|Apr-23-16|| ||Penguincw: Happy St. George's Day? (and also happy 400th "anniversary" of Shakespeare's death)|
I usually don't like trying late week puzzles, but for this one, material even, went with 35...gxf2, but that runs into 36.Qxf2 Qg2 37.Qxg2 Bxg2 38.Rg1, material remains the same.
|Apr-23-16|| ||dfcx: this one looks easier than yesterday's.
Black is down a rook, but has a deadly attack with 35...Rxd2+
A. 36. Rxd2?? Qxf3#
B. 36.Kxd2? Nxf3+ wins the queen
C. 36. Qxd2 Qxf3+ 37.Ke1 Qg2 and white has to give up a lot of material to avoid mate.
|Apr-23-16|| ||An Englishman: Good Evening: A repeat--eight years ago, I wrote that it was too easy for a Sunday. Now it's too easy for a Saturday. Perhaps with the advance of chess knowledge, someday we shall call this puzzle too easy for a Monday!|
However, 30....Black to Play will remain impossible forever, esp. insofar as the correct follow-up is not the Bishop capture.
|Apr-23-16|| ||King.Arthur.Brazil: I agree with dfcx I see the same line before. But I didn't thought about Qd8+ etc. neither the Nf3+ and Nd4+. Now, looking at Qd8+ and the Ng5, it seems OK this moves then Qxf1 Rxf1 Bxf1, B... moves and the P goes to f1 = Q.|
|Apr-23-16|| ||not not: i would take his knight with my rook and invade with queen via f3|
lots of calculating lines though; if he takes with king, fork wins, but if he retakes with queen it gets messy
|Apr-23-16|| ||Cheapo by the Dozen: I thought ... Bg4+ would be in the mix.
Anyhow, it's pretty easy to find the first couple of moves, because it's pretty clear that nothing else could work.
|Apr-23-16|| ||AlicesKnight: ...... Rxd2+ is possible; if 36. Rxd2 then ....Qxf3# while Kxd2 allows the N fork, so 36.Qxd2 Qxf3+ 37.Ke1 and where now? - Oh, nice, didn't see that....|
|Apr-23-16|| ||morfishine: Remove the defender <35...Rxd2+>|
Now, I'll remove myself to fridge and fetch another beer
|Apr-23-16|| ||scholes: 30 ..Rd3 is spectacular|
|Apr-23-16|| ||alphee: I got the first move but my guess was that white would take with the rook, hence the following was a bit different.|
|Apr-23-16|| ||agb2002: Black has a bishop for a rook and a knight.
White threatens 36.Qxh1.
The first idea that comes to mind is 35... Rxd2+, removing one defender:
A) 36.Rxd2 Qxf3#.
B) 36.Kxd2 Nxf3+
B.1) 37.Kc2 Nxe1+ 38.Bxe1 (38.Rxe1 Qg2 wins the bishop) 38... Qf3 and, although the material is balanced, the advanced linked passed pawns should prove decisive.
B.2) 37.Kd3 Nxe1+ 38.Bxe1 (38.Rxe1 Qf3+ wins the bishop) 38... Qf3+ followed by Qg4 and f3 looks winning.
B.3) 37.Ke2 Nxe1 38.Rxe1 (38.Bxe1 Bf1+ 39.Kd2 Qg2+ 40.Ne2 Bxe2 wins decisive material) 38... Qh2 wins decsive material.
C) 36.Qxd2 Qxf3+ 37.Ke1 Nxe4 38.Nxe4 (due to Nxd2 and gxf2+) 38... Qh1+
C.1) 39.Bg1 Qxg1+ 40.Ke2 Bg4+ 41.Kd3 Qd4+ 42.Kc2 Qxe4+
C.1.a) 43.Kb2 Bxd1 and the passed pawns should be enough to win. White doesn't seem to have perpetual: 44.Qd8+ Kh7 45.Qh4+ Kg6 46.Qg4+ Kf6 47.Qh4 Kf7 48.Qh5 Qg6.
C.1.b) 43.Qd3 Bxd1+ 44.Rxd1 Qf2+ (44... Qxd3+ 45.Kxd3 and the white king is ready to control the light squares around the passed pawns)
C.1.b.i) 45.Rd2 e4+ wins decisive material.
C.1.b.ii) 45.Qd2 e4+ followed by Qxd2, f3, Bd4 (or Bh6) looks winning.
C.1.b.iii) 45.Kc1 Qxc5+ with three connected pawns for the exchange looks winning.
