There was so many ways to play that hand you can't justify just betting higher, especially when there are 4 clubs on the board after the turn card, don't get me wrong amanda11 sounds like he/she played that all wrong especially after he/she knew they only had top pair without the flush.
Should have folded after looking at that, well not true if the opponent bet then you should have cut your losses and got out if they didn't bet then that would be the time to take your advice and hit it with enough to put serious doubt in there mind.
But then again the other player only had the straight which means they missed out on the flush and with 4 clubs down after the turn the opponent themselves sounds more like a wildcard player which you've got to be careful of because sometimes its easier to win against a conservative or tight player then it is to win against someone who goes straight after there luck.
