The Trap (Game 5,White)

Often laying a trap is an effective way of defeating the enemy.

Deliberate vulnerability. 

The opening progresses normally but White's doubling the Pawns on the c column makes Black over confident.

Worth trying. 

Black seems to think that the c column is a good spot to attack.

Set the trap. 

White offers the g2 Pawn for free.

Too tempting. 

Black decides that preventing White from castling is to good an offer to refuse.

Spring the trap.... 

Now it's clear! White has complete control.

Open wide. 

There's nothing that Black can do. The only thing it can do is try to escape through e7. White won't let that happen.

Simplicity. 

The Checkmate is not spectacular but does the job.

Self-destruct (Game 4, Black)

Often you lose a game because you make some disastrous moves rather than your enemy making brilliant moves. This is usually due to a lack of strategic understanding.

Just move once.

White makes the mistake of moving the Knight twice. It is usually best to move pieces just once in the early opening. Of course there are exceptions.

Stay-loose

 The opening proceeds normally, but Black has cramped up the Queen  Bishop which does not go unnoticed by White.

Short termism

White backtracks the Queen Bishop to protect the Knight on c3 from the Pin as well as to leave g5 open for the Knight.

Watch out  for traps.

White seems determined to capture Black's Queen Bishop on e6. This is in fact a trap.

Inertia.

Despite Black threatening to Check with Bf2,White proceeds to exchange the Knight for the Bishop. This is as though there is a momentum that cannot be overcome. A good player must be able to change their plan at any moment.


Penetration.

Black gladly accepts the offer. The f-collumn is also open and White cannot Castle. A clear advantage for Black.

Defence bad?!

White seems to realize the trouble it is in and moves g4 to stop the Knight from joining the attack.

Black offers to exchange the Bishop for the Rook which White declines. This may seems good tactically but allowing a protected enemy Bishop deep in your territory is a strategic blunder.

Brilliant sacrifice.

Black makes a truly brilliant move in Knh5. This opens the way for the Rook as well as moving the Pawn out of the way.

Retreat!

White's Queen retreats in the face of such concentrated attack.

Fortune favours the brave.

White makes a reasonably good move with Be3 but Black counters by offering to exchange the Rook for the Bishop. White now realizes that this would lead to Checkmate in two moves.

The back door.

White has to move the King Bishop to e2 to prevent Checkmate but Black makes  a brilliant move with Rh2, threatening to Checkmate via the 1st row.

The only thing to do.

White decides that the only way to stave off defeat is by sacrificing the Rook.

Last resort.

White has to move the Queen to c1 to prevent Checkmate and risks exchanging the Queens.

Black makes another brilliant move with Qg1 threatening to end the game with a discovered  attack Checkmate..

The future is bright.

That move is so brilliant that White is forced to suicide the Queen.

Just too brilliant.

White has to move the Knight to b1 to prevent Checkmate and to create an escape route via c2.

Black counters with a ridiculously brilliant move with Bc3. This blocks the escape route completely

Smooth operator.

With no escape possible, it's just a matter of time. A series of brilliant moves is capped by an equally elegant Checkmate.


Alternate ending:
This ending is far less glamorous. 

The long reach. 

The open f-collumn is absolutely disastrous for White.

A win is a win! 

The Checkmate is anti climactic. But it's still a great victory.

In the end, the mistakes by White, it's ignorance of strategy and a couple of brilliant moves by Black are the takeaway from this game.

Dangerous exchanges (Game 3, White)

Some players have the bad tendency of exchanging pieces too early. It's better to wait until your attack is in full swing before instigating exchanges.

Wasteful exchanged.

Black makes the mistake of exchanging the Knight for the Bishop too early. The result of the exchange does not yield any advantage and reduces the number of available pieces.

Create an opening. 

White entices Black to take the Knight on f3 to open the g-collunn.

Black takes the bait.

Press the advantage. 

The vulnerable g-collumn gives White a great advantage. Black has to sacrifice the Queen hoping to Queen the pawn. 

Total clearance (Game2,Black)

Pawns may seem weak bit they can create a strong defence and form a road block impeding your attack. So getting them out of the way can be beneficial.

Efficiency.

The opening f3 is problematic. It puts the King in a vulnerable position immediately although it could be used as a bait for a trap. White's a3 is complete waste of turn. So Black has a clear advantage in the opening.

Stay on target. 

Black intelligently goes directly for the King while White makes an effectual attempt to use Pawnadvance on the Queen side. This is off target.

White begins to get the Pawns out if the way by sacrificing the Knight. White's brilliant move Nc3-d5 is easily handled and in fact benefits Black by  putting the Queen in a superior position.

Inevitable.

White is in trouble. So when Black moves the Knight to f6, which  threatens to join the Knight in the attack, White has no choice but to exchange the Queen Bishop. But this only succeeds in opening the g-collumn further.

Desperate.

White is desperate now. So when Black takes the Knight, White has no choice but to capture the Bishop with the Pawn to prevent Checkmate. The result however, is to completely open the g-collumn.

The end.

It's over. White just sacrifices the Bishop and Queen to delay the inevitable.

Loose end.

Just a short end Game to close it.

Sacrifice (Game 1,White)

Many experts would advice against sacrificing any pieces saying that that's the opposite of good Chess. However, often sacrifices are an effective way of breaking down the enemy's defences.

The calm before the storm. 

Both sides make very solid openings, controlling the center. White has a slight advantage by developing both Knights but Black has both Bishops in perfect attacking positions.

A good sacrifice. 

White sees an opportunity to break down Black's defences by sacrificing the Queen Bishop. This must have been a complete surprise to Black.

Enter the Queen.

With the way wide open White moves the Queen. But in order to do this, the King Bishop has to be moved up to prevent  18...  e4 that would block both the Bishop's and Queen's movement.

Black is distracted by an opportunity to capture the Rook.

Another sacrifice. 

White let's Black take the Rook so as not to waste a turn.

White moving the Knight to e2 then g3 is quite crucial. Why exchange pieces unnecessarily?

Nowhere to go.  
      

It's over. The Black King is completely exposed with so many enemies having him on their sights. Black can only delay the inevitable by sacrificing the Queen.
