shove - get called by 77 drawing to 2 outs - profit
call/make a smaller raise - get called by A2 drawing to 3 outs - profit a lot less

obv you cant really _shove_ but ~put CO allin

Standard on this flop is propably check/call anything and feel happy about it.
I would consider folding if he bet like 3k but if he shoves or close I snapcall/put the rest in. Anyway in general putting him allin preflop is a lot more profitable because you stack a lot of PPs that way that will find some sort of excuse to fold the flop. Betting the flop with these stacks is horrible, it accomplishes nothing as every worse hand will just fold and any ace will call. But the stacksizes are really hot for villain to think you dont have the ace and will fold your XX when he has 77.
