(Stars 27 Turbo) JJ facing two all ins preflop

[Melchiades]

MP is a complete maniac. Has probably been all in preflop 10-15 times already from the blinds was 15/30. He has been up and down from 1000 to 4000 to 800 to 4000 again already. Never sees a flop, no limping just pushing. Has played the whole SnG like the blinds were 200/400 already. You get the picture. SB has seemed solid, and is obviously aware that MP's range is huge here.
