What can happen when one attacks just because they feel aggressive

 For some reason the name Nicholas Ernest de Firmian flashed through my conscious after reviewing the following chess position illustrated in the diagram. I think Nick and GM Chistiansen were close back in the late 90s. Larry works for USCF and I think Nick distanced himself from the Royal Game. I was at a tournament in Florida when Larry, in a Jacksonville Hotel Bar, lamented the truth that the US is owned/run by insurance companies. He is a good guy one time giving a 60 board simul in Lubbock Texas pre Susan Polgar.  

After a few moments of ennui, I realized it was because Nick espoused/endorsed Jeremy Silman's famous work titled "How to Reassess Your Chess" where he made the term imbalance a wildly popular chess teacher word. Don't know if de Firmian made any money  off calling Jeremy's book the most seminal positional piece of chess literature since My System. 

ICC player extrauniversal2, from Denmark, commenced an unjustified attack which resulted in his King side pawns being maimed. White rejected winning material in favor of long term positional squeeze. The Danish player committed the chessic sin of attacking because he "just felt like it" and had to resign 12 moves later. 

Meran Defense in Reverse

I believe it was IM John Donaldson, contributing editor to the wildly popular pre internet magazine Inside Chess, who wrote an excellent opening manual on the Meran variation of the Slav Defense.

The opening was exceptionally popular and effective to the extent that anti-Meran White systems were devised. The idea behind the opening was to wait until White developed his f1 Bishop and then give up the center with d pawn captures c pawn. When White recaptured with his twice moved prelate, Black would play a6 threatening  b5 with a tempo on c4 Bishop.

The pawn pawn move b5 also cleared b7 for the Black c8 bishop to occupy. Cliff Bunch, a high intensity Houston player, believed Black was already better not 10 moves out of the opening.
