Sep-19-16		Phony Benoni: Ok, I see wha happened. Previously, the puzzle started at White's 18th move. That is harder. This is Monday level.

Sep-19-16		lost in space: I love Mondays! 21. Nxd5+ cxd5 (else: Nxc7 and the queen is gone) 22. Qxc7 Rxc7 23. Rxc7 Nf6 24. Rxb7 1:0

Sep-19-16		zb2cr: 21. Nxd5+ wins material. The Queen is forked, so 21. ... cxd5 is in order. That is met by 22. Qxc7, Rxc7; 23. Rxc7. White is now up by the exchange and a Pawn, with a pin on the Black Bishop at d7. Black can protect the Bishop with 23. ... Nf6 (or 23. ... Rd8). White can then snap off another Pawn on b7 while maintaining the pin.

Sep-19-16		dfcx: No mate for today. 21.Nxd5+ cxd5 (or loses queen) 22. Qxc7 Rxc7 23.Rxc7 white is up an exchange with 2R+N against R+B+N, also winning another pawn after black moves next to protect the bishop.

Sep-19-16		Steve.Patzer: That was way too easy.

Sep-19-16		patzer2: Black's final decisive mistake was 17...Be7? allowing 18. Bxh7 (+3.30 @ 19 depth). Instead of 17...Be7? 18. Bxh7 , developing with 17...0-0 18. Bxh7 Nxh7 18. f5 (+1.03 @ 20 depth, Deep Fritz 15) keeps Black in the fight. Earlier, instead of the odd 11...Ng4 12. h3 (0.63 @ 20 depth, Deep Fritz 15), Black can equalize with 11...h6 12. Rfc1 = (0.06 @ 22 depth, Deep Fritz 15). Today's Monday puzzle solution 21. Nxd5+! exploiting a pin with a Knight Fork is a continuation of the combination begin three moves prior with 18. Bxh7 . P.S.: This game illustrates why moving pieces more than once in the opening is not a good idea.

Sep-19-16		agb2002: White has a knight for a bishop. White can take advantage of the knight fork on d5 to win the exchange and a couple of pawns: 21.Nxd5+ cxd5 (else 22.Nxc7) 22.Qxc7 Rxc7 23.Rxc7 Nf6 24.Rxb7, etc.

Sep-19-16		saturn2: White gives the knight and gets rook and pawn.

Sep-19-16		AlicesKnight: 21.Nxd5+ should gain enough; 21....cxd5 (or the Q goes); 22.Qxc7, Rxc7; 23.Rxc7 gains the exchange and White can force a further reduction in material to make the R tell. 19....Bxh4 should short-circuit it though after 20.fxe6 Black must not allow the g6 fork.

Sep-19-16		AlicesKnight: I now see that there is earlier posting doubting the value of 19....Bxf4 because of Qg6 possibilities. Maybe....

Sep-19-16		YouRang: How nice! I can just refer to my post from 10 1/2 years ago! 21.Nxd5+ still wins the same way.

Sep-19-16		WorstPlayerEver: There's something wrong with this site; I am still logged in. I'm trapped lol can't log out.

Sep-19-16		leRevenant: <Steve.Patzer: That was way too easy.> For a Monday? You must surely be joking.

Sep-19-16		et1: ok but this is not a Monday...

Sep-19-16		patzer2: <AlicesKnight> If 19...Bxf4, Deep Fritz 15 indicates White wins with 20. Qxf5 when play might continue 20...O-O (20... Bxh4 21. Nxd5 cxd5 22. Qxc8+ Qxc8 23. Rxc8+ Bd8 24. Rxf7 +10.34 @ 21 depth ) 21. Nxd5 cxd5 22. Rxc7 (perhaps even stronger is the computer choice 22. Bxe7 Qxc1 23. Rxc1 Rxc1+ 24. Kh2 Rc7 25. Bd6 Rfc8 26. Nxf7 h5 27. Nh6+ gxh6 +9.22 @ 20 depth) 22... Rxc7 23. Bg3 Bd6 24. Qf3 Re8 25. Qxd5 (+7.79 @ 20 depth).

Sep-19-16		drleper: <WorstPlayerEver: There's something wrong with this site; I am still logged in. I'm trapped lol can't log out.> You can logout, but you can never leave.

Sep-19-16		Cheapo by the Dozen: Not as huge a win as we expect on Mondays, but White can quickly exchange down to rook vs. knight (with no other pieces on the board) and a 2 pawn advantage. That's pretty solid.

Sep-19-16		PawnSac: < drleper: <WorstPlayerEver: There's something wrong with this site; I am still logged in. I'm trapped lol can't log out.> You can logout, but you can never leave. > LMAO Yes, he's a prisoner of his own device!

Sep-19-16		PawnSac: Well WPE, at least you can sit down, pour a glass of wine and relax to some good music.. Hotel California / Eagles 1977 https://www.youtube.com/watch?v=mhY...

Sep-19-16		kevin86: White forks king and queen and then gains a rook with a battering queen.

Sep-19-16		RandomVisitor: Quoting myself from 10 1/2 years ago: <By the way, I'm no expert here. I'm just running Rybka on the position and posting what it sees.> It took me 9 1/2 years to switch to another engine... After 16.Nxe6! white would have won earlier. click for larger view Komodo-10.1-64bit: +2.32/37 16...Nxe6 17.Bxf6 gxf6 18.Nxd5 Qd8 19.Bf5 Kf8 20.Kh1 Rb8 21.Nc3 Ng7 22.d5 Qe7 23.dxc6 bxc6 24.Be4 f5 25.Bxf5 Qxe3 26.Be4 Rd8 27.Rcd1 Qc5 28.a3 Nh5 29.Rf3 a5 30.Qa4 Be7 31.Rxd8+ Bxd8 32.Bxc6 Rg8 33.Ne2 Kg7 34.Kh2 Nf6 35.Rc3 Qb6 36.Rg3+ Kh8 37.Qc2 Rxg3 38.Nxg3 Qc7 39.Nf5 +2.82/37 16...fxe6 17.f5 e5 18.Bxf6 gxf6 19.Nxd5 Qg7 20.dxe5 Bxe5 21.Nf4 Qe7 22.Rfd1 Rd8 23.Be2 Rd6 24.Qa4 a6 25.Nd5 Qg7 26.Nb6 Rxd1+ 27.Rxd1 h5 28.Nc4 Qc7 29.Qb4 Nd7 30.Nd6+ Bxd6 31.Rxd6 Kd8 32.Bc4 a5 33.Qd2 Rh7 34.Be6 Kc8 35.Qd4 h4 36.a3 a4 37.Kf2 b5 38.Kf1 Re7 39.Kg1 Rh7 40.Kf2 Re7 41.Kf1 Rh7 42.Kg1 Re7

Sep-19-16		MaczynskiPratten: It's great to see the evidence to remind us of the long-service medals of <RandomVisitor>, <YouRang>, <patzer2>, <al wazir> and <kevin86> in the earlier kibitzing, and of course <Phony Benoni> with his equally long-standing puzzle compilations. Take a bow, guys! Apologies to any other faithful long-standing posters I've missed.

Sep-19-16		Herma48852: 21. Nxd5 cxd5 22. Qxc7 Rxc7 23. Rxc7

Sep-19-16		steinitzfan: I am slowly making peace with the new wave of Monday puzzles. This one shows a simple case where two tactical ideas are blended -- a fork and line clearance (or is that diversion?) Anyway, it's more than one.
