| Apr-17-06 | | notyetagm: Black forces mate with a very nice <Greco mate>, 25 ♘xd6?? ♕xh2+! 26 ♔xh2 ♖h5#. The <Greco mate> has got to be one of the most often overlooked mates. I once watched a strong amateur on ICC play a blitz match with a computer: he lost twice in five games to simple Greco mates! Speaking of ICC and <Greco mates>, here is a nice one that I played the other day on ICC in a bullet (60 seconds) game:

|
| Apr-17-06 | | mr j: easy peasy :) |
|
| Apr-17-06 | | unclewalter: <An Englishman>, good puzzle for the evening after easter, eh? |
|
| Apr-17-06 | | dzechiel: Easy, even by Monday standards. Took me one second to spot the bishop on a7 and a half second for the combination. I've gotten this style mate off several times in the last couple of years. Sometimes you have to provoke the advance of the f-pawn in order to check with the bishop and drive the king into the corner. |
|
| Apr-17-06 | | cuendillar: An textbook puzzle. It displays a tactical idea in a clean way without other distractions. This one's very easy if you're familiar with the idea, otherwise much harder. That's probably the deeper point with Monday puzzles - to train pattern recognition. |

| Apr-17-06 | | itz2000: 0 seconds? never been that easy.. :S |
|
| Apr-17-06 | | dakgootje: One of the puzzles where you often see it purely on intuition. Didnt notice the bishop on a7 until i checked whether my Qxh2 was right. not because i looked for the most obvious sac, but just because i saw the puzzle and even before i looked at where all the pieces where i thought the move, but of course, if you trust too much on intuition you miss a lot of counter-moves so you do have to calculate a little after it. ps: As i wasnt able to look at this site yesterday, just a quick question: was it a hard puzzle, or just like the others previous week, relatively easy for a sunday? |
|
| Apr-17-06 | | Chunkey Monkey: I was looking for the white move for a while...cough cough. The art of attack in chess by Vukovic deals with all these rudimentary mating patterns and Nunn has computer evaluated the oversights in pre-Fritz analysis but I find it an enjoyable read. Just bought Larsen's games and really nice and purchased after reading an interview with Aroninan where he said he studied Larsens's games a lot. How do you save games on ICC by the way? The ratings seem very inflated? |

 | | OBIT: It's easy to criticize 25. Nxd6, but the only move to try to stop the mate without losing material is 25. h3; however, then 25...Rg3 (threatening 26...Bxh3!) wins. I'd pin the loss on 24. b3?? - it was imperative for White to move the rook off f1 so that he could play Nf1. |
|
| Apr-17-06 | | dakgootje: < It's easy to criticize 25. Nxd6, but the only move to try to stop the mate without losing material is 25. h3> Yes thats probably true, i looked for a while at 25. d4, so the a7 g2-diagonal was temporairly blokked, but of course that doesnt work for too long either... What about 24. Nb3 preparing the same d4 for blokking the diagonal, but now with an extra defence for d4, so i think it will hold longer. |

| Apr-17-06 | | EmperorAtahualpa: Yep! Got it! 3 seconds or so.. |

|
| Apr-17-06 | | cuendillar: What about 25.Rf2 as a last resort? White gets some control over the dark squares for the exchange and blocks immediate mate threats (I think). Black is certainly better, but there are practical difficulties in converting it, while d4 and h3 allows a straightforward attacking idea as far as I can see. |
|
| Apr-17-06 | | Halldor: Nearly instantly - before I had located all the pieces - and then the longest time (a fraction of a second) to go along the diagonal and find the bishop. <notyetagm> Very good example of the <Greco mate>, thanks! |
