Well, my wife was soundly trouncing me. She was keeping her hand size large and using colored flights to really pound me with gold piece deductions. In fact, I almost gave up until I had an absolutely massive round in which I won a pot of 24 gp and tagged her for a 10 gp penalty as well! In a game with only 100 gp that's a hefty sum!
From there, I managed to put together some colored and strength flights myself (it's surprisingly difficult to do but it really makes a huge difference!). I slowly wore her down until she had only one gp left... a gp that I took with a large red dragon and won the game. Victory is sweet but a come from behind victory is sweeter!
