What is the best continuation for white?

My brother and I played this game yesterday. I ended up having to leave shortly after this position but I saved it because honestly, I did not know how to finish it. We both had approximately five minutes left. The opening of choice for white (curradojr, me) was the Danish Gambit. He played into it strangely but eventually it led to a more typical position. As is typical of the Danish white needed to lay down a formidable attack and soon, before black gains a foothold on the board. More detailed veiws on the Danish Gambit here...
Black held his ground well but became tied up with a series of pins and skewers that led to this situation. The game up to this point:

Rook and Queen Problem

The maximum number of nonattacking rooks that may be placed on an nxn chessboard is n. This arrangement is achieved by placing the rooks along the diagonal (Madachy 1979). The total number of ways of placing n nonattacking rooks on an nxn board is n!(Madachy 1979, p. 47).

What is the maximum number of queens that can be placed on a chessboard. Eight queens for the usual board (Madachy 1979; Steinhaus 1999, p. 29).

The Big Cipher

Through the sunlight I entered the cool dank store. "Renaissance Books." They had told me. "You'll find what your looking for their." I scanned the place. No one was about. Stepping over piles of old books and magazines I made my way through a labyrinth of twelve foot high shelves that only stretched three quarters of the way to the ceiling. A towering wall of books with handwritten tags came up against me. Bodybuilding it said. Arnold Schwarzenegger's eyes peered back from the shelf, from half empty boxes on the floor. The old govenator in his youthful first life. A dark mans face appeared behind me "What are you looking for?" He stammered in only the way a half hermit used bookstore owner could. I don't know I thought, but Ill find it here. "Nothing." I said hoping he wouldn't start small talking me. "Thanks though." "Their are four more floors!" he croaked "look around." He Quickly disappeared into a fog of paper and words. I turned back to the sagging old shelves and my eyes finally adjusted to the darkness of the place. "Sports." I thought out loud, games must be nearby. My gaze went off to the left and my feet followed almost tripping over an old grey step stool straight out of the sixties. I caught my balance on Field Hockey and Golf. "You'll find what your looking for." they had promised. Only if I make it out alive. Four shelves caught my eyes as I stood up. Above, out of arms length, they hovered overhead as if the rest of the books had melted away. Chess it read on a small piece of taped handwritten paper. My mind raced. I should have known. It had been haunting me for weeks. Blitz chess. The kind you can only find in crowded chat rooms and dim lit smoke filled coffee houses. I frantically searched through the titles with my fingers and eyes. Blitz Theory, it stuck out, practically glowing among the other paperbacks. Found it, I thought. This has to be it. With one foot on the rickety old step stool I reached high and got hold of it. I hopped down gripping it tight against my chest and turned to the door. Their he stood, the man from before, with an unmistakable look in his eye. He knew all along. That's when I recognized him.

Memorial Day

General Orders No.11, WASHINGTON, D.C., May 5, 1868
I. The 30th day of May, 1868, is designated for the purpose of strewing with flowers or otherwise decorating the graves of comrades who died in defense of their country during the late rebellion, and whose bodies now lie in almost every city, village, and hamlet church-yard in the land. In this observance no form of ceremony is prescribed, but posts and comrades will in their own way arrange such fitting services and testimonials of respect as circumstances may permit.
We are organized, comrades, as our regulations tell us, for the purpose among other things, "of preserving and strengthening those kind and fraternal feelings which have bound together the soldiers, sailors, and marines who united to suppress the late rebellion." What can aid more to assure this result than cherishing tenderly the memory of our heroic dead, who made their breasts a barricade between our country and its foes? Their soldier lives were the reveille of freedom to a race in chains, and their deaths the tattoo of rebellious tyranny in arms. We should guard their graves with sacred vigilance. All that the consecrated wealth and taste of the nation can add to their adornment and security is but a fitting tribute to the memory of her slain defenders. Let no wanton foot tread rudely on such hallowed grounds. Let pleasant paths invite the coming and going of reverent visitors and fond mourners. Let no vandalism of avarice or neglect, no ravages of time testify to the present or to the coming generations that we have forgotten as a people the cost of a free and undivided republic.
If our eyes grow dull, other hands slack, and other hearts cold in the solemn trust, ours shall keep it well as long as the light and warmth of life remain to us.
Let us, then, at the time appointed gather around their sacred remains and garland the passionless mounds above them with the choicest flowers of spring-time; let us raise above them the dear old flag they saved from dishonor; let us in this solemn presence renew our pledges to aid and assist those whom they have left among us a sacred charge upon a nation's gratitude, the soldier's and sailor's widow and orphan.
II. It is the purpose of the Commander-in-Chief to inaugurate this observance with the hope that it will be kept up from year to year, while a survivor of the war remains to honor the memory of his departed comrades. He earnestly desires the public press to lend its friendly aid in bringing to the notice of comrades in all parts of the country in time for simultaneous compliance therewith.
III. Department commanders will use efforts to make this order effective.
By order of
JOHN A. LOGAN, Commander-in-Chief
N.P. CHIPMAN, Adjutant General
Official: WM. T. COLLINS, A.A.G.

