(55 speed)- wtf does this line mean?

[RubbishCards]

Don't have the HH so I'm doing this from memory.

Early in level 1, i.e. 20-40 blinds, no reads, neither of us has played a hand. I'll leave my cards out of it for now, I'm just interested in what the other guy was doing.

Villain opens to 100 from EP, I'm next to act and I make it 180. Folds back around to villain who calls.

Flop JJx, two diamonds. Villain checks, I check behind.
Turn blank. Check,check.
River Ad, for a final board of AJJxx with 3 diamonds. Villain checks, I bet 200, villain raises to 650, I fold.

The river CR is really bugging me, and I'm trying to figure out how it can be anything other than a bluff. If you're villain and you have a strong hand (say, trips or better) would you really have the stones to check to me on the river (with the intention of raising) after I checked behind the flop and turn, and if so can you explain why?

2 possibilities i can think of
1. he just KNOWS you are bluffing, but isnt convinced he can beat your bluff
2. He has quad jacks, and read somewhere you should slowplay quads - and is hopeing you finally get some balls and bet on the river.

Either way, its pretty silly.

The first option isn't that silly.

He may have flopped a jack, and put u on ace high after u check flop. He knows youre probably not calling turn so he checks, then he thinks u hit ace on river so he checks expecting you to bet your pair of aces. Of course, bluffing is always a possiblity (Harrington says at least 10% for any player). But I do agree with you, that people very rarely check a strong hand on the river if it looks like it will get checked behind, so betting the river is not bad against this line (of course I don't know what you had)

This is my best guess, as well.

What sort of hand do you reraise to t180 with here, BTW?

IMO, your line right up to the river fold screams AK/AQ. If I was the villain and I was going to bluff at this board, I would be leading the river because I don't see you checking AA/KK on the flop and the turn. In other words, because I don't see this as a spot for the villain to bluff, I think your villain has a J or a strong A.

As for your line, to quote the subject "wtf"? What are you re-raising from EP that you check twice, and fold to that re-raise? TT? Also, his raises is 60 so you bump it another 80? I guess you are just trying to isolate while giving him great odds to call? Does this mean KK? I'm really confused.

In summary, your preflop action says AA/KK to me. Your line until the river says, AK/AQ and your fold on the river makes me think 99/TT. I'm confused!

I had AK. I didn't mean to make a big mystery out of it, I just didn't want the discussion to get bogged down with how I should raise more PF and c-bet the flop etc. I want to establish whether a good player could conceivably checkraise the river in that spot with any hand that beats me.

After the river checkraise I basically decided that he's either a good player bluffing or a bad player trapping. I used my 5 microsecond timebank to decide that someone who raises PF to 2.5BB at level 1 is less likely to be a strong player and so I went with "bad player trapping" and dumped it.

Regarding PF: I didn't like his 2.5BB raise, so I bumped it up a bit to stop the rest of the table joining the party. I would have flat called a slightly bigger raise, and I wasn't trying to make him fold.
