The flop check/3-bet is very intimidating in my opinion. It's likely SB has a very big made hand or a very strong draw (either a flush draw or OESD, or possibly a combination of both). For this reason, I like raising the turn and taking a free showdown, should the opportunity arise. This way we can charge draws, fold out any overs MP3 may be holding, and fold too any further aggression. It's likely we have less than 2 outs when behind, and thus folding is relatively safe.

The problem with this, though, is MP3 is behind us, and this will likely foil our free showdown play. Though, given the hand range I still like raising the turn.
