I don't really like the call. First off, i would be very hesitant about flat calling the $2 on the flop after a bet and a raise. Also, you will probably have to call more bets on the turn and river. So right from the start you are commiting too much money with a very marginal hand that could easily be beat. Same with the turn. Building big pots with tpmk is not usually a good idea.

The river, well i guess you had a read, but i would still advise against this call. His betting pattern shows some strength, i don't know what i would do on the river but i defintily think in the long run it is a good idea to get rid of this hand earlier. This is online poker, your not familiar with your oponents. The next two times this happens you could easily be beat and lose a huge pot with a mediocre hand.

Don't want to be an ass, but this kind of looks like a random call that got lucky. What's your "read" again?
