The fact that I'm posting this at 6pm suggests this didn't go well but I'm sure we can look past the results oriented part of this

DTD £100 f/o. 10k chips, 30 min clockl.
level 5 - 100/200-25
Villain (young aggro player, playing 15-20k) raises to 550.
Hero (playing 12k) calls on button with

Both blinds (passive) call
Flop:

Checks to hero who bets 1350
SB raises to 4000 (playing about 20k )
BB ships it in for about 12k
Hero.... argh?
I was all ready to ship it in against the SB but should the BBs involvement make me a bit more wary here?
