 | | takchess: This Patzers ego is boosted. 8). Only 2 real candidate moves b sac and e3 push. The sac is clearly better and the combination plays itself |

| | takchess: Chess Author and trainer Neiman labels this type of combination as an Extraction. |

| May-26-18 | | malt: 22...B:f2+ 23.K:f2 Qb6+ 24.Re3
(24.K:g3 f4+ 25.K:g4 Bc8+ )
24...f4 is as far as I got |

 | | Richard Taylor: I solved this. I had to calculate exactly if say 24. Re3 then I thought (having eliminated a poss. Q sac on e3) f4 25. Ndf1 Nf5 26. Qe2 fxe3+ 27. Nxe3 Nxe3+ 28. Kg1 Ng4+ 29. Kh1 Nf2+ 30. Kg1 Nxh3+ 31. Kh1 Qg1# This was one of the lines I saw. But of course Black has a better position with the exchange up. Another was 24. Re3
f4 25. Ndf1 Nf5 26. Kg1 Nxe3 27. Nxe3 fxe3 28. Qe2 Rf2 29. Bxe3 Rxe2 30. Bxb6 Nb3 31. Bxb3 axb3 and so on. And say 24. Re3 f4 25. Nhf1 Nf5 26. Nb1 Nxe3 27. Nxe3 fxe3+ 28. Ke1 Rf2... But there were other lines. White clearly gets tied up and loses the exchange and the position. As Gawain's opponent played 24. Kxg3 and f4+ etc was easy to see it was mate with the Q coming back to d8. Although in my calculations I brought the B back to c8 also but that also wins...! |

| | Richard Taylor: <stacase: Now that was fun! Not often I get a Saturday puzzle move for move all the way to the checkmate. Hmmm, I think I've gotten every one this week so far.
<ChessHigherCat: This must be patzer ego-boosting week:> Yes indeed!>
Good on you. But if you want some really difficult ones...in fact there is a mix. Leonard Barden has a column I think it is in the Guardian. (He has games in there also. But in our local 'Listener' he just has a puzzle). Some are excruciatingly difficult. They are either from actual games as above, or from studies or problems or they are those self mates or reconstruction things. Some I see very quickly. Others I can spend a week on and still get nowhere. Or I get part of it. All good fun. Sometimes it is far from ego boosting though. Part of the problem is they vary randomly in difficulty. But he usually gives some kind of discussion leading up to them. He has been doing those at least since 1986 or so. Possibly earlier. |

| May-26-18 | | weary willy: <Ref Richard Taylor earlier> - Leonard Barden is a phenomenon - his column in the Standard is over 60 years old - don't know when it was first syndicated in your local newspaper. All British chess players should be grateful: Wikipedia states "... Chess columns:
As of 2010, his weekly columns have been published in The Guardian for 54 years and in The Financial Times for 35 years. A typical Barden column not only contains a readable tournament report, but is geared toward promoting the game. His London Evening Standard column, begun in summer 1956, is now the world's longest running daily chess column by the same author, breaking the previous record set by George Koltanowski in the San Francisco Chronicle. Koltanowski's column ran for 51 years, 9 months, and 18 days, including posthumous articles." |

| May-26-18 | | Carlos0012358: Horrible 24.Kxf3 (instead of Re3) turns a tough game into an instant looser. |
|
| May-26-18 | | stacase: <<Richard Taylor: <stacase ... >
Yes indeed!> Good on you.>
Thanks for the reply - what I really need is to play chess. Back in the '80s & '90s I played a daily noon game. Even a few touraments - my first game I won against a 1500 rated player (-: It was down hill from there though. I rarely play against a quality player now - never is probably more truthful. I look forward to tomorrow's offering. |

 | | Jimfromprovidence: It's interesting how the Stockfish output in the line 22...Bxf2+ 23.Kxf2 Qb6+ 24.Re3 prefers 24... Qd4, below, over 24...f4 by a couple of pawns at 26 ply.
click for larger viewNow white can't play 25 Ndf3 and it appears white has to spend a tempo moving the queen in order to activate that d2 knight. This enables black to follow with 25...f4. Finding 24...Qd4 ups the puzzle difficulty level a couple of notches. |
|
| May-26-18 | | Marmot PFL: The solution kind of jumps out at you 22...Bxf2+ 23 Kxf2 Qb6+ Now 24 Kg3 f4+ leads to a mating finish, 24 Re3 f4 25 Nf1 lets white survive longer. |
|
| May-26-18 | | Big Pawn: A pretty easy one for a Saturday! 22...Bxf2+ 23. Kxf2 Qb6+ 24. Kg3 f4+ 25. Kh4 Qd8+ and mates. |
|
| May-26-18 | | Reisswolf: As Gawain Jones demonstrates aptly here, sometimes it is better to give away a bishop than to accept one as a gift from the opponent. |

 | | gawain: Lovely king hunt by the real Gawain. Way to go! |
|
| May-26-18 | | messachess: Pretty easy if you see the Q check. (I didn't.) |
|
| May-26-18 | | Toribio3: I like this game. It reminds me of the great attacking player in the person of Mikhail Tal. |
|
| May-27-18 | | hdcc: I was first considering the pawn push (e3), and I then realised that the Bishop sac looked good. I figured out the first three moves and then played through to the solution, which was all very straightforward. My (rank patzer's) ego would have been boosted by how I went, too - except for the fact that my fourteen year old son, who doesn't play chess at all seriously, saw the Bishop sac first up in a matter of seconds... |

He also wrote or edited a book on Chess which came out in 1980 called 'Play Better Chess' which is still good with good photographs of famous players and opening and ending techniques. Also 'How to Play the Endgame in Chess' which is good. I haven't studied endings enough but I find them fascinating. He is good for chess indeed I think he was British Champion at least once. |

This year no tournaments or club but some internet games each day. I seem to either win a lot of win nothing. I know I start losing when I am tired so at 70 I am doing o.k. Chess is only a hobby though. But if you want to improve playing in tournaments, doing these kinds of problems and others; watching those videos as well as studying opening and other theory. My weak point is openings for higher level chess. I find it tedious to study openings. I do some but I prefer studying combinations, ending and tactics...mainly for interest. But to improve you also need to play regularly in tournaments etc When I was doing that I won some tournaments and improved my rating. |
