Arkady says: If villain bets out of position on river, villain has a hand 99% of the time.

Arkady also says: This bet is even more threatening than a river raise, due to the inherent tricky nature of the game.

Followup: It is hard to gauge the strength of the hand, but it is generally futile to call this bet w/A high and dangerous to raise. A stark difference from the out of position turn bet a bet I raise frequently.

Comments: This happens much less frequently in 5/10, but interestingly enough is actually a more straight forward and basic approach to poker. It is almost ABC in a sense, because they fear the check through so often. I notice such behavior from some of the old fogeys playing in the casinos, whose passive river bet generally spells disaster for holding as strong as TP/TK.

So, while I have stopped calling this w/A high there are certain oppoents vs. whom folding weaker holdings like middle pair or TP/no kicker might be fruitful. They are slowly, but surely sucking out 1 bb out of you everytime they pull this off.

For anyone interested I can pull up quite a few hands that illustrate this very point.
