Normally I don't bet this large but the table was loose.

I think there is no room to communicate that I have an overpair instead of cont betting so if I continue it will be for my entire stack - agree?

He could have trips or better or AT, JJ, QQ, TT or maybe a draw but I wasn't thinking draw.

Does the fact that this was a check-raise indicate he's not on JJ or QQ or maybe even AT(tho I think AT is more likely to cr than JJ or QQ for reasons I can't explain).

Most importantly, is this a pretty easy/auto-fold?

I always make notes on people who lose their stack w an overpair: I'd hate to make notes on myself.

thanks a lot
