Friendly Game - He keeps whooping my behind.

Alright, I'm playing games against my friend all the time and I'm struggling to deal with his aggressiveness.

At one point, I thought I had the game in the bag and before I knew it I was in trouble and starting making some real bad moves out of frustration.

Although it is a 7-day a move game, most of the moves happened tonight within an hour and towards the end I had just had enough. I'm not including the end because I'm annoyed and embarrassed.

Thoughts on this are much appreciated.

Sacing two minors for that f rook and pawn is usualy always a bad idea.  You lose develpment for one and in the end as fiveofswords stated "an inactive rook is not nearly as valuable as 2 active pieces"

11.Qf3, actually not so bad, but way better would have been 11.e5, because his knight has basically no good fields (Nd5 is answered with Qf3+ and you can pick up the knight the next move), so it has to retreat to e8 or g8.

12Qg3? you still have a better position, 12e5 would still be a very good move,

Thanks for the diagram. :) I always enjoy reading what people feel and think with each move.

So, I think the game was playable still, after move 21. After you traded most of his attackers, his king is exposed and your's behind pawns. With the queens on the board the game would have been dangerous for both opponents, but especially the exposed one. I only mention this since you mentioned how frustrated you felt, and this is more than enough for losing a game.

I'm no expert, but perhaps you don't need one yet so here goes. Move 12 was a blunder but it's psychology is typical. Been there many times myself. After defending an attack -kicking away knights in particular- it is a common mistake to focus on some sort of counterattack as if things have 'calmed down'. Better players are cautious of these backward defensive yet repositioning moves. The moral of the story? Knights are tricky! Especially if you have a queen nearby you should be on high alert, and not plan an attack before making sure it's a tempo ahead. Also, try not to get overly enthousiastic after a successful defence. The 'happy attack' is often deceiving.

Move 11. You explained why you didn't move your knight in front of your bishop and I agreed. What happened to that idea on move 16; Especially since your opponent had just weakened his king's defence with move 15...g6, making his dark squares vulnerable. I think 16.Bh6 was in order. It's certainly the first move that came to mind, since it's a common threat: trapping the king, threatening someday checkmate with Rf8.

Good luck with the rematch. ;)
