Nov-04-23		Brenin: Material is equal. White has Q and R en prise. She can sacrifice the R and use the Q to take Ps and expose the Black K: 22 Qxh7 Nxd1 23 Qxg6+ Kd8 24 Rxf8+ Bxf8 25 Bg5+ Kc7. I got that far, but didn't anticipate trapping the Q with 26 Qf7+ Bd7 27 b3, the point being that Black's LSB is now pinned, so 27 ... Qc5 loses to 28 Nxe6+. An amusing finish.

Nov-04-23		mel gibson: I wasn't sure. Stockfish 16 says: 22. Qxh7 (22. Qxh7 (Qh5xh7 Bc8-d7 Bd2-e3 O-O-O Qh7xe7 Rf8-e8 Qe7-d6 Nf2xd1 b2-b3 Qc4-c7 Qd6xa6+ Qc7-b7 Qa6xb7+ Kc8xb7 Rf1xd1 ) +6.37/45 271) score for White +6.37 depth 45.

Nov-04-23		scormus: Every move except 27 b3. Too fixated on the check sequence. But I like to think 27 Nxe6+ also wins

Nov-04-23		dannydoc: A nice feature this website should add for those of us who don’t have a chess engine, is someone at the end of each puzzle, when a side has resigned, should play out the game to show how and why the white or black side wins. To me it isn’t always obvious, and I have in some cases continued the analysis to show that a mate could have been avoided. I’m sure that I was wrong, not being a strong player myself.

Nov-04-23		mel gibson: <dannydoc: A nice feature this website should add ....> In this game Black's Queen is trapped so he resigns. It's easy to have your own engine. Just download the free Arena interface and the free Stockfish engine. When Black resigns Stockfish 16 says: 27. .. Qxe2 (Qc4xe2 Nd4xe2 Nd1-c3 Ne2-d4 Ra8-e8 Nd4xe6+ Re8xe6 Qf7xf8 d5-d4 Kc1-b2 Nc3-d1+ Kb2-b1 Nd1-c3+ Kb1-a1 Nc3-b5 Qf8xb4 d4-d3 c2xd3 Kc7-c8 h2-h4 Bd7-e8 Bg5-f4 Nb5-c7 g2-g4 Be8-b5 Qb4-e4 Bb5-c6 Qe4-f5 Bc6-d7 h4-h5 Re6-e8 e5-e6 Re8xe6 Qf5-c5 Re6-c6 Qc5-e5 Bd7-e8 h5-h6 Be8-g6 h6-h7 Bg6xh7 Qe5-h8+ Kc8-b7 Qh8xh7 a6-a5 Qh7-f5 Rc6-e6 Qf5-c5 Re6-e1+ Ka1-b2) -6.91/40 187 score for Black -6.91 depth 40.

Nov-04-23		NimzoCharlie: Where can I go to get instructions re how to use Arena and Stockfish once I have downloaded them? I have been playing since the ‘60’s, but I’ve never used an engine and would like to have that option.

Nov-04-23		Allderdice83: Dang! I had it all up until 27. b3!!. I saw a line where Black would play Bc5 and White would later play b3 trapping the queen. But I didn't see that here, 27 ... Qc5 28. Nxe6+ also wins the queen. I had 27. Nxe6+ which looks like it still wins. After 27 ... Kc6, White has a couple options. Either 28. N2d4+ Kb6 29. Qxd7 Nf2 30. Bd8+ Rxd8 31. Qxd8+ Kb7 32. Qxf8 Qf1+ 33. Kd2 Qd1+ 34. Ke3 Ng4+ 35. Kf4 -- this is a bit hairy, as White is almost mated, but not quite, while at the end White is threatening mate and is up a piece and 3 pawns. But it's less hairy than the other option. 28. Nxf8 Qxe2 29. Qxd7+ Kb6 30. Bd8+ Rxd8 31. Qxd8+ Ka7! (else White takes the d pawn with check and then the knight) 32. Qc7+ Ka8 33. Qc6+ Ka7 and White must play very carefully here, eg. 34. Qxd5?? Ne3! 35. Qc5+ Kb7 36. b3?? (loses, White must play for a perpetual check here starting with possibly 36. Qb4+) Qe1+ 37. Kb2 Nd1+ 38. Ka1 Nc3+ 39. Kb2 Qb1# 34. Nd7? looks good on the surface. It threatens 35. Qb6+ or 35. Qc7+ and 36. Qb8#. However, Black has 34 ... Qe3+!! and anything White does leads to a perpetual check, eg., 35. Kxd1 Qg1+ followed by 36 ... Qxg2+ and then 37 ... Qe4+ 35. Kb1 Nc3+! 36. bxc3 Qe1+ 37. Kb2 Qxc3+, etc. So the only winning line for White is 34. Qc5+! Kb8 35. Nd7+ Kb7 36. Qxd5+ Kc7 37. Qxd1 Qxd1+ 38. Kxd1 Kxd7, and White's up 4 pawns and wins easily.

Nov-05-23		scormus: <Allerdice83> Nice analysis, but not so sure about the <Dang!> I checked with SF which prefers our move, 27 Nxe6+. I can't say <choice>, since I didn't think of b3. Both are convincingly winning, but as you say, the win is very straightforward with the text move and I think the better choice OTB. In a pub game, Nxe6+ definitely. Things can go wrong after 27 Nxe6+ Kc6 28 N2d4+?! Kb6 29 Qxd7, when there is no handy follow-up check. In view of W's back rank vulnerability, 28 N6d4+ might be the wiser choice.
