Thank you all for your replies. I was thinking that a shove preflop would have been the best play.
Heres what happened: (disclaimer: i played this hand effing horribly so please go easy on me)
I reraised to 13k trying to send a message that big stack should gtf out. He called my raise. Flop comes Tc Td 6c. At this point I'm concerned hes got a monster (AA, KK) as he flatted the allin, and then called my 3bet. As i said I'm on the bubble and this guy can send me packing right now. I really just wanted him to fold preflop.
I checked the flop, and villain bets 8k (about 1/4 the pot). at this point it just feels like hes trying to suck me in and I'm more and more fearing AA or KK. I should have taken all the time i needed to go through his range. 88+, >JT
I'm really only a dog to a small percentage of his hands (AA, KK) im only 36% to win, TT im dead, and Any T im 25% Anything else (JJ,QQ >JQ) im a favorite at 60% or more.
I succumb to my fears of being bubble boy and fold. I realize I should have Shoved on him here and that a preflop shove would have been even better. The other thing i could have done is just called and seen a flop.
In the end, villain turns up j6o and the 4c comes on the turn giving the original allin 2 pair and triples up.
I was not happy. I did manage to cash 7th (the same big stack raised 4.5 bb and I shoved on him with jacks for about 5bb, he had AQ and spiked a Q on the flop )
I'm mad at myself for being scared to miss the money but it is not a failure as I learned a valuable lesson with this hand.
