depending on stack size. if he does this with >15bb left, then he is a donk. it is too easy to wait for a good hand and clear him out even though half of the time they suck out on my AA KK and AK on ftp. Q 10 is definitely not a good call if you have > 15bb or even with 10bb. Why choose to coin flip with them when you can put all your chips in with a much better hand. fold and wait for a better spot. Even KQ is a fold if your stack is deep , so is AK facing reraise all in at early stage. Don't coin flip with donks when the stack is deep at early stage of STTs.
