| Mar-04-16 | | WorstPlayerEver: I thought White could play 26. Bc2, so my imagination stopped there. Well, I never learn it anyway. |
|
| Mar-04-16 | | The Kings Domain: Didn't get this :-). Good and instructive puzzle, pretty deep in its simplicity. A fine reminder, especially to beginners, that not all good moves have to end in mate. |
|
| Mar-04-16 | | dfcx: I was so close and did not see the fork after 26.Bc2 Rxd1 27.Bxd1 Rd8 28.Bf3 Rd2+! 0 point for me today. |

 | | PawnSac: < Phony Benoni: <Penguincw> In the 22...Qxh2+ line, White has options such as 24.Be2. Doesn't save him, but does complicate things a bit. > yes, agreed. ..Nxh2 is stronger because of the triple threats
..Nf3+(fork), ..Qxg3+, and ..Bxd1+ |

 | | Sally Simpson: Hi P.B.
"Phony Benoni: The bishop pair can perform wonderful feats of coordination, but they just can't get the hang of mutual protection." The finish reminded me of the final position in...
A Gudmundsson vs Fischer, 1960
Game 19 M60MG's.
White to play: (he resigned)

| | PawnSac: < morfishine: I thought Black was forced to play 22...Rxd3 to prevent the Queen-trapping 23.Bf1 > I too considered ..Rxd3 at first (even if just to eliminate it as a possibility), but very quickly realized it does not produce the desired results. My second candidate move was ..Nxh2. In the case of your concern Bf1, if after 22. ..Nxh2 23. Bf1 then Qxg3+ 24. Bg2 Nf3+ 25. Kf1 Rxd1 26. Rxd1 Nh2+ 27. Kg1 Bxd1 28. Qxd1 Ng4 (with the threat Qxg2 and Ne3+ fork)
29. Qd2 Ne3 30. f5 Nxc4 31. Qc1 Nxb2 32. Qxb2 Rd8 33. Qc1 c4 and white is completely lost. I haven't done any computer checks here, just tossing it out there. But it certainly seems not only does black win the exchange but has sufficient initiative and play to drive home the full point easily. |

| Mar-04-16 | | whiteshark: There you have it: The ♖ is an attac♔ piece |
|
| Mar-04-16 | | kevin86: The bishops are tangled up and the rooks take advantage. |
|
| Mar-04-16 | | King Harvest: This feels like one of those positions OTB where your opportunistic tactical radar goes: there's something here! surely there's something here... but what? And you look over a few sac ideas and go... ehh, I guess there's nothing after all. Well done by Kerr.
Like others I tiptoed up to the correct line but failed to see/calculate to the unstoppable rook fork that wins the exchange. |
|
| Mar-04-16 | | BOSTER: The real puzzle was:
why white didn't play 22.Bf1 instead to move the rook under discovered.

After forced line
22...Qxh2 23.Qxh2 Nxh2 24.Kxh2 Rd2+ 25.Kh3 Rxb2 26.g4 Bg6 27.f5 Bh7
maybe wbite was better. |
|
| Mar-04-16 | | saturn2: <morfishine .. to prevent the Queen-trapping 23.Bf1> As far as I see this was not a real threat if white were to play because black could play 23...RxRd1
and neither after whites
24.a QxR Qh2# nor
24.b RxR Qxh2 25 QxQ NxQ 26 KxN BxRd1 nor
24 BxQ RxRe1
white has an advantage. |
|
| Mar-04-16 | | tonsillolith: <Sally Simpson> good call! There is a lot in common between those games, especially the finish. |
|
| Mar-04-16 | | catlover: <al wazir: I feel so stupid. I didn't see that last bit where black wins a ♗.> Me, too. I kept looking for a mating combination. |
|
| Mar-04-16 | | morfishine: Yeah, U guys are right, I should spend more time mentally analyzing and visualizing, not just doing the "15-seconds and how did I do format" I used to do that

