This has been bugging me since I ever started playing MSS.
I play only against calling stations and I have a hard time putting my last chips in the following scenario. Let's say I'm OOP, I got TPTK or an overpair and the flop includes a flush draw. I bet 2/3 or 3/4 and villain calls. I bet again and villain calls. River complets the flush and I'm first to act...
Normally in BSS this would be another big bet/fold. In SSS we're not playing river. In MSS I'm left with few chips and I'm always commited. I assume it's a bet (allin) and it makes sense since we didn't gave him proper odds to call and on the river he isn't getting back enough money, enough times to cover for the improper odds, right?
However I'm losing a ton of pots this way. Basically 80% of pots that include a flush draw are continued by flush draw chaser. And they're so crazy, will call any bets just to see all cards. For example, yesterday I felt a guy was chasing a flushdraw when I had a set, river brought him the flush (or so I was suspecting) and me a fullhouse and he called a 1.3$ bet into a 0.3$ pot.
Also, what happens when TURN brings a flush card and I'm OOP? Bet turn? What on river? If he made a flush he won't raise it on turn but will probably bet if I just check.
