| May-05-09 | | geeker: Finally got one! And the first variation I examined. ;-) |
|
May-05-09
 | | patzer2: For today's Tuesday puzzle, 20...Bxf2+! exploits the weakened back rank with a forcing double attack to decoy the White Queen and set up a quick mate. |
|

 | | OhioChessFan: I did as <Smothered Mate> did and tried d5 first. |
|
| May-05-09 | | YetAnotherAmateur: f2 looked like the obvious place to attack, so I started with
20. ... Bxf2+
21. Qxf2 (otherwise, drop the queen immediately)
From there, it was pretty clear that 21. ... Qxf2+ wouldn't cut it, so I started looking for alternatives, which led immediately to
21. ... Qa1+
22. Rb1 Qxb1+
either
23. Qe1 Qxe1#
or
23. Qf1 Qxf1# |

| | patzer2: In case of 21. Kh1, <SuperPatzer77> gives a forcing double attack combination in his second post where Black winds up with a Queen, Rook and Bishop for a Bishop. So that, in addition to the back rank mate threat after 21. Qxf2 Qa8+  , is another compelling reason for White's immediate resignation. |
|
| May-05-09 | | YoungEd: Thank goodness for Mondays and Tuesdays so that I can feel like a strong chessplayer. Back to Patzerville tomorrow, though... |
|
| May-05-09 | | JG27Pyth: Black to move... so I spent awhile looking at White's threats: the bishop skewering queen and rook from g5 and White's various back rank threats...and saw that Black has d5 jamming all White's signals... and then Queen on f3 and if I could get another move Qg2# mate... but White can wriggle off the hook with... hey... wait...come on ...it's Tuesday
*scritch scritch*
Oh Bxf2+! ok... got it...
:) |
|
| May-05-09 | | WhiteRook48: found 20...Bxf2+!! but after 21 Qxf2 I had no idea of a follow-up |
|
May-05-09
| | beenthere240: I wasted time with moves like 20...dr (to interfere with the LSB and permit 21...Qf3. Needless to say they didn't work. Then I tried 20...Qxf2+, which of course doesn't work since the rook is in the wrong place. After finding a number of selfmates, I finally hit on 20...Bxf2+. |
|

 | | kevin86: Here is a real game of dancing bishops. A full one third of all moves are by bishops. It is just that the lethal move be made by a clergyman. 20...♗xf2+! After ♕xf2+ and white's queen blocks the escape square and while three pieces can interpose,no two can do so at the same square and so are lopped off one at a time. Mate will come at e1---sooner or later. |
|
| May-05-09 | | YouRang: I found it after going down a couple dead-ends. :-|
First, I wanted to find a way to block or deflect white's LSB so that I could play ...Qf3. But the only way I could see was ...d5, which is simply met by Bxd5. Then I thought about trapping white's DSB with ...g5, which is simply met by Bxg5 (the bishop is protected by Rb5). So, next I tried to deflect the rook, but nothing worked, e.g. ...a6 is met by Rg5 (and I think Rd5 works too, since ...Qf3 is answered by Rc5, but it might be tricky). Finally, I started looking for ways to deflect white's Q. My rook is useless for that, so I finally conidered 20...Bxf2+! forcing 21.Qxf2, and now I have 21...Qa1+ and white is doomed. So it was an easy puzzle except for the distractions. :-) |
|
| May-05-09 | | KastelFhlor: 20 ...Bxf2+, followed by 21 ...Qa1+ |
|
| May-05-09 | | jheiner: Oh, I got killed. I missed the Qe8# threat. Just glanced and saw 20...d5 21.Bxdb Rxd5 22.Rxd5?? [22.Qe8#] Qf3 and stopped searching as (other than the back-rank mate...Qf3 is indefensible. Lazy today. Need to check for counterplay always. |
|
| May-05-09 | | lightbishop c5e6: Very easy. 20... Bxf2+!
Now if(a) 21. Kh1 Bxe1 wins the Queen,
and if(b) 21. Qxf2 Qa1+ leads to mate in 3 more moves: 22. Rb1 Qxb1 23. Bc1 Qxc1 24. Qf1(Qe1) Qxf1#(Qxe1#) |
|
| May-05-09 | | MaczynskiPratten: Nice finish. I looked up Frank Parr and found F Parr vs G Wheatcroft, 1938, which I had never seen before and strongly recommend to anyone else who hasn't - a lovely game! (Again, featured by Irving Chernev). How the heck did Chernev find the time to discover all these obscure games and produce works like "1000 Best Short Games of Chess" in the days before chessgames.com? |
|
| May-05-09 | | SuperPatzer77: 20...Bxf2+!!, 21. Kh1 Bxe1, 22. Bf4 (preventing 22...Qf1#) Qa1! (threatening the discovered mate) White's four tries are below:
1) 23. Be4 (trying to stop the rank mate) Bb4+! (blockading the White Rook from getting to the b1 square and forcing the mate), 24. Bb1 Qxb1+, 25. Bc1 Qxc1# 2) 23. Kg1 Bxg3+! (forcing the mate), 24. Rb1 Qxb1+, 25. Bc1 Qxc1# 3) 23. Be3 Bf2+! (blockading the White Bishop from getting to the g1 square and forcing the mate), 24. Rb1 Qxb1+, 25. Bc1 Qxc1# 4) 23. Bg2 Bf2+, 24. Rb1 Qxb1, 25. Bc1 Qxc1+ 26. Bf1 Qxf1# SuperPatzer77 |
|
| May-05-09 | | Big Easy: Not hard at all today. I found it more easily than yesterday. Once I contemplated 20... Bxf2+ it became obvious. |
|
| May-05-09 | | ruzon: <YouRang> saved me from having to post, except that I started by considering 20...Qxf2+ and 20...Bxf2+ without seeing anything. Then I came back to Bxf2+. |
|
| May-05-09 | | Sabinas: Nice...I jumped on the opening move (Bxf2) quick but it took me a moment to find the follow-up Qa1+ that made it worth while. I wonder when Parr saw it...could it possibly be before move 17? |
|
| May-05-09 | | muralman: Back in the stirrups today, after some time away. This was a good mind stretcher. Bring on Sunday. |
|
May-05-09
| | beenthere240: <Sabinas> I bet Parr saw it right after 19. Rb5? which makes the whole combination possible by weakening the back rank. If the rook stays home on the first rank, the Queen check on a1 is impossible and the combination doesn't work. After 19...Bb6, there's nothing white can do to protect the f2 square. |
|
May-05-09
| | beenthere240: except of course 20. Rxb6, which effectively conceeds the game by going down the exchange and a pawn. |
|
| May-05-09 | | Eduardo Leon: 20. ... Bxf2+ 21. Qxf2 Qa1+ |
|
| May-05-09 | | vikinx: Found it immediately: 20. ...Bxf2+ wins the game. |
|
May-06-09
 | | gawain: Really sweet. 21...Bxf2+ is the obvious move to try just to see what happens. And I saw the followup 22... Qa1+ right away. What's sad is that poor White thought he had the f2 square covered after 20 Qe1... |
