The only reason I didn't c-bet this flop is because I've been doing it fairly often and I was just mixing up my play. Especially in case a diamond fell on a later street giving both of us a flush. When he checked behind I thought I could take it down when no diamond fell (thought that's what the call on the turn was). But the re-raise on 5th street makes me think he's holding that K after all.

im thinking your beat because a.) this is NL5. no villain is thinking. this is a value reraise. b.) we have no clue what he's holding, and c.) is $1.10 worth an extra $2.65?

i would prefer if you did cbet this flop. its HU. it may be all diamonds, but it looks good otherwise. and most importantly, its HU. dont worry about varying your play at NL5. who do you think will notice?

****...good point lol. Thanks.
