4th is a clear fold. You said something about implied odds, but if you make a flush before the river you’ll have a four-flush on board – so it’s actually a case of reverse implied odds, since you don’t make money if you hit (at least if your opponents are sane). If you had two spades in the hole it would be a little better (but still not good enough to call). Besides, spades aren’t exactly live. Needless to say, your straight possibilities are very, uhm, vague.

5th is a fold too – spades are looking deader, so all you really have is a gutshot with no over cards (they wouldn’t help anyway, since you’re probably up against two pairs already).

The river check is truly horrible. Bet your damn hand already. If you were in there with queens up – would you fold? In a 11 bb pot? No way.
Value betting on the river is extremely important in stud. It also a lot of fun – first they make you pay to suck out, then you make them pay to see. I love it [img]/images/graemlins/grin.gif[/img]
