Near the bubble Stars 10+R

[Melchiades]

MP2 had been fairly active, but nothing out of the ordinary. I haven't seen him minraise before now, but this is the first hand at this blindlevel and it might be his standard raise here for all I know. I pushed over the top of him (with AK, but didn't show) 2 hands ago and he folded. I'm 31 out of 42 or something. 27 gets paid. Call, push, fold, stop and go?
