MY BEST WIN IN MY HISTORY OF ONLINE CHESS!
It's good.
Not to be a hater, but that queen and rook was a miss, not doing that had to be a miss. Other than this, it's a really good game. Mine is a like 5 move resignation
This was also a great game!
Most blunders at intermediate level - and probably most at high level - are the result of tunnel vision. In this game black probably played 20 ... h5 with the intention of 21 ... Ng4 threatening 22 ... Qh2#. The problem with this reasoning is that it takes no account of what white might do.
Black probably was looking at the many defensive moves that white could have made on moves 21 and 22, and completely failed to consider that he might (and did) have a strong attacking move. Congrats on your win. It wasn't just because he blundered, it was also because you had been able to hold your own up to this point, despite the strength of your opponent. Game review evaluates your playing strength for this game to be 1950. Well done.
