You need to make a bigger raise on the turn, flop play is good, but on turn you need a bigger bet, maybe 30-40 more at least. On the river I'd push over his minraise, yes sometimes he has a flush but I think you'll find KQ, KT, KJ, K9 and so on more often.

yeah man learn fundamentals right now, its great that ur learning, i went through wat u are doing not that long ago

flop is fine, u are getting a very cheap price to see turn so thats ok.

turn: u hit the absolute nuts. often when u are beginning ur heartbeat goes crazy when u get nuts (at least mine did) and i get really excited and i keep thinking "what can i do so that they dont fold" and think that i should minraise and stuff, which is what you did heheh.

dont ever minraise alright. i used to think it was good but its just not so NEVER minraise EVER ok :D

you need to raise a lot more on the turn, raise it to at LEAST 30, and preferably 40 c

if he doesnt call, so be it, but u want to make the maximum from the hand and min raising him 14c isnt going to do that.

by betting 40 c u are making the pot increase by at least 80c, allowing you to make a large legitimate bet on the river which he'll hopefully call since it will be getting him supposedly good pot odds.

so raise like 40c on turn. if he calls, pot would be $1.20 i think, so bet around $1 on river.

The diamond flush completing kinda sucks but since its a "backdoor" flush and not one that had 2 suited cards on flop, dont give him any credit for it, as its rare that someone will randomly turn up with a backdoor flush here. whereas if the flop had 2 diamonds in it and the river diamond'ed up then u should be scared and consider folding if he bets pretty big.
