Being check-raised with TPTK, L1 $10+1

[AnyGlen]

After the check raise, I get scared of 99,TT, A10, A9, but can I/should I fold here? In a higher buy-in, I would lay it down, but at the $11s, I think I'm going to see a weaker A here a great deal of the time. Any advice? No relevant reads...

ugh...looks like he got the best of you
i wouldnt be surprised to see foe calling the preflop raise with AT, TT or 99 at this table (or T8, 54, 32)

youre pot committed, you only have 300 chips left
call and start up another game while the cards fall [img]/images/graemlins/smile.gif[/img]
