That is a long title... I just want to share the first BG game I lost OTB. I lost because I was too focussed on getting my rook out with a5 in the Bc5 variation. Then I defended horribly, and got wiped off the board against a guy rated more than 200 points less than me. So... enjoy and learn, don't make the mistakes I made! That f4 threat in this variation is kind of real...!

No offense, but 10. ...a5 is just not a good move in that position.

The rook lift is an inappropriate manouevre in the Smyslov-Spasski Attack. You never even got the rook to a6. Instead, Black should focus on securing the kingside on counter attacking in the centre.10. ...d6, regrouping the e5 knight to f6 is the way to go, e.g. 10. ...d6 11. f4 Nd7 12. Bd3 Nf6

Your opponent didn't continue optimally, either. 12. a3 doesn't match the plan of a kingside attack. 12. Bd3 is more common, with the setup Bd3/Qh5/Rf3

In the end, don't dismiss 4. ...Bc5 in the Adler variation because of one loss. That move wasn't the problem. Just go through your game again carefully and learn to deal with the Smyslov-Spasski attack. Black can achieve decent play there. Your opponent didn't play flawlessly, he just had the advantage of catching you on his turf.

Make it your turf and show him who's boss. No one messes with the BG! Good luck!

Thanks for the encouragement Aeric, and your comment on continuation is right.

 My problem in OTB chess is that I have had very little time to study for more than a year now and it is becoming a problem. I'll need to take a few days off to wipe the dust of my opening repertoire . 

If I remember rightly one of the author of Budapest gambit book (Taylor ?) dismissed

4... Bc5 idea as wrong. It doesnt mean he was right but I prefer to concentrate on more reliable (simple) variations first. This one I leave as a weapon against weaker opponents who know nothing about Smyslow/Spasski let alone Smyslow-Spasski trick

Yeah that was Taylor...  but the Nd2 variations in the main lines with Bf4 are not that easy to play either ... I always considered the Bc5 lines the easiest to play because you get the pawn back with good play. And then if you get the chance, the Ra8 can work wonders. But I missed some common sense in my game, so I decided to post it as some kind of warning to others. Going forward I will start mixing the variations more often to give my opponents a little bit more work when they decide to become Budapest Gambit experts overnight when they have to play me!
