Hello all,

I am running two tournaments of 5 players each for the rating ranges 1001-1200 and 1201-1400. I had promised to analyse all the games in both the tournaments.

The links for the tournaments are given below.

Analysis of tournament-1 games will be posted here. For  analysis of tournament-2 games, please check the below link.

Stay tuned for the analysis of the games. Already 5 games are finished in tournament - 1 and I am lagging behind in my analysis. Today I will post the analysis of two games.

In comment #3, I have marked 16. Nxe5 as a mistake, but it still was okay for white and it is actually not a mistake. If at all if there is a mistake, then it was 17. f4 as it opens up the white king. Black immediately gets a strong attack but fails to execute it correctly.

When the king is in danger, involving in tactics to win material is generally not advised.
