Here is a game from the recent GM rapid match, GM Akobian - GM Shulman with full annotations and commentary:
As we see with this game the Benko Gambit opening can be explosive and have a big payoff. Here Black quickly gambited on b5 and a6 to open lines on the queenside and the rewards were great. The active Black pieces soon overwhelmed the opponent to win the game in only 33 moves.
