I'll (cheekily!) answer your question Colbro!

I would raise more with JJ here. The problem with a raise of $5 is that if one person calls you then the next is getting over 3-1 call etc. I'd be making it $6 or $7 - so I really know they're serious if they call. Alternatively a 'sweetener' raise is reasonable IMO - maybe to $2 or $3, but then you're relying on playing very well and/or hitting your set. I'd be quite happy to take the money already in the pot so I'd incline for the bigger raise.

Disagree about the AJ above Jez - makes sense (some!) on the flop and on the turn, but it would be a very brave/foolish call on the river. Realistically what hand could someone have to bet the pot on that river when they've a good chance of taking it down via checking with a mediocre hand. You have to think it is a King looking for a check raise on the turn, KJ, 22 or 33. Will TT or the lower pairs bet this much - from their point of view what hand that raises pre-flop can realistically call them here?
Also I'm skeptical that any/many decent NL players will raise 3 limpers with AJ - it can't stand a re-raise and there is a decent chance they're already behind to AQ or AK (behind them)
