Event #12 $1500 6max - It just got cold in here...

[SossMan]

End of the first level of the $1500 6max WSOP event.

My table is pretty weak, but I've been playing a little snug myself. Haven't really shown any out of line plays. I've opened my fair share, but nothing super crazy considering it's shorthanded.
I called a shortstack's utg AI w/ TT and lost to K2.
Next hand I call his AI w/ AQ and lose to TT.
I build it back up to around 3600 when this hand happens.

Blinds 25-50
Only other good player at the table who busted a lady, then got bad beated in another big pot, has 3400. I have 3600.

I open from CO w/ T7ss to 175
Good player in BB calls

Pot (375)
Flop is Td 7d 6s
He checks
I bet 300.
He checkraises me to 1k straight.

Decision point #1. I'm kinda lost here with the stacks.

Let's say I called.
He bets 1k more on the offsuit 4 turn.

I'm still lost.
