I always read your posts closely :)

Jul-22-13  TheaN: Monday 22 July 2013

<48.?>

An incredibly easy puzzle even for a monday, cause this one doesn't even involve a slightly out of the box combo to win. White simply destroys the final obstruction on the h-file:

<48.Rxh7+ Kxh7 49.Rh6# 1-0> take note that even Qh2+ works, white's position is too strong.

Jul-22-13  TheaN: Typical how many solvers still associate the queen with a monday puzzle and go for 49.Qh2+.
Jul-22-13  nottogoodabeginner: Yes it is an easy puzzle to solve but the key is getting to this position in the first place. That's my problem.

  FSR: Monday already? 48.Rxh7+! Kxh7 49.Rh6#.
Jul-22-13  Bartimaeus: <TheaN : Typical how many solvers still associate the queen with a monday puzzle and go for 49.Qh2+.>

In this case, I think it has less to do with using a Queen for a Monday puzzle and more to do with what follows intuitively for the given position. In a mating attack, it seems a natural tendency to bring your most powerful piece into play (if available). At least in my case, the first instinct was to play Qh2+ after Kxh7 and i wasn't even thinking of using the Queen considering it to be a Monday puzzle.

Oddly enough, the fact that it was a Monday puzzle helped me to find the faster mate. When i saw that the Qh2+ line was leading to a mate in 4 moves, i felt a little suspicious and thought this to be a tad long for a Monday puzzle. I looked again and then found the shorter mate.

OTB, i would have gone for Qh2+ without any hesitation. No point in beating about the bush once you find a clear mating line.

Jul-22-13  Nick46: Got all the moves -> ridiculously easy -> wouldn't give a peanut for black's position. What day(s) the Qsac?
Jul-22-13  morfishine: FWIW: This game was from the under-12 division
Jul-22-13  whiteshark: <48. Rxh7+ Kxh7 49. Rh6#>, and that's it!
Jul-22-13  Lambda: Nothing wrong with Qh2+. When you've seen a forced mate, there's little point looking for a faster one.
Jul-22-13  awfulhangover: OMG, I belong to the Qh2 patzers.
Jul-22-13  YetAnotherAmateur: Drat, I also picked Qh2+, after seeing that black could only throw away his knight and queen to delay the inevitable.

But hey, at least it wasn't a queen sac Monday.

Jul-22-13  JustWoodshifting: Black may have remained in the game for a while, but for an inevitable loss:

47.Bg5 Nxf5 48.Bxe7 Rxe7 49.Qg5 Rxg6 50.Qxe7 Rg7 51.Qf8+ Rg8 52.Qh6 Rg7 53.f6 Nxf6 54.Qxf6 Rf7 55.Qxe5+ Kg8

And Black should capitulate.

  chrisowen: Hand he choosing maybe the quicker path to victory
bad for black no matter what before he goofed so,

which rook of course it is einger pinches oh low he,

take looparch 48.Rxh7+ king had to recapture when,

g6 it slide over providing 49.rh6+ be l0 win longer mind debatable 49.Qh2+ hug the rail gg over now nh5 at door 50.Qxh5+ going have light I clean send,

reinforcement up ahouse 50...Qh6 51.qxh6#.

Jul-22-13  kevin86: The one rook sacs,the second rook mates. Not only is there no queen sac,there is not even mention of a queen-the queen CAN mate,but it is a lesser move.
Jul-22-13  Alex56171: I love Sundays! 48. Rxh7+ Kxh7 49. Rh6#

  OhioChessFan: You are a lot better than me. You love Sundays and I miss Mondays, Qh2+, alas.

Interesting viewpoint. It dependent on what white sees in advance I guess. The Bg5 has only vacanced h6 a move ago, so I guess it's kind of counterintuitive to see Rh6. The 'advantage' is that both lines work here, rather than just the mate in two.

Anyway, it's funny how black's worst enemies are his own pieces.

Jul-22-13  Doniez: But after Qxh7 and Kxh7, it's still the same ending, Rh6# or am I missing something?
Jul-22-13  YouRang: <Doniez> The only point is that white would *have* to find Rh6# because the less-pretty Qh2+ (and subsequent mate) would not be an option.
Jul-22-13  Doniez: Ok, thanks...
Jul-22-13  BOSTER: <YouRang: It would have been slightly better had it been>.

This is the pos. after 40...Bxg5 ,white to play.

Jul-23-13  eblunt: How about 42.Rxh7+ Kxh7 43 Bf6 any 44 Qh6 mate

Quicker than Qh2 !

Jul-23-13  eblunt: Oooops, apart from the fact it doeant work, forgot the king had moved and the Bish doesn't pin the Knight. Hmmmm back to drawing board.
