@floreatdunum, agreed. I suspect many may play QxRe4 instead without pausing to think about it.

Karma must exist! And I have done some horrible things in my many lives. Why else should I fail this problem over and over again? So simple, so painful.

Agree with tomo. Solution too short.

Qe5+ doesn't win the rook...
2017-08-20 18:04:24floreatdunum1707Problem p39838
I would suggest that this is more akin the Opera mate, rook on back rank supported by a bishop.
2017-08-20 00:10:03chessisajedrez1746Problem p30263
It makes SO MUCH sense, but it takes me so long to see it. Like defensive problems.
2017-08-19 23:37:22chessisajedrez1746Problem p39838
Similar to the Reti mate noted by @floreatdunum in problem p16244 ( ?Pos=28842)
2017-08-19 23:00:04chessisajedrez1746Problem p16244
Wow, @floreatdunum's Reti-Tartakover is only 11 moves long!? Anyway, there is an even more similar mate in another CTS problem. Everybody praises it.
2017-08-19 18:51:23floreatdunum1707Problem p16244

One should point out that in the game reference kindly given by slowness2014, Black did not play the obvious blunder 15... Nf5, but 15... Bg7. The game ended in a draw by perpetual: 16. Qf7 Bd5 17. Qe7 Qf3 18. Kf1 Qg2 19. Ke2 Bf3 20. Kd2 Qf2 21. Re2 Bh6 22

if you know, how this mechanics work, then its very very easy to find the solution. To describe the whole idea behind the puzzle is much more complicated. therefore allways look for a mate ! regards.
2017-08-19 13:48:09Bisonratte1549Problem p43341
@ SaintMark, ive some sheets of the basic mating patterns (maybe google helps). If you look how bl establishes the mate (just watch the last position), then you may detect, there are initial parts in this puzzle.

I played Bd4 aswell
2017-08-17 14:41:13Bisonratte1549Problem p18342
poisoned pawn, defending move: White has no time for Nxe4, because then blacks attack gets too strong (Rf6/g6 with infiltration Bh4 on e1, and wQ has no squares).

Having just had p53017, this was a piece of cake.
2017-08-16 04:20:29Freeze1511Problem p19630
I touched my queen for Qh3, but then thought I saw a dual coming. I should have paused another moment to see why, but I figured either way would work. Of course, this was not a dual, as explained above.
2017-08-15 21:58:15chessisajedrez1746Problem p17088
@SaintMark, don't overlook you just got a free pawn too. (Taking the R leads to a mate combination)
2017-08-15 16:29:17SaintMark939Problem p17088
So what happens if the pawn doesn't take the rook? Or is this just about saving the knight?
