 SHOULD I play this out ... ?! My suggestions are my opinion, and I welcome others to give theirs. I am sure many will be different. Anyway, mine will generally have substantial technical difficulties in winning or require precise technique. An example of the latter being "Q+K vs R+K" and also N&B Mate. I would not mind playing those out from the strong side and could use the practice! It is not out of line to ask another player to "prove" their technique imo. |

Even vs Expert+ opponents ... Some others *** Q+P endings unless there is a distant passed pawn against you, or more than one healthy extra pawn elsewhere. *** Down a piece in the opening or early middlegame, but with initiative ... especially if you have any compensation in the form of extra pawns or substantial development, or space & mobility in your field of attack vs cramped opponent. Re the latter, especially if you have there a localized preponderance of attackers in that area. If Attackers exceed Defenders in number by just ONE, in a field of play, then theory says it is a potential sac situation ... However, their King always counts as a Defender and yours does not count as an Attacker. Also if the position is just so complex that "everything is hanging", for everyone. That was always my own favorite. *** Mentioned R vs Q. Therefore also R+P(s) vs Q. And look to make something called a "Fortress". Also play Rook + Minor piece vs Q, or Two Minor pieces vs Q especially 2 Knights. *** Minor Piece vs Rook when pawns are equal on same side of board. It is quite often drawn. *** Thats all I have in mind at the moment. Probably more from me later. What do you think? Also let me know if anyone disagrees. And your additions too! Thx ~! |

It Depends ... Down a couple of pawns with the attack ... stay on track Mate in sight ... give it up, it's alright One pawn down against a King ... you loose, just ain't your thing A Rook behind ... you're in a bind Craig, I'm sorry, never fear ... late at night with too much beer Dragon (I'll hate myself in the morning) |

Lasker... Several of the positions suggested by baronderkilt (Hi Craig) are 'book wins' but that require skill or rote learning to realise the win. Cases in point are the K+B+N vs K and K+Q vs K+R endgames. In my view they are worth playing out if only for the sake of instruction. I'd even play out a K+Q vs K+N endgame, because they can be very tricky. I probably wouldn't play out a K vs 2B endgame, but it might depend on my opponent's rating (and I think this is fair enough). There are other positions that might or might not be winning (or drawing). The Rook and minor piece endings (with pawns) is always a tricky one. In the following position reached after White's 21st I (Black) battled nearly 40 moves for the win: Gameknot, 2005 b Was White correct to play on? Of course he was - and in fact had a forced draw for the taking at one point. Even after then, the issue might well have been in doubt in his view (it wasn't in mine, that I admit that was just a strong 'gut' feeling). Further, it took me quite a while to hit on a plan, and when I did, it involved allowing White a mobile Q-side majority. So White stood to win if my judgment had proved faulty - a risk I was prepared to take. Other positions are just plain obscure. It is well known that R+P vs B is very hard to win if the pawn happens to be a knight-pawn (i.e. a b-pawn or g-pawn). I found this out when I got this in a pick-up game against a well-known NZ master-level player and couldn't find the win. In a R+2P vs B+N ending a couple of years back, I had to reckon my opponent giving up a N for P to arrive at such an ending. Fortunately I was able to ascertain that I could win it; and White didn't try that line anyhow. And then there are the 'book' draws - ones in which the material advantage isn't suffiecient to win. Well, that's as maybe. Right now I have 2 Rook and pawn endings in which I have the pawn minus Can I hold either of them? I don't know, for sure. The only way to find out is to play on. Cheers, Ion. |

Thanks Ion ... *** R vs R+N. Very difficult to be won in 50 moves unless the position happens to be right for it. I once drew it vs a strong Master *** Also as Fischer has proven, these positions will actually Draw if the defending King is in front of the pawns and the Rook correctly placed ... R vs R + a&h pawns R vs R + d&f pawns or c&e pawns **** And defender's King in front of pawns, Rook to side with distance; although it is considered a Win it is difficult & requires knowing the correct idea, when the game is of: R vs R + a&b or g&h pawns (I once won one vs an FM, but was somewhat fortunate in that, as I did not really know how as an Expert at the time, until After the game. Tho of course we must Never admit it; there IS luck in Chess **** R vs R + P is almost always Drawn if the defending King is in front, and sometimes even when cut off from contact with the pawn but only by only 1 file ***** So there are some more that I would play out vs just about anyone |

bhidragon ... I've been trying to think of a catchy tune to hum your post to (and anyone who knows me, knows I actually have been) and could not get one. Its not your fault, the advice sounds great. Unfortunately, I am having a dry-spell . . . };-D |

LOL Maybe a little early Eminem free rap or North Shore hip-hop band Ill Valley? I don't know if it'll get done with the classics ... Stones, Zeppelin or Bach ... take your pick. Do you play chess differently depending on what music you're listening to? I never thought about it. How would that work? Dragon |

I think if a player acheives that position against a player of your ability, then it's fair to assume they'll finish you off. I can win with ease with 2xB vs K. But I do see your point, I think I'd resign against a 1600+ player, but maybe not lower. I just wonder how often you'll find yourself with just a king against two bishops against a 1500 player. I'll resign if I feel I can't win or draw, it's that simple for me. I'll never continue in a hopeless position, it's demoralising. |
