If you have 910s in a cash game and you dont call a bet to just double the big blind then you are playing in a game that you shouldnt be.
Suited connectors like this are the sort of hands that you should be playing in any cash game, regardless of your position and the other players at the table.
For just 2x the big blind is about the cheapest you can see a flop for online and suited connectors are the best drawing hand out there. It is a certain call in any situation as i said before.
Im not going to get into all the pot odds and implied odds as it will take too long but if you think that 2x the big blind is too expensive to see a flop for then move down to a level that isnt too expensive, start playing these sorts of hands, and start to see an improvement in your winnings.
