| Feb-01-08 | | achieve: <DMBFan> Hits the nail on the head there re. practising the KNB v K mate for many reasons he mentioned... I've been spending a lot of time practising this myself the last few months, and one thing that strikes me (and I "invented" a term for it), which is: VISUAL (IN)DEPENDENCE
What I mean is, that Black clearly doesn't see the possibility of a mate procedure (less than 20 moves) along the SIDE of the board (position after move 105) - i.e. forcing the lone King from h3 to h8/g8 - the corner of doom in this case - but spends 10 moves neither improving nor worsening his position, and then sees the light and works the lone King towards a1 - along the first rank... What I encountered is the fact that it is very valuable, indeed necessary, to feel comfortable with BOTH colours and in all corners and along all 4 sides of the board-- in order to produce this procedure swiftly and decisively... With myself I noticed a definite VISUAL DEPENDENCE during the first week of practising it. |

 | | SteinitzLives: Key to this ending is not only mating in the corner that is the same color as the bishop but also:
1) Get the opposition whenever possible until the lone K is on the rim.
2) Create an "L" shaped wall with the N and B either with one square in between them on rank or file, or diagonally next to eachother.
3) Keep the N and B out of the Kings' way (without giving up key squares) when your K must move side ways in relation to the lone K!
4) A big part of doing this right is not being afraid to let the lone K off the rim once you have him in the mate quadrant of the board; don't worry, the K, B and N with the right one or two square-controlling moves will put the lone K right back on the rim, and on the rim square where you need him to be.
5) Remember the piece to-search-for-a-move priority: a) look for best K moves first, b) look for best N moves second, and c) look for best B moves last.
6) Practice using Pandolfinis' endgame book where he has several mate in 2, 3, 4 and more problems, with K+B+N vs. lone K, then you can keep "goal positions" that have such forced mates following them, etched in your mind. 7) One of the best descriptions of this mate process comes from Paul Keres' old book "Practical Chess Endings" (a book title shared by several other authors and books BTW). Keres gives an absolute worst case scenario in this ending and shows you how to do it with clear descriptions. |

 | | An Englishman: Good Evening: White's Ba1 looked as if it might as well have come off the board and left Black with an extra piece. On move 31, it did. White deserves a lot of credit for hanging on as long as he did. |

| Oct-11-22 | | goodevans: <perfidious: ... In either case, of course, this pun would not then have come to be.> I may be showing my ignorance here but could someone please enlighten me as to the significance of the '135' in the pun. To be honest I'm not even sure whether 'Shahade' is standing in for the Arabic 'Shahada' or for the phrase 'the Shade' and in neither case does importance of the '135' leap out at me. Maybe I'm barking up the wrong tree entirely? |

 | | Teyss: <goodevans> Was wondering the same, the only reference I could find was the world record temperature 134 F (in Death Valley for info), close enough, of course in the shade as all measurements go. https://en.wikipedia.org/wiki/Highe... Playing through that game there, don't know what would have melted first, the brain or the pieces. |

On another note, Black's somewhat sloppy in the endgame, up to a point where I believe Shahade didn't really know the B+N specifics but got there by playing logical moves. The main portion is at 110...:

And the White king is confined in the h8 corner. 110....Bg5 is fine, not great, but after 111.Kh2 Black should swap to the full W-manouver on the h-file with 111....Be3 112.Kh3 Bg1, which he doesn't. Black achieves the W-start at move 117, messes it up again straight after, achieves it again on move 121. At this point we're 24 moves in and Black's on DTM 32 so it's getting close (move 40). However, now it's White turn to choose the 'simple' defense 123.Kf1? which definitely throws the draw. Up to move 126 plays itself, Bf2 is a bit inefficient but not terribly, on move 131 it's #5 with 16 moves to go. Knowing the basic principles in the endgame helps to not waste too many moves, but especially do not let the king escape. The key line in this particular example would be 123.Kd1 Ke3 124.Kc2 Nd2 125.Kc3 Bd6:

 | | offramp: The pun is very funny; it is based on the hilarious comedy film called <37°2 le matin>. For chess players the optimum temperature for experiencing an ovulation is 135°F. In Europe we do not use Fahrenheit. |

| | Teyss: <TheaN> Thanks for this insight. B+N is a tricky endgame, some GMs even flunk it: R Kempinski vs Epishin, 2001 There are 26 games in the database ending with a draw vs 201 ending with a win: Endgame Explorer: BN vs K, Endgame Explorer: BN vs K |

| Oct-11-22 | | Granny O Doul: If people actually say "135 in the shade", it's a new development, though possibly justified by global warming. Relatedly, I'm struck by how often I still hear people willing to wager "dollars to doughnuts". Perhaps they're looking for suckers. When I want the flavor of the old expression, I offer Euros to Oreos. |
