I like to split in half and coat the ends , let dry at least 4-6 months in this form . Then after some of the moisture content has left split into smaller quarters ( that is if the log is big enough), I have found with yew that if you reduce the log size to quickly it tends to get squirly when drying.
It is not just an issue of drying either, more of a seasoning of the wood, yes it does change as it drys but best over time . I like about two years for my yew.
As John said yes you can make it work quick on some cases but I have found time is the best policy for a larger percentage of success.
