I played a 3.8k game of BFG today, 3.8k of Imperium vs 3.8k of Chaos. (We had a guest player, Harry, from Albany who found us on the web). I played Imperium. The scenario was Fleet engagement; we chose Wedge and Chaos chose Cross. The two fleets deployed on long edges parallel to each other facing opposite direction. This prevented the Imperial fleet from charging Chaos with its armored prow. We did what we could to maneuver toward the enemy but seemingly always one arc behind. This led me to realize that Imperium should not try to come directly toward their opponent but should instead come on at a converging angle so that the current enemy ships are toward the one corner of our front arcs, expecting that once the enemy ships move, they will remain in the other corner of our front arc.
Previously I have also been reluctant to leave bomber markers on the table because of fear of being taken out. However, I think that the chances they will be taken out by ship fire is remote (requiring 6s to hit). When enemy carriers launches fighters to take out your bombers they aren't launching bombers or assault boats against my ships. In addition, interesting enough, damages taken by attack crafts are renewable (with re-rolls) similar to shields. By having bombers out, I have alsos extended the range of my bombers to 40cm per turn.
Final thought, the obvious thought. Concentrating fires to cripple ships is more effective than spreading fires across many ships' shields.
