Jun-19-17		saturn2: Rf8 clears the f7 square with tempo

Jun-19-17		morfishine: <16.Rf8+> and mate next move *****

Jun-19-17		saturn2: If one wants to complicate things he can try 16 e7 If 16..Qc1+ 17 Rf1+ winning the queen. If 16..QxQh5 then 17 e8D+ mate soon If 16..Bd7 17 Rg5 wins the queen If 16..NxB 17 Rf8 like in the game

Jun-19-17		SpamIAm: Arnhem/Amsterdam, eh? A Philidor Too Far.

Jun-19-17		WorstPlayerEver: Oh, thought I blundered with 16. e7

Jun-19-17		5hrsolver: 10..g6 maybe black can try to castle queenside.

Jun-19-17		whiteshark: <16.Rf8+!> and that's it.

Jun-19-17		steinitzfan: This is hard Monday. A short simple solution but a lot of blind alleys.

Jun-19-17		benveniste: I initially found ♖g7+, which is mate in 3. But I figured that was too hard for Monday and eventually got it right.

Jun-19-17		gawain: Whichever of his three moves Black tries, White mates with 17 Qf7. Nice.

Jun-19-17		PJs Studio: I first saw Rf8 is mate in one, so I looked no further. I've found that looking for clearance FIRST, then forks and sacs, is usually best. Clearance can be assed through searching the board quickly - before going on to other tactics. After exhausting all of your tactical possibilities, positional considerations (which, of course, can be very laborious) come to the forefront.

Jun-19-17		mqhelisi: missed the Monday of all days went for the grinding Rg7+ mate after a hussle

Jun-19-17		PJs Studio: It's games like this that scare me from playing 1...e5!

Jun-19-17		drollere: <If one wants to complicate things he can try 16 e7> i also went for e7, as nothing seems to win for black and it's just better mayhem.

Jun-19-17		Iwer Sonsch: 16.Rg8+ Qxg8 (Kxg8 Qf7#) 17.e7+ Qf7 18.Qxf7#. Pretty brilliant for a Monday.

Jun-19-17		Iwer Sonsch: Missed a Monday (17...Nxc4). Still working and more beautiful though.

Jun-19-17		OhioChessFan: Kind of a tough Monday. I apparently am the only person who had a bit of chess blindness in that I was looking for Qe8+ as a followup to Rf8+. That is, my first thought was "If I could only get the Queen past that Rook, the Queen would mate on e8." It took a little longer than it should have to see that the real clearance was the Rook's original square to be inhabited by the Queen.

Jun-19-17		dumbgai: Silly me, I went for 16. Rg7+ which is inferior. It wins but makes white's task harder than it needs to be.

Jun-20-17		kevin86: Rook sac and queen mate next!
