3 queens in 5 moves

Even though Street Chess is a serious tournament (with prizes and rating points at stake), I still like play in the 'coffee house' style, especially just after I've lost a game. For those unfamiliar with the term 'coffee house', it is a style of chess based on speculative attacks, sacrificing material, and trying to win by bluffing your opponent that your attack is much stronger than it really is.
Yesterday I played a good example of all of the above, with the added bonus that the banter between myself and my opponent attracted the interest of a large number of spectators. I was black and my opponent opened with an interesting variant of the Colle, in which he develops his knight to g3, in part to support the thematic e4 break. I decided to go after this knight with my h pawn. By move 10 he had committed the cardinal error of moving some pieces twice in the opening, while others he hadn't moved at all. With my lead in development it was a question of where I was going to crash through, which he then answered for me by castling. I picked up a couple of central pawns while he decided to commit further sins by sending off his queen on a pawn hunting mission. I offered a piece soon after, which he declined, so I sacrificed it 2 moves later. In true coffee house style my 19th move (Qg5) looked quite strong, but actually wasn't. He firstly played a diversionary capture with 20.Nxc5 and after I replied 20. ... Bxg3 he thought for a while and then loudly exclaimed "But it's check!" 21.Qxd7+ Kf8 was quickly played, and then with a flourish he blocked any discovered attacks with 22.Qg4 This turned out to be a losing move as I now recycled my queen, not once but twice, all in the space of 5 moves. When the smoke had cleared I had a forced mate, and he was congratulating me on my 'lucky' win!
