Nice to see you back, Bill. Lookin forward to some more insightful posts
If we're following gap theory here (which applies perfectly to TAG players), then we can only call with a hand stronger than what the raiser would raise with from that position. So we would need a pretty strong hand here to call, but since we're so deepstacked, we have huge implied odds
if we hit with a lesser hands.
So I personally will call this only with AKs, big pairs JJ+, but will also toss in suited connectors in case we can stack him postflop.
