Hi all, 

I noted few question during latest session, would be nice to hear your opinions on following spots:

a) utg 70\25 (lets say 50hands data or so) open for 3bb, action folded to hero on the CO w\ AkJ6(one suit to Ace). BU tag, blinds 40\20 kind of guy and reg.

is flat default here? would you ever 3bet, fold?

b) CO 50\35, open for pot size, hero BU w\ JT92ds.

is it much merit for 3b? I'm kind of on a tag side and 3b around 8-9% otb., trying to find more spots for good 3bets - could it be one of them? 

I know it depends much on post flop abilities and game style.. but what hands (if any) could we 3b from speculative ones?

should we consider calling in spot B?

thankful for any piece of advice

Andrew
