I think that I have to try to make resonable moves much quicker. For instance weather I should play Bd3 or c3 should not take longer then a couple of sec, while I spent like 2 min on this in the game. Bd3 would have been better and I did consider playing it.
I found that I liked a4 in the game since a5 sometime would make his queenside pawns less flexible, but I should try to take advantage of his uncoordination and less space and try to hit in the centre or kingside like you said. The reason I didn't play Re1, Nf1 idea was that I was not sure about it. It looked like he had too many pieces on the kingside for an attack and his g6 knight looked like a good defending piece. I think I rely quite a lot on my opponent to make errors instead of playing aggressivly. So this a long with using the clock better should be good to improve.
e5,Re1 togther is good also because I don't really have to watch out for f6 since I just take if he plays it opening the e-file. So there are lots of good points with these three moves as they constitute eachother well. Keeping the pawn of e4 was still OK I think since I always have the options of playing exd or e5 later. I was very happy when he took dxe saving me the effort of re-routing my knight.
I think Nxf6 strategically was a good move though since on Qe2,Nxe4,Qxe4 he has Qd5 trading queens. Besides, when his bishop got to f6 I thought it looked like a not so good piece there. Also I didn't want to have to recapture with my bishop if he traded knights on e4 since it's more exposed on e4. About here though I was starting to find myself in timetrouble why I played moves like Be3. I thought it was a little funny that I missed mate and lost the game 1 sec later, that's why I posted the video.
About Qe2. You are right Rae1 is more aggressive with the idea of f5. But after h6 by black f5 looks to me to just drop a pawn, or? Ofcourse later I should have took on e4 with the rook but I simply forgot about it.
Thanks also for the very good idea of e5,Rf1,Nf1 and of playing f5!I learned a lot from watching the video afterwards like that I need play more aggressive ideas like the ones you suggested. Scare my opponents a little more without scaring myself
. The site by the way is instantchess.com and the first 60 games are free. Have a look at it and post what you think. It's very easy to use and I might buy a membership there. The problem is I don't know if any good players play there, if not that's not very fun.
