Sep-06-21		Brenin: White is in danger of losing a R, so 35 Rxf7+ Qxf7 (otherwise 36 Rxd7) 36 Rf6 c6 (36 ... Rh7 37 Qxh7) 37 e6 Qxf6+ 38 Qxf6+ Kg8 (38 ... Ke8 39 Qxh8+) 39 e7 Ra8 (otherwise 40 e8=Q+) 40 Qg6 mate. A more subtle winning move is 35 Rgg6.

Sep-06-21		Cheapo by the Dozen: The first two moves are obvious. But then in both the game line and especially the 36 ... Qxf6 defense, more calculation is needed than is common for a Monday. That said, over the board I'd have done what I did in the puzzle too, which is play the first two moves and see how the position looked then.

Sep-06-21		Cheapo by the Dozen: Yah know -- "over the board" is an odd phrase. I may never play over the board again. I don't even own a modern clock. It's quite possible that I'll only play online.

Sep-06-21		agb2002: Black threatens Qxe6. White can trade the rooks for the queen and a pawn and then attack the black king with the queen and the e-pawns, 35.Rxf7+ Qxf7 36.Rf6 c6 (36... Rh7 37.Qxh7 wins) 37.e6 Qxf6+ 38.Qxf6+ Kg8 (38... Ke8 39.Qxh8+ Ke7 40.Qg7+ Kxe6 41.Qxa7 is a carnage) 39.e7 Rxe7 (39... Kh7 40.Qf7#; 39... Ra8 40.Qg6#) 40.Qxe7 wins.

Sep-06-21		drollere: this is a grinder: 35. Rxf7+ Qxf7, 36. Rf6 and the Q dies.

Sep-06-21		saturn2: Both white rooks are attacked. 35.Rf6 was my move to get out of this. I looked at the answers 35...c6 36.e6, 35...Qxf5 36.Rgxf7 35...Qxd3 36.Rfxf7 all losing for black

Sep-06-21		Tomate: After 35.Rxf7+ Qxf7 36.Rf6 it seems that Black will get 2 rooks for the queen + Pawn, which is material equality. I believe the analysis should go further. Indeed White will win another rook or will checkmate. The variants are A) 36..Qxf6 37.Qxf6+ Kg8 38.e6 (with the threat 39.Qf7#) Rh7 39.e7 (with the threat 39.Qf8#) Ra8 40.Qe6+ followed by e8=Q, winning a rook B) 36..Rh7 37.Qd8+ Ke7 (37..Kg7 is similar) 38.Rxf7+ Kxf7 (again 38..Rxf7 is similar) 39.Qb8! winning the Ra7 C) 36..c6 37.e6 Qxf6+ 38.Qxf6+ Kg8 39.e7 Ra8 40.Qg6# or 39..Kh7 40.Qf7#

Sep-06-21		Teyss: A bit tricky for a Monday because you have to see the two main defences 36...c6 and Qxf6 and the fact that with an even material (Q+P vs 2Rs) White wins thanks to his advanced P (granted only in a few moves). Revealingly our stars <Brenin> and <agb2002> did not look at the line 36...Qxf6 37.Qxf6+ (exf6 also wins) Kg8 (else 38.Qxh8) 38.e6 and Black will have to give up a R for the eP, e.g. 38...Ra8 39.e7 Rh7 (...Re8?? 40.Qg6# or ...Kh7?? 40.Qf7#) 40.Qe6+ K moves 41.e8=Q

Sep-06-21		Teyss: <Tomate> We posted at the same time. In your line 36...Rh7, 37.Qxh7 is simplest (the BQ is pinned). But then I also missed a move: in my line 38...Ra8??, 39.Qf7#

Sep-06-21		tivrfoa: The black pieces are too far to protect. The question is, is black already toasted after: 31.Rf6 ?

Sep-06-21		chrisowen: Its flowers d'echecs no daunt no?

Sep-06-21		chrisowen: Fence no it off like no?

