2/4 B&M - Bet or checkraise monster flop that I capped preflop?

[gobbledygeek]

(originally posted in BBV but a poster questioned my play so...)

2/4 B&M, 10 handed, loose & passive table

PreFlop: Hero is MP1 with J [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/diamond.gif[/img]
UTG calls, UTG+1 calls, UTG+2 calls, Hero raises, MP2 calls, MP3 folds, CO folds, Button 3bets, SB calls, BB folds, UTG calls, UTG+1 folds, UTG+2 folds, Hero 4bets, MP2 calls, Button calls, SB calls, UTG calls

Flop (5 players, 23 SB): J [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] 2 [img]/images/graemlins/diamond.gif[/img]
SB checks, UTG checks, Hero...

My plan was to checkraise and then keep raising till the cows came home, my thinking being that if I bet then button could raise and then I might not trap SB and BB for 2 bets. But now I'm thinking that letting this check thru would be horrible, that and I could also get a 3bet in if button does raise plus SB and UTG might come along for the ride regardless.

So, is it retarded to cap preflop and then not lead out on the flop? Or is a checkraise ok here?
