OK, so I've turned the non-nut straight + a probably worthless top pair on a two-flush board. SB min-bets into me and I've got a player (MP2) to act behind me.
Should I clearly be potting this, only re-evaluating if MP2 calls my raise?
If MP2 calls should I abandon any notions of value betting the river and check-call because of a likely trap?
If MP2 folds and SB calls do you think I can value bet the river if it doesn't pair the board or bring 3 clubs?
If MP2 and SB both call and the river doesn't pair the board or bring clubs should I be more inclined to try a value bet as they might have had draws, or go into check call mode (as if only a better hand would call at these limits, but yeah...)
