when two plays are so close, if I make a mistake, I know it won't cost me very much, then fine
Build small cost plays into the repertoire which provide built in cover - best examples EV Max strike points think I18
8v6 at tc1 - just hit - they’re way too many 8v6 hands less than tc1 not worth the double and using risk averse greatly reduce the number of hands that could expose you plus any number of I18 plays - oh…wait…not exceeding 18 I18 plays.

An ES10 game 14v10 where TC 0 surrender is basic - just hit with 1 unit and surrender any multi unit bets

etc. etc. etc.