C.1.b.iv) 45.Kc3 e4+ wins.
C.1.b.v) 45.Kb1 Qd4 (45... g2 46.Qd8+ Kh7 47.Qd3+ (47.Qh4+ Qxh4) 47... Kh6 48.Rd6+ Kg5 49.Qg6+ Kh4 50.Rd1 Qg3 51.Qh7+ looks bad for Black) to create mate threats (with e4) and trade queens because the white king is not near the passed pawns.
C.2) 39.Ke2 Qxe4+ 40.Be3 f3+ 41.Ke1 f2+ 42.Ke2 Bg4+ 43.Kf1 Qh1#.
|Apr-23-16|| ||agb2002: I didn't remember this game but it seems I had problems with Qd8+ again.|
According to Stockfish, after 37... Nxe4 38.Qd8+ Black loses the advantage.
|Apr-23-16|| ||schachfuchs: Yes, like an Englishman I would transform this (not really) very difficult Saturday puzzle 35....? into an insane Sunday 30....?|
|Apr-23-16|| ||Once: Now that's a weird sensation. It seems that I was here in October 2008. That's 7 and a half years ago. Where did those years go? |
I didn't fully solve it this time either.
|Apr-23-16|| ||WorstPlayerEver: Well, Ï found it pretty complicated in practise. I noticed all these White pieces cluttered together and was so impressed by it that I totally ignored the weakness of f3. Oh well..|
|Apr-23-16|| ||kevin86: A fine attack by black.|
|Apr-23-16|| ||The Kings Domain: Good puzzle. Gotta get rid of that pesky horse.|
|Apr-23-16|| ||devere: After 35...Rxd2+ 36.Qxd2 Qxf3+ 37.Ke1, the best move seems to be 37...Bf6 keeping the White queen out of d8

Then can follow 38.Qe2 Qg2 39.Rd3 (if 39.Kd2 gxf2 40.Kc2 Nxe4 and White can't capture the knight either way due to 41...f1=Q) f3 40.Qe3 Nxe4 41.Nxe4 gxf2+ 42.Nxf2 Bg5

White can throw in 43.Rd8+ Kf7 if he wants, but then he is out of reasonable checks and Black wins.
|Apr-23-16|| ||Longview: Not bad <Once> good survival in this day and age of competition! |
Got the first move, calculated all but the response of white but it still fit what I intended but I was surprised by Q-g2. I was expecting Bg4+. I guess that is not as helpful as what was played.
|Apr-23-16|| ||alfiere nero: I'm out of my league here (although I did see the first couple of moves), but isn't 40 Qd3 better than Qd8 in the actual game?|
|Apr-23-16|| ||mel gibson: This game shows the power of a Rook
to enter the game and completely smash up the opponent.
I saw it immediately.
|Apr-24-16|| ||gabriel112000: I solved it!|
|Apr-24-16|| ||CHESSTTCAMPS: Black's down a full rook, but white's king is in full flight. It's not hard to see that black has at least a draw, starting with 35... Rxd2+, but beyond the first couple of alternatives, it stops being easy:|
B.36.Kxd2 Nxf3+ 37.Kc2 Nxe1+ 38.Bxe1 (Rxe1 Qg2 39.Kb1/Rf1 gxf2 is winning by at least a piece) Bg4 39.Rd8+ Kh7 40.Bxg3 (otherwise 40...g2 wins) Qg2+ 41.Rd2 Qxg4 is effectively a piece ahead and has a protected passed f-pawn.
B.1 38.Ke2 Nxe1 39.Rxe1 (Bxe1 Bg4+ wins Rd1) Qg2 wins the pinned bishop as in first parenthesized main line.
C.36.Qxd2 Qxf3+ 37.Ke1 Qh1+ is certainly at least a draw.
After 37... gxf2+ 38.Qxf2 appears to hold. The strongest continuation appears to be 37... Qg2 threatening both 38... Qf1# and Nf3+. Best I can find is 38.Qd8+ Kh7 39.Kd2 (not Qxg4 Qxf2#) Qxf2+ 40.Kd3 Qe3+ 41.Kc2 f3 and the passers appear to be winning.
Time for review...
|Apr-24-16|| ||CHESSTTCAMPS: I also considered 39... gxf2 40.Rf1 (numbering without the repetition of moves) but missed the strength of Nf3+.|
|Apr-25-16|| ||TheBish: Amazing finish.|
