I am new to cash and having a hard time making the adjustment from MTT's. Trying to perfect my short stack game, typically buying in for $100 at 1/2 but am losing fairly consistently at -20% ROI after about 20 BI.
One issue I need advice on is pot-committedness in cash. I know it is not the same as in MTT's, but without a better understanding of how this concept translates to cash, I find I often commit chips and then end up folding, which is killing my ROI.
Take the following hand as an example:
Played at the table for about half an hour at this point, haven't played one hand. Get AJo in MP, raise to table standard of $10, everyone folds except SB, who calls. I have $90 left, villain has about $600 and is a 60-ish man who might be aggressive but not much of a read at this point.
Villain checks dark, flop: Ks8s2h, I bet $15 into $22 pot, villain calls. This is just a cbet by me, I do not have a spade.
Turn: Js
Villain bets $20 into $52 pot. I think and end up calling, not putting him on the K and wanting to evaluate on the river if he has the flush.
River: 9c
Villain looks at my stack, which is about $50-55 and puts out a $50 bet. I don't know what to do, as I know he can bluff this much with his stack in order to take down a $95 pot, I also know he can have a flush, a K, or QT. What should I do and is there a better line?