| Mar-04-16 | | stst: Difficult! - In the sense of the very hidden "elegant" play...
The N is blocking the B to take R@d1, and has no good place to go...
R takes B@d3 is not worth-while...
The only obvious play is by "brute" -
22...........Qxh2+
23.QxQ NxQ
24.KxN BxR
25.RxB Rd7 ready to double R
...
After these exchanges..
Black got 2R vs White's R+2B, but Black got 1 more pawn... may not be enough to win.... Then if Nxh2 first, pretty much the same result...
The N is meant probably for either a fork, or a smothered mate, but I missed it... Exploiting the e4 pawn?.... |
|
| Mar-04-16 | | stst: Curious enough, the game proceeds as I predicted. |
|
| Mar-04-16 | | dark.horse: I work on these positions strictly in my head. The result of this one reminds me of what Soltis said was the weakness of computers, that they compute positions deeply but evaluate positions poorly. I computed the combination right up to 24...Bxd1 25.Rxd1 Rd8 26.Be2 Rxd1 27.Bxd1 Rd8. Then I stopped. Since I didn't see that the bishop was about to be forked I rejected the entire line. I assumed that the final position was quiescent, which it was not. It still had some "juice". |

 | | ajk68: Ugh. Saw the idea but had the wrong move order. Started with ...Rd7, but that allows white to wiggle out of it with a simple Rd2. |

 | | Phony Benoni: I found this game while preparing a batch from the 1956 US Open, and immediately submitted it specially with a note that it might be POTD-worthy. Didn't expect as late as a Friday, but it seems to have caught enough people. It's hard not because the key point comes on the fourth move; indeed, most any seasoned puzzle-solver will consider the line. What's hard is that <25...Rd7> looks so slow and ineffective that you tend not to take it seriously. I stared at the move for a couple of minutes thinking, "So what?", then after finally seeing the point analyzed a couple of minutes more in the fervid belief that White must have a way out. I know nothing more about Derwin Kerr, but the man obviously had some strong tactical vision. |
|
| Mar-05-16 | | FlashinthePan: I found it after losing minutes looking for a winning combination. A pretty counterintuitive finish in that position. |
|
| Mar-05-16 | | luftforlife: <Phony Benoni>: Great submission! Both the game and the kibitzing it has elicited are instructive and inspiring. It seems Derwin Kerr was twenty years old at the time of this brilliant victory. In The California Chess Reporter, Vol. VI, No. 5, December 1956, there is a three-paragraph write-up about him by Charles B. Walker at page 96, followed by the game Kerr-McCormick, annotated by Kerr, at pages 96-97. According to Walker, Kerr had been attached to March Air Force Base at Riverside, California, where he played for the Riverside club and won eighteen out of nineteen games in a simultaneous exhibition against local players. Upon his transfer to a base in Texas, Kerr was en route through Oklahoma City when he stopped to play in the U.S. Open, where he made a solid showing in his first major tournament. Here's the link:

Thanks so much for this compelling game and POTD. Kind regards. |

| Mar-05-16 | | Ayaend: 22th white move Bf1 Black obviously see the continuation with queens echange on h2 and after rock is going on d2 with check and take the Bishop on b2 but. I think white is clearly better after 21.Bxf6 right? |
|
| Mar-06-16 | | patzer2: Catching up on puzzles I missed this week. Once I found 22...Nxh7!, the follow-up pinning combination solving the Friday March 4, 2016 puzzle flowed naturally for me. The one finesse, other than the moves played, is 26. Bc2 Rxd1 27. Bxd1 Rd8  with a decisive double attack threat. White's game starts to go sour with 21. e4? allowing 21...Ng4  (-0.40 @ 18 depth, Deep Fritz 15). Instead, 21. Bxf6  (+0.95 @ 20 depth, Deep Fritz 15) gives White the upper hand. White is completely busted after 22. Rad1?? which allows 22...Nxh2 (-3.84 @ 30 depth, Stockfish 6). Instead, 22. Bf1  (-0.35 @ 20 depth, Deep Fritz 15) keeps the first player in the game. |
|
| Mar-07-16 | | saturn2: <patzer2 Instead, 22. Bf1 (-0.35 @ 20 depth, Deep Fritz 15) keeps the first player in the game.> I had to look twice, because at first look I thought the queen is really caught after this move, but no.. there black rook forks Kh2 and Bb2 after the exchanges on h2. |
|
| Apr-23-17 | | clement41: 26 Bc2 or 26 Be2 are not enough due to 26...RxR 27 BxR Rd8 hitting the Bd1 and threatening ...Rd2+ forking the other bishop |
