|Feb-17-11|| ||queenfortwopawns: Easy, which is why I didn't bother getting it right.|
|Feb-17-11|| ||johnlspouge: 9...c5 is not a good move. Instead of controlling d4 (probably its intention), it permits White to clear away the White a- or b-P, freeing his Rs to attack the Black K. |
Toga's evaluation for White increases from about +0.25 P before 9...c5 to +0.6 P after.
|Feb-17-11|| ||hedgeh0g: Nice, unusual combo for a Thursday. Always examine those forcing checks!|

Lest we forget! Thanks for the reminder, <agb2002>.
|Feb-17-11|| ||kevin86: My move here is 29 ♘e7+ ♗xe7 30 ♕a6!! and mates quickly,correct?|
|Feb-17-11|| ||kevin86: On the other hand,the black queen can move and allow the king to escape ,so it is not the best-the text is...|
|Feb-17-11|| ||al wazir: <rilkefan: <What was wrong with 16. Rxe5 ?> I guess ...Bd6 17.Ra5 wins the tempo back, if at the cost of improving Black's bishop and pressure on the kingside - but how about Bb4>|
16. Rxe5 Bd6 17. Ra5 Bb4 18. Ra8+ Kd7 19. Rxd8+ Kxd8 20. Ne5. Now, if 20...Bxd1, then 21. Nxc6+ bxc6 22. Rxd1. I can't believe white isn't winning here -- but of course the way the game worked out was even better.
|Feb-17-11|| ||triangulation: I think I've got this one. both Ne7 and Qa2 seems to me to be winning moves. |
I looked at the puzzle for a long while when I realised that only the rook on a8 was protecting the king from Rb8#
From then it was easy.
Time to check....
|Feb-17-11|| ||triangulation: Ok so maybe Qa2 doesn't win after all. I liked that one better. Might have gone for that in my own game. so i give myself zero today.|
|Feb-17-11|| ||gropek: I got the answer for the puzzle, but it took me a long time.|
Before finding the right idea, first I tried ideas with Qb3,Qa2,Qa6, Ne7,etc.
Only then, by realizing that everytime my ideas didnt work because after the black queen moves, the king can always run to d7, I decided to look for ways to do something before the black queen can have a chance to move.
Then it was easy to pick the right ideas :)
|Feb-17-11|| ||jsheedy: I saw the win almost immediately but wasted time trying to figure out if Rb8+ should come before or after Be7+. Since black's forced responses were the same either way, I'll take full credit. I never considered Qa2 or Qb3, since the pinned black queen was crucial, and to allow it to be unpinned by a non-checking move would squander the win.|
|Feb-17-11|| ||gawain: Oh, I nearly got it. Saw 29 Ne7+ but would have wrongly followed up with 30 Qa6 Hoping for 30...Rxa6 then Rb8# Not good enough.|
|Feb-17-11|| ||M.Hassan: "Medium" White to play 29.?
Forces are equal.
I think this is one of the rare instances that I saw the solution almost instantly!( almost in 15 seconds! to be quite honest) I hope I am right:
29.Ne7+ Bxe7 (the only move to prevent mate. Queen is pinned)
|Feb-17-11|| ||stst: Slightly different order, same effect:
29. Rb8+ RxR, 30.Ne7+ BxN, 31. Qa6+ Rb7, 32. QxR#
The line 29. Qa2 etc meets tough defense e.g. 29..Ba3 or 29.. Qa4, and even if it works, leads to a long wait and less forceful attack.
Nice mating net, but pretty obvious, about 1 star level.
|Feb-17-11|| ||takchess: The pin is mighter than the sword.
Here is what I came up with after much noodling.
Ne7+ bxe7 (forced)
Qa6 check and after an ineffective attempt to block the Queen takes for the mate.
The N & R check move order is not important.
Themes: Removal of the guard and the Pinned cannot Protect.
|Feb-17-11|| ||Whitehat1963: Couldn't figure out Tuesday's puzzle, but I saw this one pretty quickly. (Might have helped that I'd suggested in the first place, of course, but I'd forgotten it by now.)|
|Feb-17-11|| ||patzer2: Using a pair of decoy sham sacrifices, White forces mate-in-four, with 29 Ne7+! Bxe7 30 Rb8+ Rxb8 31 Qa6+ Rb7 32 Qxb7#, to solve today's Thursday puzzle.|
|Feb-17-11|| ||DarthStapler: I got the first move but I picked Qa6 instead of Rb8+|
|Feb-17-11|| ||gazzawhite: <DarthStapler> Me too. I even considered 30...Qxh3+ but I only thought it prolonged mate, not noticing that it allowed the black king to escape.|
|Feb-17-11|| ||WhiteRook48: I missed the Qa6 idea|
|Feb-17-11|| ||agb2002: <johnlspouge: < <agb2002> wrote: The maneuver reminds me of Bird vs Morphy, 1858. >|
Lest we forget! Thanks for the reminder, <agb2002>.>
<Phony Benoni> also mentioned that game: the sacrifice of a piece to unblock the queen's path to the other side is a memorable maneuver.
|Feb-17-11|| ||alachabre: Situational assessment:
White absolutely rocks with advantage in space. Ne7 is a semi-smothered mate, if the B can be cleared. Black has no apparent counterplay, with the exception that White's queen is en prise. Not for long, I suspect.
29. Rxc7+ Bxc7?
29. ... Kxc7 defends.
Hang on, what do I see here? Nope, I hallucinated an epaulette mate.
Here it is, a double-deflection sacrifice:
29. Ne7+ Bxe7
30. Rb8+ Rxb8
31. Qa6+ Rb7
And the order of 29 & 30 can be reversed with no loss of tempi, both moves are equally forcing to the reply. Yesterday's puzzle seemed harder, and I noticed some of the regulars struck out on it as well.
|Feb-17-11|| ||Ted the Cat: Hot damn, got this one quickly.|
|Feb-17-11|| ||hstevens129: 29.Ne7+ Bxe7 30.Qa6 Qe8 (not ...Rxa6 31.Rb8#) 31.Rb8+ Kd7 32.Qb5+ Ke6 33.Qc4+ Kd6 (or Rd5 34.Qxd5#) 34.Qd5#|
|Feb-17-11|| ||hstevens129: Just realized:
29.Ne7+ Bxe7 30.Qa6 Qa4 refutes my previous solution.
e.g. 31.Qxa4 Rxa4 32.Rb8+ Kd7; or 31.Rb8+ Kd7; or 31.Qe6+ Qd7
