Party 40K: Monster in BB - Chip extraction

[illegit]

MP1 is loose and a bit of a donk. SB seems pretty straightforward and hasn't got too far out of line yet. His re-raise was a shocker though. If I re-raise here I'm pretty sure MP1's stack is going in and going in with not much of a chance. I want SB's stack in too though