Sep-06-21		TheaN: White wins by means of e5, making this is a bit trickier than a regular Monday as others have stated; and you start to look for something else which doesn't exist. <35.Rxf7+! Qxf7 (Kg8 36.Qg6#) 36.Rf6> now both seventh rank defenses lose swiftly, 36....Rh7 37.Qxh7 +- is fastest, but on both Rh7 and c6, 37.e6! +- is curtains because Black is forced to take on f6 after which e6 runs. <36....Qxf6+ 37.Qxf6+ Kg8 (Ke8 38.Qxh8+) 38.e6 +-> and Black's helpless against the combined ideas of Qf7# and e7 with Qg6/Qf8/e8.

Sep-06-21		landshark: 35.Rxf7 Qxf7 36.Rf6 .... If B defends the Q with ....Rh7, simply QxR because the Q is pinned by the R on f6 which is supported by the pawn on e5. Or.... 36....Qxf6 37.exf6 (!) threatening Qc8+ winning the h8 R and virtually anything B does can be met by e5 and e6 with a crushing duo of passed pawns on the 6th which will win. This is more nuanced than the "typical Monday" - - let's see if I missed a more "Monday - ish" solution.

Sep-06-21		Teyss: <tivrfoa: The question is, is black already toasted after: 31.Rf6 ?> Fair question, I didn't have time to look at the rest of the game this morning but now I do. Actually yes after 31.Rf6! White wins. Of course 31...gxf6? is a disaster: 32.exf6 (threatening Rg7+ and Qxh6#) ...Rg8 33.Rxg8 Kxg8 34.Qxh6 and mate. So 31...Rh8 is more or less forced to protect h6 in the future, White captures the B (32...fxe6? 33.Qg6+ and mate) and despite being a P down his position is overwhelming. Which means 3 things: (a) It's a interesting weekend puzzle on move 31. Why weekend? Because you have to see the combination until the end with the sacs 31.Rf6!, 34.Rxg7+! and 35.Rxf7+! BTW Black could accept the second sac with 34...Kxg7 but after 35.Rg6+! fxg6 36.Qxd7+, White will push the eP as in the game. (b) Instead of 30...Rxa7? Black could have won with almost any other move keeping the a8 R on the last rank: there is no rush to take the N. If now 31.Rf6? gxf6 32.exf6 Rg8 33.Rxg8 Rxg8 wins. One idea is to play 30...Qe8 to protect g8 and only now play ...Rxa7. Black will be a N up with a passed P on the Qside and a solid position. (c) White was lucky but also smart: if 30.Rf6? immediately instead of Kh2, ...gxf6 31.exf6 Qa1+ 32.Kh2 Qxf6 wins. Probably was hoping for 30...Rxa7 and breathed a sigh of relief when Black didn't play 30...Qe8. Hence regardless of mistakes on both side (White getting his N trapped, Black not defending correctly) it's a beautiful combination starting on move 31.

Sep-06-21		Jimfromprovidence: I didn't see the text move 36...c6 but like many others I saw 36...Qxf6. Don't think it matters much if 37 Qxf6+ or 37 exf6, below follows. click for larger view <landshark> mentioned the threat of 38 Qc8+. There is also 38 Qxc5+ as well, so the king has to move. So if black follows with 37...Kf7, then white has 38 Qxc5. click for larger view Notice that black cannot move his a rook because of 39 Qe7+ so he loses it here.

Sep-06-21		gawain: I could see nothing better then trading the two rooks for Black's queen and pawn, with a seemingly winning position. Then I realized that in fact there is nothing better than that.

Sep-06-21		Honey Blend: The winning continuation after 36. ... ♕xf6 37. ♕xf6+ ♔g8 seems to be 38. ♕d8+ ♔g7 39. ♕e7+ ♔g8 40. e6 click for larger view Black is doomed.

Sep-07-21		Tomate: @Teyss Right! In line B, 37.Qxh7 is simplest and best.

Sep-08-21		master8ch: 34.Qf6 Rh7 35.Re7 Qxe7 36.Qxe7 Ra8 37.e6 also looks very strong.

Sep-09-21		tivrfoa: <Teyss: <tivrfoa: The question is, is black already toasted after: 31.Rf6 ?> Fair question, I didn't have time to look at the rest of the game this morning but now I do. Actually yes after 31.Rf6! White wins.> Thanks a lot @Teyss for your great analyses!
