Pre-flop and Flop I think is OK.
2 flush draws are possible, so I defend my hand (And here I bet really big, kinda make myself pot committed). My intentions on the T are to b/f. Should I play T - way ahead/way behind?
What to do on the River? I have problems to fold my hand to possible backdoor flushes a lot ...
