Welcome

Honestly I have not had too many Oliva duds. Occasionally one will run a bit or not taste perfect. My guess is that you left it out of a humidor too long before you smoked it. Hence the runs because the outside dryer tobacco (wrapper/binder) burn faster and leave the filler behind.
Puff, Puff, Puff. The only cigars that won't go out without constant puffing are machine rolled and dry. Take short puffs more often rather than long drags that tend to get it too hot and also contribute to runs. Learn the art of puffing just enough to keep it lit. It will stay cooler, produce more creamy smoke and taste much better.
Choose a beverage that enhances the cigar. There are 1000 different opinions. Personally, I like to swish a shot of aged Tequila, no lemon or salt. This wakes up my taste buds and cleanses the palate.
