You got me....good one. Ill keep working on it.
Heres the solution I came up with to the problem I posted.
QXD5....white must then take with Bishop or move QE4, or QF3 to block an immediate checkmate.
IF BXD5...then black moves bishop D5
If Qf4/QE4, then black takes with queen. White bishop must respond with BXFE4/F3.....
Black then takes with Bishop f4 or e3........checkmate with rook h1.
If white BXD5, then black BXD5.....checkmate can be delayed by moving queen F4 or E3.
Makes sense? I hope there aren't any errors but let me know.

Your idea is ok, but it's not a mate in four, sorry.
Bishop can go to H6, for example.
But this is not a problem. This is simply a position,
a "combination." Real problems have to follow the
guidelines for problems, namely economy (nothing on the
board that does not serve a purpose), etc. True, some people
will prefer these kinds of positional studies, and
there's nothing wrong with them, but they're not
problems in the classical definition. Fischer's little
book is a series of positional studies with mating
outcomes, and those can be fun, can test one's ability...

Sent an email with a guess about Pat's last problem.
These are very hard for me. I've never played chess, though more than it took to learn the piece-rules (I never quite figured out "en passant", castling, etc.). Embarking on a regular game of chess always felt like being at sea without a map. But this seems much better---it's only a pond.

Hey guys,
Still around. :) Just a little preoccupied lately and haven't had a chance to look at the new problem. Hopefully later tonight. Any solutions yet?

I've received a couple of right answers on this last one.
The question always remains, if the variations are seen
as well, those variations that follow. Sometimes we guess
but don't know what really goes on... I trust you, though...
Here's what is called a "miniature."
Seven pieces at most.
White pieces:
bishops at d6 and g4
rook at c3
king at g3
black pieces:
pawns at d2 and e2
king at d1
White to move and mate in two
(about a one minute problem, maybe two)
and here is another cute little thing:
White pieces:
pawns at a6 and e6
knight at d5
rook at h6
queen at h8
king at g6
Black pieces:
pawns at b5, c6, e7, f6
knight at a7
bishop c8
rook at a8
king at b8
white to move and mate in two
(about a two minute problem)

Finally, here is an end-game study:
White pieces:
rooks at c2 and e2
king at h3
black pieces:
pawns at a3, b2, d4
bishop c3
knight f1
king g1
White to move and draw. Black is way ahead in material,
in that he is about to promote a pawn to a queen. White
must pull off a little miracle.

I guess people are done with the chess for now...
Surprising how little interest there was.

I'm not saying anything against anyone, especially those
who took an interest. I just thought there were more
chess enthusiasts among the climbers.
del, your answer for the miniature isn't right. Isn't
even a piece on the square of the piece you say moves...

I very much appreciate the thought & effort behind these. Thanks! I'll work on the newest ones when I get a chance & have a board (physical or virtual) to move pieces around on.

Today's LA Times:
At age 10, chess master is already an old pro
Sam Sevian holds the title of youngest U.S. chess master — for now. The average age of chess masters has been steadily falling for years, but recently, that pace has quickened.
By Scott Kraft, Los Angeles Times
May 5, 2011
Reporting from Santa Clara, Calif. -- The two chess masters hunched over their royal armies, lost in thought.
On one side, playing white, was 10-year-old Sam Sevian, who a few months ago became the youngest chess master in the history of the U.S. Chess Federation.
His opponent, playing black, was David Adelberg, 14, who had been crowned Arizona's youngest chess master when he was 12.
Sam had lost a match to David two years earlier. This time, he vowed, would be different.
The windowless hotel meeting room in Agoura Hills, filled with dozens of players, was as silent as a church sanctuary.
Sam and David came out playing the Scheveningen variation of the Sicilian defense, a favorite of the grandmaster Garry Kasparov, one of their idols.
As the match entered its fourth hour, Sam decided to stir things up. For 40 minutes, he studied his position, brown sneakers suspended above the carpet, fists pressed against his chestnut-colored hair, lips moving silently.
Finally, Sam made his move: a bishop sacrifice.
Sam's father, Armen, smelling of the cigarette he'd smoked on the balcony, caught his son's eye with an expression that silently asked: How's it going? Sam shrugged his shoulders and raised his palms: Who knows?
But Sam's chess coach, standing nearby, watched with a small smile of satisfaction. "What he's doing is very complicated, very complicated," he said. "But it might work."

