set vs fish on 4 to a straight nl200

You posted the wrong hand here.

This hand is mainly about whether he has worse AX and twopairs vs straights and flushes.

So our options are between block betting and check/folding. I don't think his range is overly wide here despite him being loose. Most of his calling is done from the blinds.

This seems really close, depending on our assumptions about number of flushes he has in his range and also how often he calls AX on the River. Having the WTSD may help.

1) All Suited Aces, Some off suit Aces, All twopairs and flushes and straights

If he has lower WTSD I will check/fold. If he has super high WTSD like 40% and he is really passive then I prefer your line. As you can see from the equities for the optimistic and conservative estimates, it is a close decision.

Thanks.

His wtsd is 18% in 140 hands so i guess a check/fold is better . I thought it's a clear block bet here ,didn't really thought about check/folding.

Thx
