I've had a lot of experience with ogres, and I can give some advice:
- I'd strongly suggest Lore of Shadow, since low initiative is common in the Ogre book. I once killed 9 ironguts with a single Pit of Shades!
- cannons are great, but don't overestimate them. They have to kill an ogre before they bounce through to the ogre behind, so they aren't great at killing regular guys. And the stone horn has that rule where they halve the multiple wounds
- beware their shooting capabilities. Don't assume that his close combat will be his only asset
- normal I deploy at the edge of my deployment zone, but I usually stay near my table edge against ogres. Their massive movement means they can get turn 2 charges pretty easily
- don't try and kill a kitted Tyrant in close combat. I've lost too many expensive Generals/Grandmasters trying to take down the 5 wound, massive stat line killing machine. Instead try and win combat by killing normal ogres and hopefully run the general down
Hope this helps. Good luck
