Top pair in the blinds?

[Taraz]

How did I play this? Good? Bad? I seem to get into trouble when I flop top pair with a bad kicker in the blinds in level 4 and above.

TPNK is huge trouble in the middle stages. I will generally treat it like 2nd pair and check it. If the only better is a weak bet on the end, I'll sometimes go for a strong check-raise and try and take it down there. If not, that'll be the last money I put in.

Since you bet out, the smooth call on the nearly drawless board could be another J or total garbage (this is the 10s, right)? The turn could complete a wacky draw, but I think it's more likely it didn't. In any case, you probably have a 50-50 chance at best of pushing MP1 out here and you have hardly any showdown equity (you effectively have 2nd pair TK).

I think the bigger question is: Do you really want to risk the tournament on this hand? If you fold, you still have plenty of chips. If you win, you're a larger stack, but not massive. If you lose, you're out.
