| Apr-17-18 | | agb2002: Black is two pawns down.
The white queen is defenseless. Hence, 34... Rf3+ 35.gxf3 Qxf3+ and 36... Qxb3 - + [q vs R+P]. |
|
| Apr-17-18 | | Cheapo by the Dozen: I spent quite a bit of time trying to make a mating net work after ... Rb2 (assuming White doesn't immediately pitch his queen). Finally I looked for another way to win, and it was right there. :) |
|
| Apr-17-18 | | goodevans: <WorstPlayerEver: I had 34... Rb2> Me too. It also wins. E.g.
35.Qc4 Qf2+ 36.Kd3 Qe2+ 37.Kc3 Qc2+ 38.Kd4 Qxd1+ or 35.Qa4 Rxg2 36.Rf5 Qc3+ 37.Rd3 Qe1+ 38.Kd4 Rxf5 |
|
| Apr-17-18 | | Cheapo by the Dozen: 30 Qe4 was necessary, to blockade the pawn. |
|
| Apr-17-18 | | AlicesKnight: 34.... Rf3+; 35.gxf3 Qxf3+ wins the White Q and should be "it". |
|
| Apr-17-18 | | saturn2: Skewer winning Q fo R seen. |

 | | piltdown man: He wouldn't fall for it now, I think. |
|
| Apr-17-18 | | morfishine: <34...Rf3+> and Black picks up the hanging Queen |
|
| Apr-17-18 | | malt: 34...Rf3+ 35.gf3 Q:f3+ and 36...Q:b3 |

| Apr-17-18 | | whiteshark: Is that the same <Fabiano Caruana> who'll fight for the crown in November? Tell me that is not the case... |
|
| Apr-17-18 | | ChessHigherCat: He was just 14,
if you know what I mean,
and the way he played
was not beyond compare... |

 | | Richard Taylor: Everyone makes errors and blunders and no one is excepted from that. Error is essential for chess and life. Error is what makes us what we are. That is, mutations. We are all the result of Error. Which doesn't mean Caruana will win but it means that in the match there will be many errors and it's anyone's guess who will win. |
|
| Apr-17-18 | | sfm: 34.Rd5 was not it, but what should White have played (apart from "everything else")? It is no easy position, having his king walking out there among the heavy guns. |
|
| Apr-17-18 | | patzer2: White's decisive mistake was the not so obvious error 30. R(a)d1?, allowing 30...Rf4! -+ (-5.83 @ 31 ply, Stockfish 8). Instead, 30. Qe4 = (-0.17 @ 33 ply, Stockfish 8) would have held it level. Earlier, the computer prefers 30. Rhc1 Qb2+ 31. Kf1 ⩲ (+0.27 @ 32 ply, Stockfish 8) over the game continuation 30. Rhd1 Bf5 = (0.00 @ 31 ply, Stockfish 8). |
|
| Apr-17-18 | | zb2cr: 34. ... Rf3+ wins the Queen. It's immediate if White steps aside at move 35, prolonged by one move if White plays 35. gxf3, Qxf3+; 36. Kd4(or d2), Qxb3. |

 | | gawain: Looked briefly for a mating combination, then realized that winning Q for R would be quite satisfactory. |
|
| Apr-17-18 | | patzer2: <sfm: 34.Rd5 was not it, but what should White have played (apart from "everything else")?> White was busted after 30. R(a)d1? (should have played 30. Qe4 =), allowing 30...Rf4! -+. By the time it came around to move 34, White had no chance. One amusing alternative is 34. Qd5 (diagram below)

|
| Apr-17-18 | | stacase: Not as easy as yesterday but not too difficult to see what 34...Rf3+ does. White has two extra pawns after the looming demise of his Queen but they are not connected and Black's Queen and Rook are going to pick them off and win the game. White should have thrown in the towel. Well OK, maybe he was hoping for Black to blunder - it does happen. Snatched from the jaws of victory is White's hoped for outcome of continuation at this point. |
|
| Apr-17-18 | | Once: An interesting position. Winning the white queen isn't enough to guarantee the win. A pair of rooks plus one or more passed pawns can sometimes win or draw against a queen and rook. A lot depends on the quality of the pawns plus the relative king safety of each side. In this particular position, the white pawns are disconnected and not far enough up the board. The white king is far more exposed than the black king. Petrik makes it look easy, but a lesser player might struggle to contain those passed pawns. |
|
| Apr-17-18 | | sombreronegro: A loose queen with the king in the center of the board . Opportunities of skewers and pins. |

 | | Penguincw: I solved the Monday puzzle on Tuesday, now I'll try to solve the Tuesday puzzle, on Tuesday. Yep, I got it. 2/2 this week. Last few moves just pure technique. Queen vs. rook and pawn not the easiest to win, but black should prevail. |
|
| Apr-17-18 | | sombreronegro: Wow that was Caruana? A very young Caruana though which explains it. 16 Q X e5 seems a little off to me. x e 5 gives black a bad bishop and the two white bishops seems menacing and white could pawn storm king side. I might be missing a tactical problem but strategically white seems better with the pawn capture. |
|
| Apr-17-18 | | lzromeu: Why not Rb2??? |
|
| Apr-18-18 | | whiteshark: <CHC> I know. I was just kidding. ;) |

| Apr-18-18 | | sfm: <patzer2: White was busted after 30. R(a)d1? (should have played 30. Qe4 =), allowing 30...Rf4! -+. By the time it came around to move 34, White had no chance...>
Aha! Cute little threat with 35.-,Re2+, there is no satisfactory parade. <whiteshark: Is that the same Fabiano Caruana who'll fight for the crown in November? Tell me that is not the case...> As it turns out 34.Rd5 might be the best move!, retaining a fighting chance. |
