A very well-crafted show, occasionally a bit slow and drab in the 1st act, but solidly constructed and directed thereafter. I especially appreciated the "follow-through" aspect of the scene where Vic Perrin, who decides to try his luck at gambling, first seeks advice and a quick "how to" session with a wily gambler that Matt has just thrown out of Dodge.
Somehow this scene lent the plot a lot of credibility, instead of just jumping into the scene with Vic and his ill-fated attempts at gambling. Similarly, the rest of the show progressed naturally and very effectively, always with a sense of tension, as things became increasingly complicated and even dangerous as the time for the big fight approached.
Lots of great interaction between the main characters, featuring real-life boxer Wilhelm von Homburg and Allen Case as the Lieutenant, who had a successful career as a SINGER, including a couple of Broadway shows (what a surprise to watch this episode and realize that I have the recording of the 1959 musical "Once Upon a Mattress", with Mr. Case playing the romantic lead, sitting on my shelf). He's very good in this episode....quiet, courteous, yet firmly in command. BIG fight scene is the high point of the show, with good ol' Shug Fisher (an excellent Western singer himself) in a featured role and Louie Pheeters pressed into service as Otto's "trainer".
There's a lot to enjoy here, worth more than one viewing. And the ending, thankfully, was a nice one. LR.
