Heads up late in home game. Easy call? Easy fold? Neither?

[slogger]

Heads up at the final table of a $50 buy-in home tournament. First pays $385. 2nd pays $255.

There are a total of 85,000 chips on the table.

You get heads up with a solid, not overly tricky opponent (familiar with 2+2). You have about 63k and he has 22k. From the get go, you're chipping away with raises from the SB (and typically showing him pretty good hands when he folds). He's also folding a fair number of rag hands in the SB, so things are looking very good for you.

Blinds are now 1k/2k. You have grinded him down to about 9k, and he has to post 1k of that in the SB.

He pushes his other 8k in. It's 7k more to you. You look down at K6o.

What's the play and more importantly, what are the 3 most important considerations in this decision?
