Little bit of analysis

I played this game against my 11 year old cousin, rated around 1600 OTB. He plays black, but I do not think he plays at 1600 level here. Can you have a quick look at this game? I started with intention to play Colle system but he surprised me with his second move. Did I make any obvious opening mistake?

P.S. I won this one, but since he is working with IM I think he will start to slaughter me soon 🙂

I prefer 8.f4 or 8.Ndf3 instead of 8.Nef3, which just loses time (the piece just moved to e5 two moves ago!)

You called Black's 2nd move a surprise, but the reality is, Black can play a number of things against the Colle, because it's slow for White compared to other, more aggressive, openings.

25...Rd8? lost a pawn, and 29...Qd6?? missed the threat to f7. The game is practically over after that move.

Here is another one!

I think we played better here.... What would be your rating estimation? Is that near 1600 performance or lower?

that was poorly played by white ... g4?? what the hell were they thinking!

Yep, he does it every time, not caring much about solid castled position
