River is a trivial check behind I think. A couple of hands that are worse probably call a small bet on the river but not enough and you don't want to be cry calling a check raise here. I don't really like the bet on the turn either. One of the benefits of your bet on the flop is that it is likely to help you get a hand with decent showdown value to the river cheaply so I would just take it.
Another point worth bearing in mind is that you should be planning what you are doing on each street in advance so when you make the flop or turn bet you need to be aware that you are putting yourself in a tough spot on the river by inflating the pot. For example if the river is

what do you do when he makes a £25 bet. It is tough to fold getting 6-1 for your money or even when the the

comes what happens if he shoves or bets £50. Again it is a tough decision that wouldn't happen if you checked behind on the turn because the pot would only be £55 so it is much easier to fold only getting 2-1 on a £50ish bet on the river. Hope this make sense but the basic point is to plan your bets around later streets
yeh instinctively i pretty much snapped checked behind the river, but ofc 2nd guessed myself when he showed

and thought i could've got 30-50 worth or value perhaps. But yeh overall i realised that it's still a check now, ty. Good post btw, i see your point about bloating pots and making tough decisons for myself. Althought I think the river decisions you mentioned are actually pretty trivial too. He leads £25 on a

river, Im snap folding. He bets 50 or shoves on the

river, Im also folding.
I think it works the other way round too. Bloating pots like this actually make it possible for me to make my opponents make really tough decisions. E.g. if i'd checked behind the turn, and he snap checks a

river and I realised that he has 9x or 88 or 7x, the pot is only £54 and more difficult to get him off these hands because I've checked the turn. So maybe in a different spot I could "plan for future streets" by barrelling the turn with the intention of making the pot big enough so I can 1.3x pot shove the river for example. Ppl don't mind calling off £20- £40 if they're "probably beat but..." whereas you can apply so much pressure with a £150 river bet. Even if people know you're capable of doing that, they fold on earlier streets because they don't want to face that tough decision with a marginal hand. Fwiw I know most ppl on here are online players and think that live players at these stakes don't fold. But they actually do a lot more than ppl think. Or maybe I'm just awesome. I did a bluff once.
As I'm writing this I don't think it's making much sense actually but I don't know how to phrase it. Do you know what I'm trying to say?
