I would call that horsing around in a tight little corner. Paired ponies mated under the auspices of the Bishop under the nostrils of the opposing King.
Nice knight mate

My post is just silly word play. Your ending was artistic like a matador finishing off his opponent in a bull ring. It was very fun to watch. It put me in good spirits and set me off on a word ramble. The important thing is that you got a wonderful victory and I enjoyed watching it. Al's well that ends well.
This is online game i finished today.Its nothing really special,but the mate was quite fun,and i just wanted to share.
Cheers
