Try keeping it one hand to a post. Use the converter but if not a "neater" style would be appreciated e.g.
Hero dealt A [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/diamond.gif[/img] on button
3 folds, Hero raises, SB folds BB calls
Flop x [img]/images/graemlins/spade.gif[/img] [img]/images/graemlins/diamond.gif[/img] z [img]/images/graemlins/heart.gif[/img] (4.5 SB)
BB checks Hero....

Hand 1) I raise here because: I may have the best hand; I want to blow people off of lame J's in case a T hits; I want to blow people off of lame A's also; getting people to fold a lame T also is pretty cool too to partially open up some J outs. Yeah, raise here.
2)I cap pf. limp reraise from the button after 3 limpers in front? This is goofy. This seems very likely dude is screwing around. If this guy is a reasonable thinking player I would suspect him on some kind of broadway suited connector hand such as QJs or JTs etc. AA, KK etc. would have thrown in an intial raise the first time around. Then again, stranger things have happened. This is a tough spot. I would check to begin with and see what happens. Probably just check call because the best case scenario if you c/r is that you leave people with 10.5:1.
3) KJo 3-bets, KTo I fold, A8o I fold, QJo I fold. I would like to know a little more than 24/15, especially how they play postflop. Catch me tomorrow and I may say 3-bet all of these. Regardless no one should say call, it is a must 3-bet or fold
4) It really depends on the types I'm playing against but in the situation that you described I usually just check the turn behind in a multiway pot.
