NL 25 - Top pair, weak kicker. HU. Call on river?

[barthen]

Hi all.
I`ve played poker for a year, going pretty much break even. Now I discovered P2P, and this forum has improved my skills dramaticly.
I`ve changed from FR to 6-MAX, and got more aggressive. Now poker is fun. Thanks a lot to all of you! But there is still a lot to learn. Here is my first post:
