Im new here but would really apreciate some help from some experienced tournament players. Late in tournie with 1400 people, $20 buy on on party. I am moved to a new table with 15k in chips and average with bb o 2k. Averages stack is 22k or so and there are 50 people left. An unkown pushes all in from small blind against me and i have A/10s in big blind. I felt like he had weak hand and was trying to pick up the blinds. Is it correct to call here or should i just wait for a better spot? Thnks for the input
