May-25-19		al wazir: I got 19...Nxf2 20. Kxf2 fxg3+, but I wanted to played 21...g2 right away. After 22. Rg1 Qxh2 23. Nf3 Bg3+ it comes to much the same thing.

May-25-19		olinart: Got it, at least up to move 27 where white took a different tack. NxF2 is needed to open lines for the Black Q, and Black has rooks in place to exploit the open king side.

May-25-19		Cybe: 17. Nfg5? 17. N:d6 leeds to draw.

May-25-19		goodevans: I went with <19...Ne3+>. If <20.fxe3> then + 21.Kh3 Qh5+ 22.Kg2 f3+ 23.Kf1 dxe3> gives black a winning position. Better though is <20.Kg1>. Now <20...Qxe2> looks strong but what I failed to see was that white can thwart black's attack with <21.Nxd6 cxd6> (forced else 22.Ndf7+ mates) <22.Nf7+ Rxf7 23.Qxf7 Rg8 24.Qxf4>.

May-25-19		goodevans: Actually there is a way to make <19...Ne3+> work. After <20.Kg1> you sac the exchange with <20...Rxe4> before playing <21...Qxe2>. That avoids the nasty check on f7 and gives black a strong attack.

May-25-19		patzer2: In today's Saturday (19...?) puzzle, the weak position of the White King begs for a demolition sacrifice leading to mate. Stockfish 10 indicates three combination (i.e. sham) sacrifices (19...Rxe4, 19...Ne3+ and 19...Nf2+) are clearly decisive: ( [Stockfish 10 64] 34:-9.98 19...Rxe4 20.Nxe4 Ne3+ 21.Kg1 Qxe2 22.Qe6 Nd1 23.Rxd1 Qxd1+ 24.Kg2 f3+ 25.Kh3 Qxh1 26.b6 axb6 27.Nxd6 cxd6 28.Kg4 Qxh2 29.Qe7 Rg8 30.Kxf3 Qh1+ 31.Kg4 h5+ 32.Kg5 Qf3 33.Qd7 Qxf2 34.Qxd6 Ra8 35.Kg6 Qe2 36.Qd5 Qe8+ 37.Qf7 Qxf7+ 38.Kxf7 Rxa2 39.Kg6 Rg2 40.Kf5 Rxg3 41.Ke4 Rg4+ 42.Kf3 Kh7 43.Kf2 ) ( [Stockfish 10 64] 33:-8.75 19...Nxf2 20.Kxf2 fxg3+ 21.Ke1 Bf4 22.Qd5 Bxc1 23.Nf7+ Qxf7 24.Qxf7 Rxf7 25.hxg3 Ref8 26.a4 Be3 27.Nd2 Bf2+ 28.Kd1 Bxg3 29.Kc2 Rf2 30.Kd1 Kg8 31.Nb3 Bd6 32.Rh5 R2f5 33.Rxf5 Rxf5 34.Nxd4 Rf1+ 35.Kc2 Ra1 36.Nf5 Rxa4 37.Nxd6 cxd6 38.Kb3 Ra5 39.Kb4 ) ( [Stockfish 10 64] 33:-8.67 19...Ne3+ 20.fxe3 Qxe2+ 21.Kh3 Qh5+ 22.Kg2 f3+ 23.Kg1 dxe3 24.Qd1 Rxe4 25.Nxe4 Qh3 26.Qf1 f2+ 27.Nxf2 exf2+ 28.Qxf2 Rxf2 29.Kxf2 Qf5+ 30.Ke2 Qe5+ 31.Kf3 Qd5+ 32.Kg4 g6 33.Kh3 Qe6+ 34.Kg2 Qxa2+ 35.Kh3 Qe6+ 36.Kg2 Qd5+ 37.Kh3 Qf5+ 38.Kg2 Qxd3 39.Rce1 Qd5+ 40.Kh3 Qxb5 41.Rhf1 h5 42.Rf3 g5 43.Rfe3 Kg7 44.Kg2 g4 45.Re7+ Bxe7 46.Rxe7+ Kg6 ) My pick was 19...Ne3+ -+. P.S. So where did White go wrong? Stockfish 10 indicates the decisive error was 17. Nfg5, allowing 17...Bxg2 18. Kxg2 Ng4! -+ (-3.57 @ 29 ply). Instead, Stockfish 10 recommends complicating with 17. Qc4 fxg3 ∓ (-1.59 @ 34 ply). However, 17. Qc4 is a computer move that is difficult to see over the board and even with best play may not assure White's survival. For an earlier improvement, instead of 11. Rac1 f4! ⩱ to ∓ (-0.69 @ 28 ply, Stockfish 10), White can counter Black's flank attack and maintain a positional advantage by taking action to stengthen the Queen-side and the center with 11. b5 Nb8 12. e3 ⩲ (+0.76 @ 30 ply, Stockfish 10).

May-25-19		agb2002: Black has a bishop for a knight. White is about to play Nf3, closing the f-file and the diagonal d1-h5. Black has Ne3+ and Nxf2, the latter looking somewhat simpler: 19... Nxf2 20.Kxf2 (20.Nxf2 Qxg5 with the double threat fxg3 and Rxe2; 20.Nxh7 Nxe4 21.Nxf8 Qxe2+ 22.Kh3 Nf2+ 23.Kg2 f3+ 24.Kg1 Nh3#) 20... fxg3+ 21.Ke1 (21.Kg1 gxh2+ and mate in two; 21.Kg2 gxh2, with the threat Qg4+, looks winning) 21... Rxe4 (due to an eventual Nf7+) 22.Nxe4 (22.dxe4 Qxg5 followed by g2) 22... g2 23.Rg1 Qxh2 seems to win at least two pawns.

May-25-19		King.Arthur.Brazil: I agree that this is not a usual position and it is not easy to find the best move. I didn't succeed because I looked for a sacrifice like 19...Rxe4 which seems incorrect. Following the game, after 21.Ke1, I supposed g2 directly. It seems a little early, I saw that after 23. Rg1 the move Bxg5? is bad because of 24. Rxg5 Qh4+ 25. Rg3 Qxh2 26. R3g2 and all is over. Anyway, I didn't like Qxh2 because 24.Nf3 seemed to defend everything. Once more, the 24.Bg3+ is fundamental (hard to see it, at move 19...) Rxf3 therefore, it was expected! 26...Re3 (other simply and strong move). Although after 28. Rf7 I was tempted for the combination 28... R3xe4 29.dxe4 Bf2, with the threat of 30... Qc3#. But afterwards I saw that white can play 29.Rf3 and 29...Rxe2+? is impossible because of 30.QxRe2 and black cannot move Rxe2?? due to 31.Rf8#. I didn't see a victory comming soon. However, white position is almost lost but the only move he still had was 29.Qb3! (best that 29.Rf3 which lost immediately Qxa2+ ,30.Kxe2 Qxc2#). Including that if 29... Rxe4?! 30. Rxg2... The black will win (yes) but it is not so clear yet. That is my point.

May-25-19		OhioChessFan: <KAB> I went with 19...Rxe4 also and think that wins. 20. Nxe4 Ne3+ opens everything up and I don't see White holding. Say 21. Kg1 Qe2 and I think it's clear White won't survive.

May-25-19		RandomVisitor: After 6...0-0 white plays 7.Qb3 which is followed by 7...Kh8. The queen stay on b3 until after move 19, when the game is effectively over. Can white play a better move?
