So I was holding AA in SB, UTG+1 opens with minraise and everyone folds to me. I have only 11BB and my goal ofc is to get allin here preflop. I just didn't know which is the best play shove or 3bet small. I was new to table and didn't have any info about opponent. In my opinion if he opens from UTG+1 he is probably holding at least something good, so giving a rope and just small 3-bet could be a good idea. Also there is I guess 0% chance that he could just call even if he had some AJs type hands just because of effective stack and even if he is fish and don't think about effective stacks he is also himself too short to do that. And if he has nothing big then I guess he would fold in both my plays. So would like to hear other opinions.
