White makes this move and black resigns (chess danish gambit)

Danish Gambit is a chess opening I am using in almost 99% of my chess game nowadays. I like Danish Gambit because it is simple, it is effective against the aggressive player and it is almost perfect as compared to the English opening.

The beauty of Danish Gambit is it tricks it’s opponent deep into it’s territory by giving out piece after piece and then before the opponent can fully develop his pieces the Danish Gambit’s player will start to press forward and eventually destroys all the opponent pieces and finally wins the Game!

You need lots of practice and prepare to sacrifice lots of your own pawn when you are playing the Danish Gambit opening. It is a fun chess gambit to play but it is not for the chess beginner who has no idea what to do next when the Gambit goes wrong!

Black piece vs white piece who wins this chess game?

It is the summer time and the best method to cool down your body is to play a game of chess. My opponent who plays the white pieces is a IM but he is not playing well today as you can see there are many holes in his game. We both start our first few moves in the standard fashion. Then the situation on the chess board starts to change after he has made a very strange move by exposing my “left flange”. I know what he wants and I also can see there is a big hole in his game! The game continues and I further solidify my position on the chess board by bringing out my left knight into the game…

The last few moves are the one that really secure my victory against this player who ranks higher than me. He resigns after I move my knight…

How to stop windows from auto downloading updates to your computer?

Some windows users just do not want windows to keep on auto downloading the softwares or updates that they don’t need to their computer. If you are just like me who uses a limited bandwidth’s broadband then those auto downloading jobs will really cost you lots of unnecessary bandwidths. If you have decided to disable the windows auto downloading job then the below method will help you out.

The method I am going to show you does not guarantee will 100% stop the auto downloading job because windows os actually can start the auto downloading job again if it wishes to, we simply cannot beat the operation system. However this method will certainly help you to temporary stop windows from auto downloading files into your computer. Here are the steps you need in order to temporary stop the updates from windows os.

  1. Open up the Windows OS Services manager. Find the Background Intelligent Transfer Service windows os
  2. Right click on it then select Properties to open up it’s Properties panel, under Startup type selection box select Disabled, also click on the Stop button below the Service Status to stop the auto downloading job if you need to, then click on the OK button to confirm your action.                                              BITS
  3. That is it! Now windows will not download anymore updates until you restart the auto downloading service again.

Good or bad, you decide:-

Do you really want the auto updating service to stop? There might have some important updates from windows that your will miss out if you disable the auto downloading function.

How to create a star on html5 canvas with canvas api?

This article will show you how to create a star on html5 canvas with the canvas api. Basically what we need here is a whole bunch of points for us to plot the star and then we will loop through those points and connect them together with line.

var context = document.getElementById('canvas').getContext('2d');
context.strokeStyle = 'yellow'; //assign line color to yellow color
context.shadowColor = 'rgba(144, 145, 148, 1.0)'; //assign the color of shadow
context.shadowOffsetX = 1; 
context.shadowOffsetY = 1;
context.shadowBlur = 1;
context.lineWidth = 3; //set line width
context.lineCap = 'round';

//the points we need to plot the star
var array1 = [[326,248],[328,248],[331,248],[333,247],[336,246],[339,245],[344,243],[351,240],[359,237],[369,232],[379,227],[401,217],[413,211],[428,204],[441,197],[456,189],[471,183],[488,178],[523,169],[561,160],[577,156],[590,153],[613,147],[623,145],[630,143],[642,140],[650,138],[654,138],[656,137],[655,138],[654,138],[653,139],[652,139],[652,140],[650,141],[649,142],[646,144],[644,146],[642,148],[640,150],[637,153],[633,158],[626,164],[621,168],[616,172],[607,181],[598,191],[587,204],[567,228],[553,244],[539,262],[523,279],[510,296],[497,313],[484,330],[474,345],[464,357],[455,369],[446,379],[441,386],[430,399],[424,406],[419,412],[416,415],[416,417],[416,415],[416,408],[416,388],[416,380],[416,363],[416,344],[415,311],[415,286],[414,261],[410,236],[406,214],[402,194],[397,175],[394,156],[392,137],[392,121],[392,109],[392,98],[392,85],[392,78],[392,72],[392,70],[392,71],[395,77],[405,92],[414,106],[424,120],[434,132],[444,143],[454,156],[465,166],[475,173],[484,182],[497,192],[509,203],[522,213],[537,223],[549,234],[562,244],[580,260],[590,272],[602,287],[611,299],[619,310],[626,319],[632,326],[635,330],[638,334],[640,336],[639,336],[635,335],[629,333],[614,327],[600,323],[584,317],[570,312],[557,308],[547,304],[540,301],[531,297],[524,295],[516,291],[509,289],[503,288],[495,284],[486,283],[479,281],[471,279],[462,277],[458,276],[452,275],[447,273],[442,273],[435,271],[431,271],[426,270],[420,268],[412,266],[408,265],[401,262],[397,261],[393,259],[389,257],[386,257],[382,256],[378,254],[374,254],[369,253],[365,252],[361,252],[358,251],[355,250],[352,250],[348,249],[347,249],[346,248],[345,248],[344,248],[343,248],[342,248],[341,248],[339,247],[335,246],[332,246],[330,246]];

Great chess opening Danish Gambit reviews

When the first time I look at the Danish Gambit chess opening I was simply shocked that how on earth can someone even thinks of this masterpiece? When you see this opening in the first time you will really think that your opponent must be out of his mind by giving out piece after piece but before you realize that a trap is waiting for you at the end you are almost done! Nobody can deny that danish gambit is the work of a genius, we lost pieces at the beginning but at last we are the winner, that is the beauty which hides behind Danish Gambit.

The mindset of the Danish Gambit player:

Get ready to lost as many pieces as you need in order to achieve the final glory.

The mindset of your opponent:

He thinks you are silly but before he realizes his mistakes he is over!

The mindset of the creator:

He comes from a culture and civilization which is willing to give up everything just to achieve the ultimate victory.

We really need to practice this formation for at least 100 times before we can master it, we also need to take a risk and prepare for a quick lost if we have decided to use this Gambit as our commonly use chess opening. Once we have mastered the Danish Gambit we will see lots of weaknesses and holes in our opponent game during the match which we can then capitalize and easily defeat even the strongest opponent on earth such as the Russian or the US player!

How to draw circle on html5 canvas

Drawing circle on HTML5 canvas is relatively simple. We just need to define the radius and the center point of the circle then we can start to draw circle with the canvas’s context object.

var canvas = document.getElementById('canvas');
var context = canvas.getContext('2d');
// center point of the circle is at the center of canvas
var centerX = canvas.width / 2;
var centerY = canvas.height / 2;
var radius = 150;

context.beginPath();
context.arc(centerX, centerY, radius, 0, 2 * Math.PI, false);
context.fillStyle = 'blue';
context.fill();
context.lineWidth = 1;
context.strokeStyle = 'black';
context.stroke();

The outcome of the above program is as follows.
