I can make it bigger, yep, but he never folds FD on the flop anyway. If I check I can not ch/c, there is just no way to play profitable after ch/c...
What do I achieve with big turn bet? He is maybe folding his FD and that is it. Maybe - because his FD mostly is with overcards and he will continue. If I bet big he will most likely fold his weak pairs 44-55 77. I don't see him folding TP to the big bet here.
What do I achieve if I bet small? He should raise his strong hands. He will raise his set on the flop most of the time, if he has not, he will do that on the turn to build up the pot. He will raise also trips. When calling such a small bet his range is almost always very weak. My hand is not so strong that I need to defend it much, I might be also behind already e.g. TT
There is no straight dro as I have 88, only 2 combinations of 78 are possible 78 spades will raise either flop either turn good amount of time. and it is very unlikely he has straight flush on the river
On the river I doubt that kind of player will valuebet 9x. A9 will be happy to get to SD, 98 is unlikely. And if betting such a big bet - what hands will call that? 77/88? I believe he would bet smaller. He also check behind his 77 or smaller pairs.
I think he can only bet w Tx on the river.
