Results follow:

hi all,
that Mp2 looks very weak to me hi raise and call to that minraise - so our hand is great against his range
BU - no comment
BB - he reraise 300 to 375 (raiser and 2 cold call)

so what is the best line here - fold is not a option
if we push - we face coinflip with lots of dead money
if we call - we can see cheap flop and get some more value when hit

thx
