JTs in BB - not my normal play

[rkaufman]

Typical Party 2/4 (but slightly more loose and passive than usual). I probably had reads on some players, but I don't remember them. :-)

5 limpers, SB completes, and I raise JT spades in the BB. All call except SB.

Flop (13 sb): Ac 4c Qd and is checked around

Turn (6.5 bb): Ks I bet and get one caller in MP

River (8.5 bb): 2h bet/call

MP shows A6o and obviously MHIG.

I was up $130 at this point and feeling sassy, hence the strange play. My thinking was that if I made a straight, I would get paid off big by players with big pairs.

I checked the flop intending to call one bet or fold to two. I was pretty surprised when it got checked around.

And of course the rest of the hand played itself.

Am I totally out of line raising JTs in this situation as a rare alternate play? All comments appreciated.
