Sep-04-07		AlfieNoakes: Pretty mate puzzle from 32 ? White to move.

Sep-04-07		AlfieNoakes: If 33 KxN then 34 Qh7+ Kf8 35 g7+! and black is in 2 queen trouble

Apr-15-22		Brenin: Unlike Westerinen, my idea was to trap Black's Q with an immediate 15 g4, e.g. 15 ... Nxg4 16 Ng3, or 15 ... Qg6 16 Bd3. I think this also works, winning the Q for a couple of pieces. Rather obvious for a Friday?

Apr-15-22		al wazir: <Brenin: Unlike Westerinen, my idea was to trap Black's Q with an immediate 15 g4, e.g. 15 ... Nxg4 16 Ng3>. That doesn't trap the ♕: 16...Qg6 17. Bd3 (17. Nh4 Bxh4) Qe6. Now what?

Apr-15-22		raymondhow: I chose the immediate 15.Ng3 which the engine says is not as good as 15.g4, but leads to a greater advantage than the game move. Think I deserve half credit.

Apr-15-22		An Englishman: Good Evening: <raymondhow> can claim full credit, in my humble opinion.

Apr-15-22		Granny O Doul: Pretty hard to resist g4, I'd have thought.

Apr-15-22		geeker: Agreed, I'd have played 15. g4 and was surprised to see a different game continuation.

Apr-15-22		raymondhow: Why thank you < Englishman >, but I'm not sure I would have found the right line after that one move.

Apr-15-22		mel gibson: I chose 15. Ng3 This is a game where there are multiple good solutions. The question is - how many good solutions? I will cover 3 of them here. Stockfish 14 chooses a different move saying: 15. g4 (15. g4 (g2-g4 ♕h5-g6 ♗c4-d3 ♘h6-g8 ♘e4-f6 ♘c7-e6 ♗d3xg6 ♘e6xf4 ♘f6xg8 ♖f8xg8 ♕e2-h2 ♘f4xg6 h3-h4 h7-h6 e5-e6 d7xe6 h4-h5 ♘g6-h4 ♘f3xh4 ♗e7xh4 ♕h2xh4 f7-f6 ♕h4-g3 c6-c5 ♕g3-c7 c5xd4 c3xd4 e6-e5 d4xe5 f6xe5 ♖h1-h4 ♗c8-e6 ♕c7xb7 ♗e6xa2 ♕b7-a6 ♗a2-d5 ♖e1xe5 ♖g8-d8 ♕a6-a4 ♗d5-f3 g4-g5 h6xg5 ♖e5xg5 ♖d8-d2 h5-h6 ♖d2xb2 ♖g5xg7) +6.61/35 185) score for White +6.61 depth 35 Forcing Stockfish 14 to follow the game line: 15.

Apr-15-22		Whitehat1963: Amazing finish!

Apr-15-22		Brenin: <al wazir: That doesn't trap the ♕: 16...Qg6 17. Bd3 (17. Nh4 Bxh4) Qe6. Now what?> True, it doesn't trap Black's Q (I assume that <w> was a typo) but 18 Neg5 Bxg5 19 Nxg5 Qxa2 (Qd5 20 Be4) 20 Nxh7 Re8 21 Bxh6 gxh6 22 Nf6 looks devastating, with Black's K wide open to attack.

Apr-15-22		Stanco: 14.g4 traps the Lily 14... Nxg4 15.Ng3 or 14...Qg6 15.Bd3 Qe6 16.Ng5 Bxg5 17.Nxg5 Qa2 18.Nxh7 etc...

Apr-15-22		agb2002: The knight on c7 is defenseless and the black queen lacks mobility. This suggests g4, Bd3 and Ng3. In the case of 15.Ng3 Qg6 16.Bd3 Qe6 17.Bxh6: A) 17... Qxh6 18.Nf5 Qe6 19.d5 cxd5 (or 19... Nxd5) 20.N3d4 wins the bishop on e7. B) 17... gxh6 18.Nf5 looks good for White. ----- In the case of 15.g4 Qg6 (15... Nxg4 16.Ng3 wins decisive material) 16.e6 Nxe6 17.Ne5 traps the queen but the cost is surely too high: 17... Nxf4 18.Nxg6+ fxg6 19.Qd2 d5. Instead of 16.e6 White can play 16.Bd3 Qe6 (16... f5 17.exf6 gxf6 [17... Bxf6 18.Nd6 wins the queen] 18.Nd6 wins decisive material) 17.Neg5 Bxg5 18.Nxg5 Qxa2 19.Nxh7, with the double threat Nxf8 and Bxh6, must be winning. ----- In the case of 15.Bd3: A) 15... f5 16.exf6, with the double threat Bxc7 and fxe7, wins decisive material (16... Nd5 17.fxe7 Nx4 18.exf8=Q+). B) 15... Nd5 16.Ng3 Nxf4 17.Qd2 Nxd3 18.Nxh5 Nxe1 19.Kxe1 wins decisive material. C) 15... Ne6 16.Ng3 as above. D) 15... Qg6 16.Nf6 Nf5 17.g4 D.1) 17... gxf6 18.Bxf5 Qg8 (18... Qg7 19.exf6 Bxf6 20.Bxc7 wins a piece) 19.exf6 Bd8 20.Bh6 wins decisive material. D.2) 17... Bxf6 18.Bxf5 wins the queen. D.3) 17... Nd5 18.Nxd5 followed by Bxf5 wins a piece. D.4) 17... Ne6 18.Bxf2 Nxf4 19.Qd2 Qh6 20.g5 traps the queen. ----- I'd play 15.Bd3.

Apr-15-22		Hercdon: So full credit for g4, correct?

Apr-15-22		TheaN: Yeah botched this one up, wanted to play the much more flashy 15.Nf6 which frankly still gives White an edge. Partially to blame is that I couldn't finish a dead won game yesterday and chickened out with a perpetual instead; so I rushed this a bit. Played against a former club champion that I have a rather bad record against so was happy with the draw. Nothing as hard as winning a won game, right... :>

Apr-15-22		henilsson: Chrisowen and z free: it is a pity that your understanding of english so limited.

Apr-15-22		whiteshark: I've calculated everything up2#.

Apr-15-22		Stanco: henilsson in the lack of ants is is fine, no?

Apr-15-22		scormus: How nice and simple it would be if getting the best first move was sufficient. I fancied 15 g4, which SF rates as best, but had a different and evidently sub-optimal defence by B, namely ... Nxg4 (16 Ng3 Qg6 17 Bd3 Qd6 18 hxg4 then perhaps ... Qxg4 19 Rxh7+ Kg8 20 Nf5)

Apr-16-22		al wazir: <Brenin: <16...Qg6 17. Bd3 (17. Nh4 Bxh4) Qe6. Now what?> True, it doesn't trap Black's Q (I assume that <w> was a typo) but 18 Neg5 ...> In my line that isn't a possible move.
