Mar-05-24		takebackok: After 32...Rxg2+ white is fully cooked.

Mar-05-24		Mayankk: Black is up a Bishop but may have King safety issues with his King in the firing line of White Knight and Queen. It was easy to see that Black can force a swap of Rooks to make its material superiority count via 32 ... Rxg2+ 33 Kxg2 Qe2+ 34 Kh3 (34 Qf2 Qxd1 is worse) Qxd1. But what next? Does White have any tactical sequence up its sleeve via the many discovered checks it may try. 35 Nxh7+ Kg7 doesn't work, neither does 35 Ne4+ Ke5. 35 Nf3+ is equally bad if not worse. So, seems like our forced Rook swap works. Not a flashy result but effective nonetheless.

Mar-05-24		King.Arthur.Brazil: One plausible line is: 32...Rxg2+ 33. Kxg2 Qe2+ (34. Kg1 Qxd1+ 35. Kg2 Qe2+ 36. Kg1 Kf5) 34. Kh3 Qxd1 35. Ne4+ Ke5 36. Nxd6 Qxd6 37. Qg5+ Ke4 38. Qg2+ Ke5 39. Qe2+ Ne4...

Mar-05-24		mel gibson: I saw the first ply straight away. It's not a fast checkmate. Stockfish 16 says: 32. .. Rxg2+ (32. .. Rxg2+ (1. ... Rxg2+ 2.Kxg2 Qe2+ 3.Kg1 Qxd1+ 4.Kg2 Qe2+ 5.Kg1 Kf5 6.Qf2 Qxf2+ 7.Kxf2 Kxg5 8.Kg2 Kf5 9.Kf3 Bc7 10.a6 bxa6 11.c4 a5 12.Ke2 Ke4 13.Kd2 f3 14.h4 Bf4+ 15.Ke1 a4 16.Kd1 Kd3 17.Ke1 Bg3+ 18.Kd1 Nb3 19.c5 f2 20.c6 f1R+) +M20/53 256) Black wins_ mate in 20. When White resigns: 35. .. Ke5 36. Ng3 (1.Ng3 fxg3 2.Qd4+ Qxd4 3.cxd4+ Kxd4 4.hxg3 Ke3 5.Kg2 Nd3 6.g4 b5 7.axb6 axb6 8.Kg1 Kf3 9.Kf1 b5 10.Kg1 b4 11.Kf1 b3 12.Kg1 b2 13.Kf1 b1Q+) -M13/55 50 Black wins _ mate in 13.

Mar-05-24		An Englishman: Good Evening: Simple, but notable--double checks rarely have so little effectiveness.

Mar-05-24		saturn2: 32. Rxg2 and black gets back the rook. If white declines it by 33.Kh1 black has Rxg5 or even Re2 should be enough. His king is not really in danger.

Mar-05-24		jffun1958: 36. Nf2 is mate in 5: 36...Qf3+ 37.Qg3 fxg3 38.Ng4+ Kf4 39.Nf6 g2+ 40.Kh4 g5#

Mar-05-24		TheaN: Tad bit sloppy on this one, first I was looking for White, but then <32....Rxg2+ 33.Kxg2 (else Rxg5 -+) Qe2+ 34.Kh3> if Qf2 first Qg4+! with Qxd1+ -+, or else Qxd1+ straight away. But after Kh3 I thought 34....Qe3+?! would trap the White king beautifully after 35.Kg4? h5+ -+, however, besides simply going back to g2 White also has 35.Nf3+!, it still loses after Kg7 but Black makes it a bit harder. Instead <34....Qxd1 35.Ne4+ Ke5 -+> simply avoids all checks and keeps an additional piece to boot.

Mar-05-24		ferrabraz: I also considered the cynical 32...Kf5

Mar-05-24		sfm: "It's the Kirill, Stupak!"

Mar-05-24		chrisowen: If pay its bun v rod an its work its q Rxg2 its a bud axled its ie arrived its odd go Rxg2 its ear;

Mar-05-24		sfm: Smart play by White, and he had 17.Nd4!! +5.68 Alas, such is chess (and life and football etc...)

Mar-05-24		dheilke: I don't like puzzles like this that have multiple solutions. I saw the line with 32...Rxg2+ (but didn't see the Ke5 follow up) - but I didn't like the risk... Ultimately, if I had faced this position in a real game, I would have just played 32...Kg7, which SF16 gives a -7 score (i.e. totally winning) - so one might say the 32...Kg7 is a winning solution (though not the "book" solution)

Mar-05-24		King.Arthur.Brazil: Dear <dheilke>, forgive to disappoint you but after <32... Kg7?> 33. Qxh7+ Kf6 (33... Kf8?? 34. Qh8#) 34. Qh4, back where we started, so if you insists again 34... Kg7, game is tied by repeating moves. So, Kg7 is a weak move.
