This game from the last round of the European Team Championships (won by Germany) reminds me of why I hate Benoni formations. Radjabov, being a brilliant tactician, is no doubt attracted by the latent dynamism of such positions. But underlying it all is the inherent lack of space.
In the end White lashes out with 29.g5 which the engines will immediately castigate as being ‘unsound’. But White has to create counterplay in such positions.
