Was This Just Too Weak??

[irish79]

1/2 No Limit Cash Game. Live game setting in a BM Casino. Min$100 buy-in Max.$300

Hero just sat down at table with max buy-in of $300 which is roughly 15% of live cash game bankroll. ($2000)

Very 1st hand Hero gets JJ in MP.
UTG + 1 who has Hero covered (roughly $700 in chips) moves all-in preflop.
No reads, never played with this guy before, and it is the very 1st hand
My first thought was 66-TT's or AK, then thoughts of QQ or KK crept in.
I seriously had no reads on this guy other then the fact that he had doubled his chip stack in his time at the table.

I had not put any money in the pot and Hero figured it was not the best time to tangle with a guy who could bust me. I had suffered 2 previous losing sessions prior and I was just not looking to start in a -$300 dollars right of the bat.

Was this play excessively weak? Should have I taken a chance to double trough on my very 1st hand?
