With the caveat that I'm not an especially good player, and haven't crunched any numbers, I'll give a thought.

Personally I would say yes it probably is a bad move, albeit an understandable one. You only lose to three combinations of diamond hands: QJ, J7 and 76 and I can coem up with more hands that I think would consider playing aggressively that don't beat you.

Any queen high flush may well go with it, as it makes it very hard for you to have nutted diamonds (9/13 diamonds would be in play between the two of you and the board). Likewise a few smaller diamond hands may well go with it as well.

If the villain has a diamond in their hand then certainly at lower stakes there is a decent chance they just don't think you have a flush and are treating a nut straight as the stone nuts. A hand like AQJT with a diamond may feel it can push you off a hand containing small diamonds as well, because it would be more unlikely that you have a nutted flush..

There's also a small chance it's a stone bluff.

From that I think it is a call, particularly as the first time you get genuinely aggressive is the river raise. I think it sucks, but is one that should be made. Although I'll happily bow to players with better knowledge of the game than I.

Thanks very much for this. Brings up some things I'd not really considered much, and definitely not at the time. In particular the 100% checking range stuff. I know at the time I definitely didn't think about the fact that my bet would normally only be folding out hands I beat, whilst the majority of calls are hands that have me in trouble.

Thanks again for taking the time to go through this. I'm generally happy to risk exposing myself as an idiot player on the hope that it improves me.
