|Nov-19-15|| ||paavoh: On the easy side for Thursday?!|
|Nov-19-15|| ||saturn2: Rd8 and 1-0|
|Nov-19-15|| ||starry2013: Initially I looked at the bishop check as it's most forcing, but it doesn't work.|
Then I looked at Rd8, black can't stop the inevitable checkmate, the only choice is whether it's the rook or the bishop that finishes things off.
|Nov-19-15|| ||CHESSTTCAMPS: White, down two pawns in an opposite colored bishop ending, has the black king trapped on the edge in the line of fire of the light squared bishop. This is one of those problems where you see the solution immediately or you suffer from Amaurosis scacchistica. The latter struck me today as I searched for a clever way to reinforce the attack on e6 or redeploy the rook. After switching to a different task for a while and coming back, it finally hit me: 75.Rd8! and undoubtedly the different variations of the quick mate have been laid out by numerous kibitzers already. Oh well, even Kramnik overlooked a mate-in-one.|
|Nov-19-15|| ||Fusilli: <paavoh: On the easy side for Thursday?!>|
|Nov-19-15|| ||dfcx: A simple deflection. Black's rook is guarding the pawn preventing Bxe6 mate.
75.Rd8 and black is being mated.
75...Bxg7 76. Rxe8+ Bf8 77.Bxe6+ Kh8 78.Rxf8#
75...c2 76.Bxe6+ Rxe6 77.Rxf8#
|Nov-19-15|| ||KabutoKoji: hello Tuesday?|
|Nov-19-15|| ||paulalbert: I am four for four this week because I have actually been able to spend time on calculating variations where there seems to be more than one plausible candidate move. I assumed correctly that probably one of today's variations involved letting Black's c pawn queen when it had no relevance because White was a forcing tempo ahead.|
Let's see what Friday brings.
|Nov-19-15|| ||Once: <dfcx: ...
75...c2 76.Bxe6+ Rxe6 77.Rxf8#>
Unfortunately, 76...Rxe6+ is a check so white doesn't have time for 77. Rxf8#.
|Nov-19-15|| ||catlover: Is it just me, or does this look like a composed problem? I know this is a real game, but the POTD somehow reminds me of some of the composed problems I've seen.|
|Nov-19-15|| ||yadasampati: Much too simple for a Thursday|
|Nov-19-15|| ||Jimfromprovidence: Here is a side puzzle.
White missed a forced mate beginning with move 70.

|Nov-19-15|| ||BOSTER: < paavoh: On the easy side for Thursday?!>.
Or when the player forgot Tarrasch rule that rooks should be placed behind passed pawns.
In the pos.black to play 54...

Black'd play Bd4 and Rf2+, and move the rook on "g" file.
|Nov-19-15|| ||YouRang: Well, the first thing I saw was the rather obvious try: 75.gxf8Q+ Rxf8 76.Kf6, and I went to the trouble to satisfy myself the white wins easily.|
I sensed that this wasn't the most elegant solution, but feeling lazy, I settled.
|Nov-19-15|| ||consul: <FSR> I've missed it, even knowing it was a puzzle. :-(|
|Nov-19-15|| ||TheaN: <Jimfromprovidence> interesting alternative, a striking difference based on the opposite colored bishops. In fact, it's white's only other move that keeps the advantage. |
For what it matters, Rd7 is a forced mate too, yet 22 instead of 6 :).
|Nov-19-15|| ||gawain: I'm having a bad week.
I thought I was clever for seeing 74 Rf7 with the threat of 75 Rxf8+ Rxf8 76 Bxe6+ Rf7 77 Bxf7# But I overlooked the various good replies for Black, such as 74 ...Bxg7 or even 74 ...Ba3.

|Nov-19-15|| ||stacase: White is lucky that Black's Queening Pawn wouldn't say check upon promotion.|
Who says there's no such thing as luck in Chess?
|Nov-19-15|| ||Pinkerton: My solution is a win eventually. Completely missed Re8. A stunner.|
|Nov-19-15|| ||Jimfromprovidence: <TheaN> <interesting alternative, a striking difference based on the opposite colored bishops. In fact, it's white's only other move that keeps the advantage.> |
Yes, white wins much sooner with 70 Re7!

White still has the same threat as the the text of 71 Kg6 seeing 72 Rd8# (except now its 72 Re8#).
The difference is the new threat of Rxe6 followed by Re8+ seeing Bd5#. Black cannot stop both threats and prevent mate.
One example is 70 Re7 Rc8 71 Kg6 c2 72 Rxe6 c1Q 73 Re8+ Rxe8 74 Bd5+ with mate next move.

|Nov-19-15|| ||dark.horse: Good one.
I thought it was one of those trick puzzles that was suppose to end in a draw. Those black pawns scared me.
|Nov-20-15|| ||Moszkowski012273: That whole 64.c4... line is flawed in the first place. 67...Kg8 and the best white has is a draw.|
|Nov-20-15|| ||kevin86: Syntax is important here: If the 75th move is bishop takes, black's reply will be a check!|
