Default ($320) 10 BB stack, SB Completes, Check or Raise Marginal Hand?

UTG and button are solid regulars. MP is loose-passive. SB appears average-ish -- 22/12/1.5 after around 70 hands. Hero has a TAG image. Leading up to this hand, there has been no blind-on-blind play.

I would say the above situation is a fairly common one in mid-blind play, and there are several questions you should ask yourself before deciding whether to push or just take the free flop.

1. How well does your hand play post-flop? Since you have position, if you have a hand that plays well post-flop, you should often just check and take a free flop with position and your hypothesized decent hand (e.g., 8 9s, T Jo). In this case, your weak king-high, while a fine hand against the random distribution, does not play well post-flop. So this factor argues for pushing pre-flop.

2. Is your opponent likely to be trapping? If he is a good player and either of you have 10 BB or less, then you should strongly consider the possibility that Villain wants your action. Also, if you have already pushed on the same player earlier, and he smooth-completes again, be weary. In this case, neither factor applies, so again this argues for an immediate push.

3. What is your risk/reward ratio? Here Hero is risking 1800 chips to win 400, giving him between 1:4 and 1:5 on his steal investment. When coming over top of a normal steal raise, you would usually want better. But there is substantial fold equity here, and so this factor is roughly neutral.

4. [Less Important] Do I need/want to gamble now? Answers here are No and No. With a stack of 9 or so BB after the blinds pass, Hero does not need to force a move. Furthermore, there are likely to be many excellent stealing opportunities with a solid regular one to Hero's left. So this factor argues against the push.

Since I place lower weight on Question #4, and all the other factors are positive or neutral, Hero should indeed push here.

Incidentally, while software cannot account for all these factors, let's see if using some reasonable assumptions an ICM-based program agrees. For non open-pushing situations, I prefer SNG Wizard. Here I assigned Villain a 40% complete range and 8% re-call range, and Wizard's output was a .42% equity edge for Hero to shove.

Always nice when software agrees with one's reasoning process [img]/images/graemlins/smile.gif[/img]
