OK, guys, we're playing a 2-60 spread game, which means bets are capped at $60. It's Minnesota where you can bet $500 a hand on blackjack, but these are the rules for poker.
It doesn't really matter though because HU the bets don't escalate quickly enough. Main question is whether I should bother making the 3rd barrel or if it's spew. Comments on other streets welcome.

So...a tilting shortstack straddles for $4 and I make it $12 on the button with JT. The SB, a female asian player who is reasonably sentient but typical live player, calls and everyone else folds.

The flop is AA4 (pot $25)
She checks and I make a bet of $10. She calls.

Turn: 5 (pot $44)
She grabs a medium sized stack of chips as if to say "I am calling" before checking. I decide this is an act, so I bet $30. She thinks for a while and finally calls.

River 3 (pot $104)
Check, hero...?

Umm, u kinna have to dont u?

Well... what r the stacks first of all?

why did you be so little OTF?

she probably was thinking about donking turn, rather than calling. if she did this and then tanked before calling, she probably had a draw OTT. hearts or diamonds are more likely than a SD. the 3 only completes draws that contain a 2 or 67, which is a tiny part of her range.

unless she gets tricky with hollywooding, i barrel river $60.

stacks are near $200. But the $60 bet cap might be more relevant - e.g. to why I might bet small on the flop.

her attempt to grab a chip as if to call is a HUGGGGGE tell. 3 barrel every day
