Master Chess Analysis 4th Session

Hello All and welcome to the 4th session of my series where I analyze the games of Chess.com members,

Today I will go over the 8 games that were sent to me to be analyzed. The games all had different ideas and concepts that are crucial for a good player to know, understand, and be able to apply.

An in depth analysis of each game is provided below. The games come from players of all ages, strengths, and ratings. If you want to have your game analyzed in my weekly blog please post it in the comments

Now, let's begin

-------------------------------------------------------------------------------------

1) N.A. - Hlgchess 0-1

Now we have arrived at the following position:

Here, white has the choice of two moves --- 8.Nf3 and 8.Nd3 ---- and our first key concept --- but then struggled to develop the c1 bishop, and the moves wasted to develop the bishop led to the loss of the e4 pawn and the game: sometimes the position itself and piece activity are worth more than material --- In the game, white chose to try to hold on to the e4 pawn with 8.Nd3 but then struggled to develop the c1 bishop, and the moves wasted to develop the bishop led to the loss of the e4 pawn and the game

The game continued: 

9.Nf4 Nxe4 10.Nxe4 Rxe4 11.d3 Re8

12...Qf6 13.Re1??

White has just blundered with 13.Re1?? - How do you finish him off?

2) Pokemonmasterboy - ??? 1-0

Here, Black played the move 18...f5?? 

Remember: When pushing pawns in front of your king, always ensure that there is no forced tactical continuation where your opponent can win. Also, if your opponent is attacking your king with pieces or pawns refrain from moving the pawns in front of your king unless the move is forced because when you move one pawn, it gives your opponent a target and sometimes it severely weakens the surrounding pawns

Now, how to punish black for his mistake?

3) Ocsed1 - Kamil1982 1-0

This key point is due to the move that black played in the previous position, 16...Qd5, trying to hold on to the feeble e4 pawn... This key point is directly tied to the key point from game one in that

You should not attempt to retain material if it allows your opponent to gain key tempi as this will most likely lead to the win of not only the material that was being retained, but also usually a significant amount of material in addition

after 16...Qd5? white gained many tempi with the moves 17.Bb3 Qf5 18.Ng3 Qd7 (back where it started) 19.N5xe4 Nf5 20.Nc5 Qc8 21.Nxf5 gxf5 22.Bh6 Bxh6 23.Qxh6

and now black threw away the game with 23...Nxd4??

Can you finish black off?
