glglgl m8, seem to be on a heater of your life atm
just watched some hands, in that J7hh hand turn check seems pretty bad in a vacuum readless (coz obv i'm readless but you're not). i'd also give consideration to raising flop, but only if you're happy stacking there. you've got 43.6% vs. JJ+/AKhh/AQhh and prob enough fold equity that he doesn't need to fold very often for it to be a +++EV line. but i guess with the whole MTT thing of stack preservation if you have a big edge over the field is something that you obv take into consideration, coz you were still ~50bb deep iirc.
/end strat (and prob don't listen to me coz i play mtt's once in every blue moon)
