General KK on A high flop question.

[wrschultz]

One situation I'm always unsure of is when I put in a re-raise in position preflop with a big pair and get called by the initial raiser and the flop comes A high.

Using a Pokerstars example, in a $20 MTT where the effective stacks are 1500 at 25/50 and I re-raised to 500 preflop. I now have a pot sized bet behind, and when I'm checked to, I usually just bet about 600 with the intention of calling a push. I know this is bad, but I really don't know what else to do.

My reasoning is usually, that I should make this bet because it looks stronger than a push, and because sometimes weak aces will fold. I always fear checking behind, because I think it just encourages villain to take a shot at me with any two, and I'm folding the best hand a lot of the time.

I know that my goal here should be to keep the pot tiny, but I just don't ever know what line to take to make that happen.

Thanks.
