Beautifully Set Trap!!
Lesson to other beginners, and I have made many similar mistakes... always consider all options when building a tactical plan. He eyed the prize but didn't consider my options in advance. Once he moved for the prize, it was over. My chances for mate we're 100%, considering 3 of his options, after he moved for my Q/R.
GG, considering his blunder. Before that, he was playing rather well.
