|Apr-15-09|| ||zoned87: I see I see... patriot do you have email mine is firstname.lastname@example.org. Would be very helpful if you played some games with me. Also I wouldn't have moved my queen there so how would I know black would get a stalemate?|
|Apr-15-09|| ||WhiteRook48: 45 Qb6+ isn't even a real puzzle! The puzzle should be Black to play, 45...?|
|Apr-15-09|| ||YoungEd: Hey, everybody! I'm as good as Chigorin today! :) Actually, that's a lie; I would have botched the game 30 moves earlier!|
|Apr-15-09|| ||benveniste: With this puzzle, how do you decide that you "got it right?" I saw that ♕g6+ leads to stalemate, so I tried ♔b4. I'm pretty sure that wins, but perhaps not as quickly as b6!|

White to play (45.?) "Medium/Easy"
I almost fell for the trap! I was wondering why this was a two star problem and not easier, and then I found the reason: 45. Qb6+?? -- very tempting because it blocks the check with a check, virtually forcing the trade of queens, leading to a simple won ending for White. Except that it isn't forced! Black has the stalemate resource 45...Ka8! and now if 46. Qxc7 it's stalemate, or 46. Ka6 (only other move) 46...Qc8+! 47. Ka5 Qc7! repeats the position.
Add this to the fact that at first, I thought that 45. b6 was a blunder! I thought that after 45. b6 Qe5+ draws for Black, because it forces 46. Qxe5 fxe5, creating a passed pawn for Black. I was thinking that White couldn't make progress, since advancing the king too far would allow Black's pawn to queen, but a little analysis shows that White queens first (or mates) in all lines:
45. b6! Qe5+ 46. Qxe5 fxe5 47. Kb5 Kb7 (advancing the e-pawn allows White to simply go after it, while White doesn't go after the e-pawn unless it advances, since Black can always play f7-f6) 48. a5 Kb8 (48...f6 49. a6+ is similar) 49. a6 Ka8 50. Kc6 Kb8 (or 50...e4 51. Kc7 e3 52. b7+ Ka7 51. b8=Q+ Kxa6 52. Qb6#) 51. a7+ Ka8 52. Kc7 e4 53. b7+ Kxa7 54. b8=Q+ Ka6 55. Qb6 mate.
So the queen trade after 45...Qe5+ is easy for White. What else? The simple answer is, White wins simply by trading queens at the expense of his b-pawn, advancing the a pawn to a point, then leaving it in favor of gobbling up Black's f-pawns and queening his own f-pawn. For example:
45. b6! Qc8 (or 45...Qc6 46. Qd8+ Kb7 47. Qc7+! or 45...Qb7 46. Qd8+ Qc8 47. Qxc8+) 46. Qd6+ Ka8 (or 46...Kb7 47. Qc7+!) 47. b7+! Qxb7 (or 47...Kxb7 48. Qa6+) 48. Qa6+ Qxa6 49. Kxa6 and wins, as described above.
|Apr-15-09|| ||TheBish: I forgot the best defense (after 45. b6), 45...Qe7, but (as it's already been pointed out), White wins after 46. Qf4+, i.e. Ka8 47. Qc7! Qe1+ 48. Kb5 Qe2+ 49. Kc6 Qe4+ 50. Kd7 Qxf5+ (or 50...Qd5+ 51. Kc8! Qxf5+ 52. Kd8 Qd3+ 53. Ke8 is similar) 51. Ke7 Qe4+ 52. Kf8 Qb4+ 53. Kg8 Qg4+ 54. Kh8 and Black is out of checks. Now, White doesn't have to worry about stalemate after 54...Qg8+ (or Qg7+) 55. Kxg8, as Black has a pawn to push!|
|Apr-16-09|| ||TheaN: Wednesday 15 April (delayed)
Material: +/♙\ w: ♕ & 4♙ b: ♕ & 3♙* (ENDGAME) *Black has a doubled-pawn.
Candidates: Qb6†... Qb6†??, <[b6]>
I think that the main part of this puzzle is to spot that the proziac seemingly winning 45.Qb6† actually draws on the spot. 45....Ka8!! 46.Ka6 (46.Qxc7 1/2) 46....Qc8† 47.Ka5, and now, 47....Qc7! 1/2 of course. That is a VERY nice stalemate and repetition trap. White should remain on the upperhand, however, with:
<45.b6 Qe7> by any means the best reply: Black would want to avoid Qd6† and Qd8†. If he doesn't, for example with 45....Qg3 46.Qd8† Kb6 47.Qc7†, White trades Queens and wins due to the Black King's occupation with the a-pawn.
<46.Qc3 > decisive. Black cannot avoid a Queen trade, or mate >_>, and loses. Time to check.
|Apr-16-09|| ||TheaN: 3/3
Hmmrrr. How annoying. OTB, seeing a move like Qe5† would definitely be the case. Why I missed it here is beyond me, but instinctively I noticed that Black could not create anything with the f-pawns as White is ALWAYS in the square (even with a move in reserve). Even so, I should have considered it here. I'm not seeing many Qe7s though, which is still quite a defendable reply compared to Qe5† which loses on the spot. Point for me, because of that.
|Apr-17-09|| ||patzer2: For the Wednesday, April 15, 2009 puzzle solution, 45. b6! is the move White should have played -- instead of falling into the stalemate trap 45. Qb6? Ka8! =.|
|May-29-10|| ||Whitehat1963: Wow! What a game!|
|May-29-10|| ||Once: Hmmm. A déjà vu is usually a glitch in the Matrix. It happens when they change something.|
Today's puzzle of the day is our sixth stalemate in a row. And the game of the day is another stalemate - a repeat of the puzzle of the day of a little over a year ago, which was the third in a sequence of stalemates.
Like buses, policemen and girlfriends, there's never one when you want one, and then three turn up all at once.
Just watch out for black cats.
|May-29-10|| ||randomsac: Oops. So much for the cross-check. This is a funny way to drop half a point.|
|May-29-10|| ||kevin86: White has been bambozzled. The draw is issured by repitition or stalemate.|
|May-29-10|| ||screwdriver: White was thrashing black here, and probably just wasn't thinking about a stalemate this early. Nice plan by black to save himself from a loss.|
|May-29-10|| ||whiteshark: Chigorin was almost dead in 1905.|
|May-29-10|| ||Petrosianic: He was ranked #7.|
|May-29-10|| ||whiteshark: <Petrosianic> No contradiction in terms. But don't take it with a pinch of salt. :D Probably I only meant his 1907 tournaments.|
|May-10-11|| ||iking: 45....? a nice save by black ....

I also considered this the best defence, but I think I found a simpler line, thus:
45. b6 Qe7
Now White threatens 47. Qc7+, exchanging queens or mating on a7. Black can't play 47...Ka8 because of 48. Qc8 mate. The only way to avoid mate or the exchange of queens on c7 is for Black to play 46...Qe5+ 47. Qxe5 fxe5 48. f6!, with a won K+P ending.
|Oct-26-11|| ||Llawdogg: Nice queen sacrifice stalemate from the Master of the Draw.|
|Feb-16-12|| ||Penguincw: One of the more interesting drawn games of the late 19th century/early 20th century.|
|Mar-04-12|| ||RookFile: Beautiful defense by Schlechter.|
|Nov-18-13|| ||tranquilsimplicity: Now that was clever!! What a swindle.#|
|Apr-29-14|| ||KingPetrosian: A brilliant position!|
|Oct-11-15|| ||Mating Net: If you know the Bishop's pawn on the seventh rank stalemate trick, you could find this move. The pattern is the same. |
