So if the pot is really big, you go ahead and donate one more bet to it so the passive player who just checked raised you on the river wins a big pot + 1. Interesting.

Since a player is check/calling all the way, he is obviously chasing something, or has something, and the check/raise means he didn't miss (these are passive players, not "tricky" ones).

The check/raise on the river by a passive player means, "I know you have Top Pair, and I have you beat".

I think the number of times that a passive player has checked raised me on the river and didn't have at least TPGK beat would mean the pot would have to have at least $50 in it to be profitable to call in a .5/$1.00 game.

So I think it is safe to say, I am going to fold.
