Check turn in 1, 2 just seems quite a strange line to take

H1 You could make an exploitable fold if his stats are going to converge to these values. His sizing is quite big and AJo plays quite poorly against a 3bet, would rather flat JTs instead. As played on the turn I don't know if that is a value bet or a bluff. Did you bet just because it is top pair or....? If you're going to bet, use a smaller sizing to actually make it possible to get called by worse.

H2 Don't 3bet preflop

1 - Check Turn. Why should we bet here? Not for value; TPGK is not good enough vs. an opponent that showed aggression on A-hi. Not as a bluff; V will fold as good as nothing. The turn card isn't dangerous for anyone.
We have decent SDV and so we should check. Check-call the river on safe boards and decent sizing.

2 - Flat PF. Again; why should we 3-bet here? Not for value; ATo is not very good vs. V's continuing range. Not as a bluff; ATo is not bad enough vs. V's opening range.
ATo is in a decent shape vs. V's wide opening range from CO and thus should be a call, although I like to fold here. We're ooP and ATo is really the bottom of what we should call.

Flop - Waaaay to big; it's a bone-dry board so 50% should be enough.

Turn - Giving up is the best play here.

I don't understand the point in the thread, you want help with 10nl sharks right?

But you post one hand with no back up information regarding it expecting us to respond with an answer based on one hand with no information? just ABC steam roll through him and play your prem spots. call it variance if his ahead and donks something.

Try giving us information on the shark, how he plays, how he floats, what he does in x-spot given x-scenario and what you put him on.

Not just a hand from your HUD. maybe he is a complete fish disguised as a reg? and why in the hell are you 3 betting to 10% of your starting stack with AT against a "shark"

Give this a little time to sink in, OP.

H1. Bet bigger pre. More like 7BB. Fold to three bet. As played Raise flop, check turn.
H2. Flat pre. Check fold flop
