Live shorthanded game with overs - general strategy question

[DeathDonkey]

I had the fortune of ending up in a 5 handed 20/40 game tonight where everyone had overs buttons. So basically it was increments of 20 preflop and then jumped to 40/80 limit postflop. My opponents were all pretty reasonable, a couple were probably too tight and the others were a bit LAG - it wasn't a good game by any stretch of the imagination, but it was the only one going and I have a big ego.

Anyway, what starting hand adjustments would you make in a game like this? Way back in the day I played in the miniblinds games on UB so I had an idea in mind - I thought immediately that all pairs go way up in value as a flopped set has great implied odds. Suited connectors etc. seem less good to me than usual because of the high price I will pay to draw postflop.

Also do you think there is much more value in slowplaying / tricky playing? I lost a big pot to a borderline maniac LAG when he just called my open raise with AQ in the big blind (I opened AJ) and an ace flopped.

Thoughts?