The title of chess master is awarded to players who reach a threshold of points, earned in official tournament competition and based on their performance as well as the strength of their opponents.
The average age of chess masters has been steadily falling for years, but recently, that pace has quickened. To win a tournament in Reno last year, Jesse Kraai, a 28-year-old grandmaster from the Bay Area, played four of his six matches against children; the average age was 13.
"Today, you have 7- and 8-year-olds who are training better than Bobby Fischer did a generation before," said David Pruess, content manager for chess.com, a global chess website with 3 million members. He holds the international master ranking, one step higher than master and one below grandmaster.
This bounty of prodigal talent has had an unintended side effect: The half-life of a newly minted chess star has shrunk "to a year or two, tops," said Pruess, 29. "It's easy for a kid on his way up, full of confidence bordering on arrogance, to forget that he's become a target for even younger players."
Pruess, in a column last year, detailed his own loss to David Adelberg and good-naturedly warned the youngster that he'd better start preparing "for the 10-year-olds who will soon be coming to get him!"
That was prescient. Young David's nemesis turned out to be Sam Sevian, a fourth-grader from Santa Clara who, in December, became a chess master at the age of 9 years, 11 months and 11 days.
(Sam followed in the footsteps of Fischer, who earned the title of youngest chess master in 1956, at the age of 13 years, 3 months and 29 days.)
Sam is the pre-pubescent embodiment of the single-minded passion for chess that H.G. Wells once described as "a desire that dieth not, and a fire that is not quenched."
He lives with his obsession, and his parents and younger sister, in a modest two-bedroom condominium near San Jose International Airport.
A professional chess board sits on the coffee table in the small living room; chess books, in English and Russian, are stacked on the side tables.
Sam and Isabelle, 8, share a bedroom with three single beds; one is for their grandmother, who often visits from Armenia.
He keeps his favorite inspirational reading material on the bedside table: the fantasy adventure series "Percy Jackson & the Olympians," which features a 12-year-old demigod on a journey to prevent apocalyptic wars between three Greek gods.
In some ways, Sam is a typical kid. He rides his bike inside the gated condo complex and watches television when his parents allow it. ("Two and a Half Men" is a favorite).
Most afternoons, though, are devoted to homework and chess. "I never get tired of playing chess," he said, "but I do get tired of studying it."
One afternoon before his rematch with David, Sam arrived home from school and immediately went into his parents' bedroom, where he sat down at the family computer. He logged onto a chess website, looking to challenge someone to a game of blitz chess.
In an official chess match, each player is allowed a set number of hours to make all his moves and six-hour games are not uncommon.
In blitz chess, each player gets three to five minutes. Blitz chess games aren't official, but many players use them to hone their skills.
A 57-year-old international master from Serbia accepted Sam's invitation.
Swiftly moving the pieces with his computer mouse, Sam finished off his opponent like an afternoon snack. "That felt good," he said.
Later, Sam logged onto a laptop on the kitchen table for a lesson, over Skype, with his coach, Andranik Matikozyan, 32, an international master who lives in Los Angeles.
They practiced opening moves and went over exercises to prepare for the tournament.
Sam's father, Armen, 39, is a physicist with a doctorate from the University of North Carolina who works at a Silicon Valley company that makes lasers.
He grew up in Armenia, where chess is a closely followed sport, and was himself a strong player as a youngster.
Not so long ago, Sam and his father would spend evenings playing chess. No more.
"I don't want to waste his time," Armen Sevian said with a laugh.
Sam was born in New York, and the family followed his father's job changes to Florida, Los Angeles and, three years ago, to Santa Clara.
When Sam was 5, his father introduced him to the game.
"Most kids just move the pieces quickly," Sevian said. "But Sam really studied the board. From the first moment I watched him play, I thought, 'there you go.' "
When Sam was 7, and playing a tournament in Santa Monica, he met Matikozyan. "I was amazed at how he was thinking 10, 15 moves ahead," the coach said.
This summer, Sam has been invited to a two-day master class with Kasparov in New York.
In the fall, his father plans to take him to Brazil for the World Youth Championships, sponsored by the World Chess Federation.
If Sam does well, he will earn more points toward his next goal, becoming an international master.
His mother, Armine, worries that her son sometimes spends too much time playing chess.
"The thing is, though, he likes to play," she said. "Even in his free time, he goes to the computer and plays. I don't know … he's not like other children."
::
Sam and his father made the drive on a Friday in March from their Bay Area home to the Agoura Hills Renaissance Hotel for the three-day Western Class Championships, a U.S. Chess Federation-sanctioned tournament on the professional circuit.
The field included about a dozen masters such as Sam, seven international masters and one grandmaster, the top chess rating, held by about 1,300 players worldwide. Also on hand were an army of less-accomplished players who aspire to become masters.
The first night, Sam played an international master to a draw, the match ending just before midnight.
He slept nine hours in his hotel room, ate breakfast with his father and returned to the tables for the Saturday morning match with David Adelberg.
Their match seesawed back and forth for several hours and seemed headed for a draw. But then Sam began introducing complications, the first of which was the move to sacrifice a bishop. David recognized it was a trap and declined to take it.
Soon David made a small slip in defending his position, and Sam responded with an additional flurry of sacrificial moves, forcing David to part with his queen to avoid being checkmated.
After five more anguished moves, only a few minutes remained on each boy's clock. David grimly studied the board as the seconds ticked away.
Finally, he turned his king on its side and reached across the board to shake Sam's hand.
"Neither Andranik nor I really understood what he was up to at the time," Sam's father would say later. "When he showed us, we realized it was really a series of beautiful tactical combinations."
David's father, Dan Adelberg, an eye surgeon from Scottsdale, Ariz., later ascribed the loss to "one miscalculation, which certainly happens in many chess games."
In the hotel lobby, a few of Sam's young chess friends came by to offer congratulations.
"What do you want to do now?" his father said, suggesting they go to a nearby restaurant for buffalo wings and talk over the match.
Sam gave a thumbs-up sign.

Looking at the original problem;
if you move B to g2 then the King takes knight at C4 and, though it is easy to check, it still can't be mated with the next move.

Q to d3 is the follow-up mate after K takes c4.
