All rubbish pitches play slightly differently. Spend a bit of time watching from the sidelines the bounce and what the bowlers are doing. Then formulate a plan. Low wickets getting forward is key. Lifting decks playing off the bat foot or using very soft hands. If it's doing a bit of everything then pick a plan that works for you. I would say attacking the bowling is a great strategy, I've seen the odd slogger change the nature of a pitch simply because he's put the bowlers off a length. Takes a bit of balls, no little skill and alot of luck but don't underestimate what a few big shots can do. The complete opposite strategy is simply to hang in there. By hanging around you hope that somebody is having an off day and feeds a few full tosses. It's quite possible the pitch might ease or you'll start seeing the ball better. Time at the crease does that.
