|Mar-14-16|| ||stacase: <Cheapo>
What year was that?
|Mar-14-16|| ||Cheapo by the Dozen: <stacase>,
1973 or so. I was born 1/1/60. I scaled back on playing tournaments in academic years 1972-3 and 1973-4, and stopped completely after that.
So this was long after Fischer was that young, a while after Larry Christiansen was that young, and well before various waves of immigrants -- Polgars et al. -- and so on.
|Mar-14-16|| ||dfcx: Of course white wins by
As <Phony Benoni> said, Kxg7 leads to mate.
I hate Mondays without mates, so played further,
A. 45...Kd7 46.Qf5+ Kc7 (the other moves loses faster) 47.Be5+ Kb6 48.Rb1+ and mates in 3.

B. 45...Ke6 46.Bh3#
|Mar-14-16|| ||lost in space: I love Mondays, with or without mate or queen sacs.
44. Bg7+ and whatever black does there is a big material plus afterwards and it seems that mater is near...for example
44. Bg7+ Kxg7 45. f8Q+ ... or
44. Bg7+ Ke7 45. f8Q+...
|Mar-14-16|| ||psionl0: What? No Q-sac? It CAN'T be Monday!|
|Mar-14-16|| ||stst: B-sac for this Monday
Completely visual - errors may creep in....
44.Bg7+ KxB (forced)
|Mar-14-16|| ||agb2002: White has a rook and a pawn for the queen.
Black threatens Bxf7, Bd7, Bd4, etc.
The black king stops 44.f8=Q. Hence, 44.Bg7+:
A) 44... Kxg7 45.f8=Q+ Kg6 46.Qf6+ Kh5 47.Bf3#.
B) 44... Ke7 45.f8=Q+ + - [R]. A curious mate: 45... Ke6 46.Bh3#.
|Mar-14-16|| ||The Kings Domain: Didn't get this (heh). One of those simply deceptive typa puzzles. Good one.|
|Mar-14-16|| ||The Kings Domain: Cute and charming game. While Spraggett is no Kasparov, he played a pretty impressive game and little Zhansaya certainly learned a few important lessons from it.|
|Mar-14-16|| ||saturn2: Bg7 and the king has to give up the blocking square for the queening pawn.|
|Mar-14-16|| ||whiteshark: Well, it's Monday and I've been here before... ;)|
|Mar-14-16|| ||morfishine: <44.Bg7+> Nice finish|
|Mar-14-16|| ||zb2cr: No Queen sacrifice this Monday. 44. Bg7+ chases Black's King off of f8, allowing White to Queen. |
If 44. ... Ke7; 45. f8=Q+, White is up by a full Rook and should win easily.
If 44. ... Kxg7; 45. f8=Q+, Kg6 White is only up by the exchange, but will mate after a short King hunt, as <Phony Benoni> illustrates.
|Mar-14-16|| ||patzer2: For today's Monday puzzle (44. ?), we find a great investment opportunity.|
We give up a Bishop worth three points with 44. Bg7+, and after 44...Kxg7 45. f8(Q)+ we triple our investment with the promotion of a pawn to a Queen worth nine points.
Black's decisive mistake appears to be 35...Rd2?, which allows 36. Qxd2! (+1.72 @ 24 depth, Deep Fritz 15).
Instead, the computers indicate 35...exf4 = (0.25 @ 23 depth, Deep Fritz 13) holds it about level.
|Mar-14-16|| ||perfidious: <patzer2....We give up a Bishop worth three points with 44. Bg7+, and after 44...Kxg7 45. f8(Q)+ we triple our investment with the promotion of a pawn to a Queen worth nine points.>|
Have always welcomed a 300 per cent ROI; in my line, I would settle for grinding out a whale of a lot lower percentage than that over time.
|Mar-14-16|| ||kevin86: I saw this one, but I thought I missed it! The bishop sac vacates the queen square so that the pawn can promote ; white will be a rook ahead (no mate or queen sac this Monday)|
|Mar-14-16|| ||Chess Dad: Good Monday puzzle.
The principle of the deflection sacrifice is definitely something that I need to cover with my son. This is a great puzzle to show that.
|Mar-14-16|| ||YetAnotherAmateur: I completely agree with <Phony Benoni> when it comes to finding mate after the initial combination. There are definitely wins after 44. Bg7+ Ke7 45. f8=Q+|
For example, this blunder:
45. ... Ke6? 46. Bh3#
Or this sequence:
45. ... Kd7 46. Bh3+ Kd8 47. Bf6+ Kc7 48. Be5+ wins the queen.
|Mar-14-16|| ||patzer2: <perfidious> Going back one move earlier to 43. f7! (diagram below),|

one could argue White earns only a 12.5% ROI (i.e. 9-8/8 = 1/8 = 12.5%) after giving up a Rook and a Bishop (worth 8 points) to promote a Queen (worth 9 points) with 43...Qxb8 44. Bg7+ Kxg7 45. f8(Q)+.
However since it's mate-in-two after 45...Kg6 46. Qf6+ Kh5 47. Bf3+#, it's clear White's gain is far more than an extra point after 43. f7! .
|Mar-14-16|| ||gawain: Nice puzzle, Mondayish in two ways: there were very few candidate moves, and we did not have to look very deep to see that one of these moves is a definite winner.|
|Mar-14-16|| ||dark.horse: Monday, and there's no Q to sac?!? Well, we'll make one!|

Thanks <Chris>,but I still dont know who the driver was ?
|Mar-14-16|| ||CHESSTTCAMPS: I like a Monday puzzle that breaks the usual pattern and adds some complexity. The blunder 44.fxe8+?? Kxe8 45.Re1 Qb3 costs white at least a half point. Instead, white can force mate with 44.Bg7+! Ke7 (Kxg7 45.f8=Q+ Kg6 46.Qf6+ Kh5 47.Bf3+) 45.f8=Q+ and now:|
A. 45... Ke6 46.Bh3#
B. 45... Kd8 46.Rd1+ Bd4 47.Bxd4 cxd4 (Qb3 48.Bf6+ Kc7/c8 49.Qxc5+ Kb8 50.Be5#) 48.Rxd4+ Kc7 49.Qd6+ Kc8 50.Qd8#
C. 45... Kd7 46.Bh3+ Kc6 47.Qf6+ Kb6/b7 48.Rb1+ with mate shortly.
|Mar-14-16|| ||Bubo bubo: 44.Bg7+ ensures promotion of the pawn. Black cannot afford to capture because of 44...Kxg7 45.f8Q+ Kg6 46.Qf6+ Kh5 47.Bf3#. But 44.Ke7 45.f8Q+ does not look much better, as Black is down a rook and will soon lose at least more material.|
|Mar-14-16|| ||paavoh: Bg7+ leading to pawn promotion and a simple win after Kxg7 and a slightly more complex after Ke7. Probably Black regretted not taking the draw by three-fold repetition at move 26.|
