|Feb-07-11|| ||1.e4effort: this seems cut and dried:
21. K whatever...Rxh1
and White should resign if he hasn't already
|Feb-07-11|| ||Patriot: <knight knight> <It's worth checking the black rook can't be trapped (or kept out of play). White's first move needs to be 22. Qb5 (otherwise 22...Rb8 and the other rook can connect on b1) but black simply replies 22...Rxh4 and the rook escapes via h5. If white's h-pawn was instead on h3 black would have a hard time getting the rook back into play.>|
I think you make a good point about Qb5 and keeping the other rook out of play. Even if the h-pawn were on h3, it's all a question of technique. I can see white winning a7, e7 and d6. For example starting with 22...Rc8 23.Qb7 Rc5 24.Qxe7. I think white can then play 24...Rb5 (not 24...Ra5?? 25.Qd8+ and 26.Qxa5).
This might be a good position to play against a computer for practicing technique.

Your friendly local Crafty End Game Trainer is happy to defend the position colours reversed (White to play and win). Link:
I won first time but it was much harder work than I expected - I had to disgorge my N to break a blockade and then had to think hard before I could safely transpose to a won K&P ending forty or fifty moves later. Enjoy finding a speedier win!
<MiCrooks: Actually I think this is an interesting puzzle for a Monday.> I agree. <But I would like to see most patzers win this against a GM. As an exercise they could try it against a computer.> Easier to win against a GM than a computer. The only way it could arise would be in a simul - whereupon the GM gracefully resigns!
<scormus> thanks for the link to M Stean vs E Ungureanu, 1976 (I added http:// to get the link you had intended).
<Phony Benoni: <MiCrooks> Good point. I feel uneasy about puzzles like this for the same reason. It's very easy to get into the mindset of thinking an "easily won" position will play itself, then very hard to get back to figuring out the moves yourself when something goes wrong.
As a practical matter, I don't think it would help White to try and play on a piece down (20.Kd1 Rxb2 21.Rxb2 Qxb2 22.Rh3 or 22.Kd2), simply because I think most
people would feel more comfortable playing with a simple extra piece than an unusual grouping like RRN vs Q>. I was delighted when the EGT decided to go for that ending - the fewer pieces the EGT has the fewer opportunities it has to swindle me (or should that be for me to swinsle myself?). My best strategy is to simplify against it, handing back the odd Pawn to get something clearcut which preserves an advantage.
I take risks against humans, not against computers. Playing the EGT I rearely look for mating combinations (except of course in POTD puzzle positions) - I trust it to avoid them. Playing a human it is a different matter. "Trust the opponent" works well against computers but not against humans - for an example where the great Tal gets it wrong see Lutikov vs Tal, 1955.
|Feb-07-11|| ||benjinathan: I saw it, but would I have played it?
I think so because the 2 rooks should make short work of white's pawns if nothing else.
|Feb-07-11|| ||LoveThatJoker: <gmalino: Ok,
is really silly because of
and the opportunity has gone.
gmalino, it would be wrong to play 19...Rb5 in the first place because it would allow 20. Qxb5! when Black is a Rook down.
It is worth considering such a move because it does have the potential to trap a major piece or, at the least, divert the major piece's attention from an attacking post; but such moves must be checked carefully, lest it gives the opposing side a splendid tactical resource.
|Feb-07-11|| ||kevin86: Black sacs the queen-but picks up both rooks and a knight in return.|
RR+N vs Q is such a big advantage that they can win even WITHOUT pawns.
|Feb-07-11|| ||YetAnotherAmateur: 19. ... Qxc3 is great. I'm not so keen on the bxc3 response though - it seems like white could have better damage control by conceding the knight and refusing the sac with Kd1 or Ke2.|
|Feb-07-11|| ||Brandon plays: RRN vs. Q. Yeah, I'll take that trade. Qxc3|
|Feb-07-11|| ||M.Hassan: "Very Easy" Black to move 19...?
A Knight and two Rooks for a Queen?
|Feb-07-11|| ||Marmot PFL: The idea of most Monday puzzles is to get less experienced players used to the idea of giving up the queen, something many won't do even for mate.|
|Feb-07-11|| ||cuppajoe: My thought process (typical of Mondays):
"I don't understand, it's Monday, but White doesn't have anything at all after Qxf6.
Oh, it's Black to play."
|Feb-07-11|| ||VincentL: "Very Easy".
19.....Qxc3+ wins 2 rooks and a knight for the queen, or just the knight if white declines
After 20. bxc3 Rxb1+ 21. K moves Rxh1.
I am guessing that white resigned straight away. Letīs check.
|Feb-07-11|| ||scormus: <David2009, added http://> thanks, this is one of my all time favorite games. If I remember right B players had enjoyed a lot of success in the early 1970s with this line of the Najdorf-Polu.|

I agree, wouldn't want to play against Houdini with black. Been there done that.

Interestingly first class dismantle, aged sic. but instructive it was. Dont forget to castle crusty white.
|Feb-07-11|| ||Phony Benoni: One reason I feel many players would have trouble winning this ending is that it requires coordination between the pieces rather than just a one-on-one brute force approach. Such coordination is very difficult to learn, and not a major part of the amateur's toolbox.|
