OTB from a few years ago. I got a lot of cooperation from my opponent as you can see. I spent around 20 minutes checking and re-checking before making the rook sacrifice on move 17. The way my opponent had been playing I doubted that he would see 17...c6. If he takes the rook as in the game it is not really a sacrifice as it wins by force.
When I showed this game to Tim Mcgrew (chesscafe writer who tought me the BDG) he saw Rxf5 as soon as I had moved h5!
I have a classic BDG 'swindle' that I like too. I will have to dig it up.
