MP3 has only been on the table for a few hands, no read as of yet.

Hero?? <font color="red"> </font>

What was the buyin and any reads on MP1 and MP3?

Your M is over 20, a great place to be at this point in the tournament. I probably fold absent reads.

By the way, I probably fold the first time.

I edited the original post to reflect my reads, thanks for pointing that out. Also, this was a $2500 freeroll, but I wouldn't be sure what to do with this situation coming up in a cash buy-in event either.

I instashove this in a freeroll without thinking twice.

i dont have the time right now to play with pokerstove, but i'm pretty sure i'm pushing the first time around, but if i had just called, then i'm pushing now.

Agreed.

Instapush in a freeroll.

If this happens in a signicant buyin, though, I think I fold this hand the first time around.

I did push, I was just thinking about this situation in a mid cash buy-in even as well, say a 30+3 or 50+5? Does this change my line at all or is it still a push?
