line checks

Hand 1
Villains running 17/10 taggy hasn't got out of line. My question is, with his stats should we be calling 4 bets with AK? If not what stats does he need to have for us to call a 4 bet. Whats his range? What about if he was running 25/15 or 25/20?
As played line check?

Hand 2

Villain complete unknown just bought in in full this is his 3rd hand at the table.

preflop:
hero has :qc: :qd:
Hero raises to 1 from utg mp calls Villain raises to 3.75, hero calls mp folds

Flop: :jd: :4d: :td:

Villain bets 7 Hero is all in for 34.00, villain calls.

Any suggestions?

Hand 1 is fine, although I think folding pre might be the best play here.
Hand 2 I learn towards a fold. We are losing to every PP 10101+, and we are racing against any AK with a D.

Hand 1 seems fine given how small his 4 bet was, I would usually fold against a 17/10

Hand 2 seems fine to, you're about 50/50 on the flop vs the standard TT+AQo+ 3 betting range & even if you assume he's only calling with a range of overpair, set or AK/AQ with a diamond you still have 33% equity which is fine given the money already in the pot.

I might fold hand 2 pre-flop against a passive pre-flop player. Even the aggro sorts tend not to 3-bet light when TAgg opens from UTG. Post-flop is just gamb00l.