Bishops Problem

Puzzles and mathematical problems on the chessboard keep me going when playing gets dull or Im in a slump. Their are a bunch of them on that I will be posting on over the next week or so. I am by no means a mathematician so I will leave out some of the more complicated equations that I dont understand and you probably dont either. Their is a similiar post about an original knight problem at . Try them out, often their is more than one solution.

Find the maximum number of bishops that can be placed on an nxn chessboard such that no two attack each other.

Find the minimum number of bishops needed to occupy or attack all squares on an nxn chessboard.

Above is an infinite chessboard reflected in a sphere. Look at it. It entices the imagination. Infinity reflected into infinity. That could make for a long game.

The Good Life

Sadly, The only newspaper at Quiznos today was the Sheperd Express. In it I found this amusing article about a young adventurous chess player. The Sheperd Express is an openly liberal newspaper here in Milwuakee. It leans so far left Al Gore probably gets a chuckle out of its absurdity on occasion. Its also owned by the most widely distributed paper in Wisconsin, The Milwaukee Journal Sentinal. The Journal Sentinal claims to be unbias of course. How that can be true is beyond me. Anyway, its also evidence that chessplayers are like everyone else. On with the story....

The Continuing Crisis
Peru's Emilio Cordova, 15, won the South American chess championship in January. Instead of continuing a life of chess, he flew from the tournament site in Argentina to Sao Paulo, Brazil, and moved in with a 29-year-old stripper. After Emilio's two months in the fast lane, his father went to Sao Paulo and retreived him, with help from the government.

Ginger: A good way to cleanse the pallet

A while back I sat down to play a leisurely game against chessmaster that I knew I would lose. I enjoy playing computer opponents that are out of my league from time to time to keep me honest. It was played using equal time (admittedly to my advantage) and turned out to be one of the best games Ive ever played against chessmaster. Play it out and let me know what you think?
Getting accustomed to the style of an opponent is natural. Its happened plenty with people Ive played in coffee shops over the years. I'm not sure if its the same with an entire program like chessmaster, but it would explain why I can now consistently beat chessmaster players up to 2200 but remain around 1700 on pogo.

Dont call it a comeback!

I had made a stupid error, costing me my queen. So I went into defense mode and had one of the greatest comebacks in my it out if you have time, it is a very fun game.

Analyzing two games

"The superior man, when resting in safety, does not forget that danger may come. When in a state of security he does not forget the possibility of ruin. When all is orderly, he does not forget that disorder may come. Thus his person is not endangered, and his States and all their clans are preserved." - Confucius

I just finished two games against my brother. Both were solid and his game is getting unshakable. I won the first game playing quite defensively as black. It was close and he nearly had me at one point until I withdrew my forces into a make shift but impregnable castle. As his forces prepared to lay siege it became the fortified castle under menacing pressure against the exposed king with room to run. He saw through my conniving schemes and subtle maneuverings, which is concerning as usually my strength is in deception. His tick was the use of time and that may be a small advantage to capitalize on in the future. When in a conundrum he no longer fears using as much time as he needs to solve the puzzle at hand.

The second game was no gem. I opened powerfully and gained an aggressive position. It was a clear advantage and his pieces were getting tied up in a defencive knot. Letting myself get bloodthirsty I lost sight of the advantages until it was too late. One combination in the middle game left me down material and on the defence until the bitter end. Had I taken the time and settled into the game appropriately I probably would have claimed victory. Unfortunately, that was not the case.

Sarkozy Victorious

France will soon be back on board with the rest of the civilized world. Even the majority of France is leaning right these days. How could this be when the French lead such better lives than Americans and Sarkozy's evil conservative policies will surely destroy their heavenly lifestyle? The extreme left will riot soon and make a mockery of themselves on the world stage. The price of progress is high these days. I for one am looking forward to watching the country transform itself and analyzing its consequences.

Is my brother a better chess player than I?

He did however leap to over 1800 on Pogo. He sent me a recent game with a rather eccentric opening. It appears as if they are both playing a strange version of the Sicilian. The game builds to a crescendo combination where black maximizes his position. I ran it through Chessmaster and except for pointing out one major combination error for both black and white it didn't have much to say. Its clear white is out classed as he plays too conservatively and moves his queen uselessly and too often. Black takes full advantage and white resigns after only twenty moves.
The game...
