There is no harm in folding this preflop as you can be dominated by players limping with hands like JQ, QT etc but I think I would probably flick it in and see a flop given the pot odds and the fact that most limpers will have very weak hands. You just have to be fairly cautious postflop.

The flop Q53 is probably one of the best you can hope for. In this spot I would keep it simple in an unraised pot and lead out for about 1/2 pot. When you lead in a spot like this I think the other players are going to play pretty honestly. You are leading into 3 players so they must think you have a Q in your hand at least for made hands. For non made hands they probably put you on flush draws. Obviously, if called I would then try to check it down unless I improved further. If raised, I would mostly fold as we beat nothing other than a flush draw but are going to have to pay a lot to find out.

As played the A is a bad card for you. Loads of limpers do so with A rag type hands especially suited. There is really no reason for villain to jam with a Q as he has showdown value in position so I suspect this is a weak ace or maybe ace rag that has made 2 pair that is jamming to “protect” their hand. It may be a flush draw as well or some kind of straight draw I guess but I'm never interested in paying to find out in these spots. Just fold, make a note that villain likes to overjam and hope to get a similar situation when you are strong and snap him off.

I may be a “spewer” but there is precisely 0% chance that I fold this hand pre-flop, given the lucrative odds.  Other people may advocate folding given the potential for domination, and they are prudent, but I'm not one of them.  However, if you are going to play this style it is absolutely paramount to realize that you are doing so because of the lucrative odds in flopping a monster (2 pair or a straight) and trapping an unsuspecting opponent who will overplay a single pair.  While this flop in the abstract is in the top 1/3 of possible flops for your hand, strategically it is a bad flop, as lots of hands still beat you, but you are only ahead of a flush draw.  Despite this, I don't like the check.  If you are going to call a bet, you should just bet yourself as that adds fold equity.  If reraised, I'm just folding, but you must charge the flush draw specifically.  I'd probably bet 750 to take it down, but if there is any further action, and I don't improve I will just give up on the hand.  As played, the Ace is a bad card for our hand.  Our opponent is likely to have an Ace as the flop bet was not significant enough to chase out an over.  It is also possible they have Ax and just hit one of their outs.  I can see an opponent making a move like this with a flush draw, representing the Ace.  But if we call we are simply guessing in a bad spot so I just fold.  Keep in mind that even though we lost money in this spot, we lost the minimum, and I believe that is worth it because next time you may just show up with two pair+ and stack your opponent in a similar spot.  It's like fishing.  You put a little worm on a pole and sometimes you just lose the worm and waste your time, but sometimes you do catch the fish.  You're not playing that hand for its 1 pair value, you're playing it because you have lucrative odds to flop a monster, and stack the fish.

Also, does this mean we are calling the SB preflop and leading out with top pair on the flop even though we're only going for two pair or better on the flop?

By that I mean I’m just not going to commit with TP-9K here.  Yet it doesn’t mean that I’m not leading out.  Only my lead out is more of a probe bet than it is a value bet.  If I get reraised, I’m done.  In other words, I call preflop out of the SB, lead out on flop to 750.
