"One question, do you think to shove with A7s with 12bb is a litttle too early? perhaps still can wait one round or something?"
Nothing wrong with shove if u are at later or mid position. If the table is relative tight, u can bet 2~2.5bb, fold with re-raise. So give u another chance. People re-raise u will also call u 12 bb aii-in. Most time they are better than A7.
