Being a limped pot the ranges of villains become very wide, because no one took the initiative to filter the speculative hands that could continue at the price of 1bb.
On the flop you are betting your hand a little face up. Presumably a major AX would have tried to collect more money preflop. So now your value range is oriented towards the weaker Axs that here are semi nuts on this board.
You probably wanted to prevent someone from improving their flush draw. But when you bet very big size on the flop, you are isolating yourself with exactly those hands that V called speculatively preflop and now on the turn they are flushes formed like: JTdd, QKdd and A7dd.
From this point of view, all the information we have about the SB could be very helpful.
As played we could fold to his turn raise. But if planning to call on turn, we should still keep fold equity for an overbet, as the open dynamics of this table tell us that a limper could have some random combinations that possibly beat us.
