well.. considering that u already put so much money in the pot it's super tough to lay that one down.. Especially when u actually got what u were drawing all this time..
I have the same problem :)

But I would've think for quite a while before calling if tight player check reraised me so quickly.
I mean timing is one of the most essential things in poker - especially online poker.
Also to slow play 2 pair on flop - thats just gambling :P

it paid off though.. bus as Sklansky loves to note - on the long run those people loose money. Always.
