 | | Phony Benoni: After <24.Qd6>:
click for larger view<24...Ng6> loses more material to 25.Na3. Instead, the "American Chess Bulletin", May / June 1937, p. 49 gives 24...Nc6 defending that threat, at least. ACB also adds an extra move near the end: <45...h5 46.Nd4>. |
|
| Jul-04-22 | | Brenin: 14 d6, forking Q and B, forces 14 ... Bxd6 and then 15 Nf5 wins the B, as it has no place to hide, and nothing except the Q to protect it. Black can win a second P with 15 ... Qb7 16 Nxd6 Qxb2 but then 17 Qc4 wins back the c-pawn. |

 | | ChessHigherCat: I got it but I had to try out a few differernt approaches first because it was a novel configuration. Interesting Monday puzzle. |

| | ChessHigherCat: Phony Benoni??? Now I know why the Russians call Sunday Воскресенье (resurrection day)! |

 | | raymondhow: After the first three moves, I wanted to play 17.Qa1 which the engine says is +5 for White, just as good as the game move. But this is not a Monday puzzle, more like Tuesday. Something is out of sync with the POTDs. |

| | ChessHigherCat: How, Raymond! This is a bit trickier than the average Monday, I agree, but the Sunday puzzle wasn't really out of sync, it's just that they accidentally put move 18 instead of "16. White to move". That would have been difficult to see, despite all the people who claim it would have been only moderately difficult (with the benefit of 20-20 hindsight :-) |

 | | FSR: Can't accuse Steiner of resigning too early. You're a piece down against the world champion (OK, I guess at that moment he was former world champion, soon to be world champion again). Show some respect. |

 | | Check It Out: 14. d6 Bxd6 15. Nf5 traps the bishop with no way to counter. Bit of an unusual puzzle. |

| Jul-04-22 | | mel gibson: That is more difficult than usual for a Monday. I knew it was either 14.d6 or 14. Nf5.

You're a piece down against the world champion (OK, I guess at that moment he was former world champion, soon to be world champion again). Show some respect.> My thoughts precisely! I was thinking either he wanted to get the move count up (as opposed to resigning on move 14 or 15, somewhat embarassing) or maybe the first time control was 45 moves and he reached that on his penultimate move. Or maybe too angry at himself for blundering a piece (although a nifty tactic, not too hard to see) and he was punishing himself by playing on. Who knows? Some people just never resign. |

 | | agb2002: White has a bishop and a knight for the bishop pair. Black's dark square bishop is defenseless and has reduced mobility. Hence, 14.d6 Bxd6 15.Nf5 wins the bishop without any compensation. For example, 15... Qb7 16.Nxd6 Qxb2 17.Qc4 Qa3 18.Nxe5 a5 19.Nxc8 Rxc8 20.Nxf7. |

 | | boringplayer: Was there anything wrong with 18.Nc8, followed by 19.Ne5? |
|
| Jul-04-22 | | saturn2: d6 is a usefull move for black in the Benoni. Now it is white's turn. 14.d6 followed by Nf5 win B for P |
|
| Jul-04-22 | | Brenin: On move 17 Alekhine had a choice of Qc4, Qa5 and Qa1, all defending the P on c3. The first two are more active, and they also attack Black's P on c5. I think Qa5 is marginally the better of the two, since it prevents 17 ... a5 which allows Black to use a6 to develop his Q-side pieces, and/or to advance the a-pawn until it becomes a promotion threat. Either way, White is clearly winning, but it would be interesting to know how Alekhine decided on Qc4. |
|
| Jul-04-22 | | cocker: White to play and win (in 33). Poor Steiner, another victim of Nazi Germany. |
|
| Jul-04-22 | | parch: Did not see it at first,
14.d6 B:d6 15.Nf5 wins the Bishop. |

Either way, White is clearly winning, but it would be interesting to know how Alekhine decided on Qc4.> Indeed interesting choice. Qc4 evaluates best in short analysis <on> the move, if by almost negligible margins, but changes his mind only half a ply later, agreeing White's options are all decent. Having said that, I'm not really sure if Qa1 is that much more 'inactive' than the other two, given it forces a queen trade or her tucked away from the fray, and during all that e5 is still in. In fact, SF gives the trade as only reasonable option. Qb6 is the only sensible retreat, but Nxe5 is just the most logical move and crushing due to following with Nexf7 or Nec4. Qa5 might actually be better, as it forces the exchange 17....Nc6 18.Qxc5, in White's favor. After this move, analysis value increases. I actually prefer Qa1 for simplicity. Per SF short analysis post-move:
17.Qc4 a5 18.Nxe5 Ba6 19.Qxc5 +5.05
17.Qa1 Qxa1 18.Rxa1 f6 19.Nd2 +5.03
17.Qa5 Nc6 18.Qxc5 Rb8 19.Nxe5 +6.30 |
|
| Jul-04-22 | | TheaN: Oh also, <14.d6 Bxd6 15.Nf5 +-> is certainly a unique but useful Monday, and Steiner probably should have thrown the towel earlier. |
|

 | | perfidious: An odd Monday POTD, with a short, forcing line which produces a won game; hardly standard fare generally in any case, and not the typical slam-bang Monday. As others have noted, Steiner showed himself to be rather a bitter-ender in this tilt. |
|
| Jul-04-22 | | Besrqe: <Brenin: ...White is clearly winning, but it would be interesting to know how Alekhine decided on Qc4.> As to why Alekhine chose to play Qc4, I see it really simply and think of it as Alekhine's way of being snarky in return to Steiner not resigning after his obvious blunder. See, although Steiner dropped the Bishop for the White dpawn, he did go into a line where he was able to immediately capture White's b2 pawn and console himself in thinking that he got 2 pawns for the Bishop. He's also about to grab a third pawn on c3. So, in choosing how to protect c3, I would do it just like Alekhine did and beeline right for the c5 pawn so I could say, "Wait, Steiner. You only got 1 pawn for the piece." LOL :D |

| Jul-04-22 | | roberto146: Um, a 33-move 'Very Easy' Monday puzzle ending in a resignation? Aren't they usually a briefly challenging one or two move forced checkmate? I am puzzled.
Sunday's Monday puzzle was good though. |
|

 | | eternaloptimist: This puzzle took me longer to solve than the usual easy Monday puzzles but I solved it. Although I chose 17.♘xc8 instead of ♕c4. Although the move that I chose still wins |

| | ChessHigherCat: I know the Alekhine fanboys always make lame excuses for him, but the Wiki bio (https://www.wikiwand.com/en/Alexand...) makes Fischer look like the head of the Antidefamation League by comparison. Seeing how the Jewish Steiner eventually died in a concentration camp as a result of the ideology of racist psychos like Alekhine, I don't see any reason why Steiner should have tried to show him respect by resigning. In fact, shooting Alekhine in the face would have been more logically consistent |
