Even though I am lower rated I think 2000+ players have probably a better grasp at positional chess, for instance, white giving up his good bishop on move 16 is bad I think, but that was the move Be3 to start with. Qe2 would have stopped the threats better.
But black also plays a few non moves, like Rf7, the other rook is more important because it doesnt do anything. I think if you want to take advantage of you taking with your pawn isn't it better to get a rook on g6 instead of a battery on the f file which can be defended by white with his own battery or with f3 (although weakening the kingside)
Then white tries something on the a file that fails, I think not enough time to think further then doubling up the rooks on the a file which is easily defended ( you always have the rook on f7).
Nice analysis on the end :)
I have been playing a lot of blitz here over several years. I have also played quite some 30 minute games.
Yesterday, I decided to play a 45|45 game, being quite careful to actually use the time and pretty much force myself to think everything out before moving. So, my opponent and I, both around 1550, play 46 moves before I have to resign. Chess.com computer analysis says 5 inaccuracies and 1 blunder. No mistakes involve loss of material, forks, pins, skewers, etc. ... they generally involve, at least it seems to me, imperfect assessment of pawn formations. Late in the game, my opponent allows himself to be forced away from a key file, and this should be good enough for me to win, but instead I underestimate a passed pawn (or overestimating my ability to get a rook back to stop it) so it's me that makes the fatal mistake. And even that, I think, has some psychological aspects I could improve on if I got used to playing at this pace.
I guess what I'm saying is I'm surprised at us. I don't say this looks like a master game, but we are class C. There are four rating classes between us and master class. What distinguishes them?
I'll post the game with some offline analysis I did with Komodo in case anyone cares to comment, either on the game or the general level of play at slower controls.
