  offramp: Miagmasuren is probably the best ever player from Mongolia.
Jul-17-04  kevin86: Zugzwang!!! Black must move his king to allow white's entrance into c7. OR Black can temporize with the rook along the eighth rank-but white pushes b5-then captures at c6 or advances to c6 if black captures-----and queens soonest.
Jul-17-04  apple head: no its not a zugzwang if its whites move just b5 and its 1-0, and if black tryes stalling with his rook b5 and its lost
Jul-17-04  Dudley: This position was so blocked up that 54.Rxc6 was about the only possible move, but it gets harder after that. How about 54... Rb8 55.b5 cb 56.c6+ Ke7 57.c7 and it's over for black.

  Sneaky: This whole game is an amazing strategic conception. First Myag dominates the d-file while Black helplessly thrashes around behind his pawns. Then he slowly manuveurs his king into the pocket on the queenside, he liquidates the queens, he makes threat with his rook--and then BAMM!! he sacrifices the rook, forcing Black to give up his own rook and face a losing pawn ending. Beautiful!
Jul-17-04  Akavall: This game was played in the former Yugoslavia, I hope Miagmasuren doesn't have to fight of any charges. :)
Jul-17-04  misguidedaggression: Yes that was a nice tactic with the rook, but it was easy to see, this should have been a monday problem, not a sunday one. I got it in half a second! (ewww, I'm starting to sound like Ferocious Beast. :P ) Seriously though, 54.Rxc6 should be a hard move to find, but it just sort of jumps out at you and almost looks obvious.
Jul-17-04  misguidedaggression: err, um, that's right, it's saturday, isn't it? It's been a long day. :P
Jul-17-04  midknightblue: for me, it was hard to see this move. My move would have been Rh7+. It is not as good, but that is all i saw.
Jul-17-04  cjhasbrouck: 58. b5 xb5
59. c6+ Kd6
60. c7 Yz
61. b8=Q Rxb8
62. xb8=Q 1-0

I'm very proud of myself for understanding all of this. I think I'm making progress. :)

Btw, is there any common notation for "any move"? I like to use Yz (variables).

If there isn't any already, I think everybody should start using Yz.

Jul-17-04  bob725: Your pawn and king are next to each other and are almost at the 8th rank. The black king is too far way to do much.
Rook x pawn c6 is the logical move.

6/6 a great week so far.

Jul-17-04  macphearsome: Yeah, this seemed really easy for a saturday puzzle. I got it in two seconds, and I'm usually stumped by tuesday's puzzle... still, I feel that these chess puzzles (and the great environment and people here) are really improving my game.

  cu8sfan: I scored pretty well this week, even late like today. Must be summer and everything's shifting down a gear.
Jul-17-04  chesssloveeeer: 54.Rb8 55.Rb7+ 55.Kd8 56.Rxb7 56.Rxb7 57.Kxa6 won for white
Jul-17-04  karelen: pretty easy for a saturday problem.. but then again, we know there is game clinching move =)
Jul-17-04  rochade18: Finding the winning move was easy but calculating the continuation without moving the pieces is hard!
Jul-17-04  fred lennox: The control of the d file was decisive for white since the black king could not get to the queenside. Maybe 22...Bf6 is better than...Bf8 to protect d8
Jul-17-04  ezumpf: Wouldn't 53.... Kd7 have prevented this?
Jul-17-04  Calchexas: This was a very easy problem. Um, yeah, I saw Rxc6 practically immediately, but it was more difficult to work through the variations. That's probably the only reason this is a Saturday problem.

  Sneaky: I think this was a very difficult problem. I saw 54.Rxc6 instantly (after all, what other move could it possibly be?) but I didn't understand why it worked until I saw the game.
Jul-17-04  molinov: I think this should have been a Friday-Thursday problem.
Jul-17-04  weirdoid: wonder wthigow myagmarsuren after 1991 or so - is he still alive? also, IIRC back in early '80s there was another Mongolian player named something like Lhagsvaren who (as a junior) seemed pretty promising - anyone have any idea what happened with him afterward? Of course, seemingly very good juniors often never developed into great players for whatever reason (cases in point, Werner Hug and Mark Diesen), particularly considering back then it was so hard for anyone except WC-class talents to attain anything real before their mid-20's.
Mar-24-18  ChessHigherCat: I must be missing something because this seems suspiciously easy, especially after the killer Friday puzzle.

Checking the king doesn't do any good because black just interposes the rook, so it has to be Rxc6 bxc6. Now there's a choice between Kxa6 and b7, and the latter looks better because it prevents Rc8 to protect the c pawn. a5 isn't a threat because of the pawn on b4 and the king is too far away to prevent queening. Let's see what I'm missing.

Mar-24-18  Shamot: 54.Rxc6 does it very nicely. The moves after this are very logical and play themselves.

  al wazir: *Everyone* saw that the first move had to be 54. Rxc6.

Except that it didn't have to be.

After 54. Rh7+ K any 55. Rxb7, there's no way to prevent promotion. Black's goose is cooked, and so is the puzzle.
