Is this pretty standard? I don't like chucking in 20% of my stack to fold to a rr, but since I'm probably in great shape against either cold-caller I thought it might be worth it.

I'm assuming UTG+1 range is almost excusively AA/KK at this point, so I can't call or shove. Do you like "squeeze" raising this PF, or rather calling and playing a smaller pot in position w/ AKs? Maybe raise more(?) or less?
